The scope moves to the object and begins tracking it. i use a skywatcher 200p reflector on an eq5 mount and a 90 long exposure webcam and have had good pictures of various dso,s and planets.all at a cost of less than 700, Dont take my word for it cos I am new to this and not yet got my Dob!! A scope which is good for the former isn't good for the latter. Moreover, stars hitting below 14.5 magnitudes are super visible with the 8 inches. The most important factor, in this case, is the place. Under good weather conditions, you can also notice the flare stars in the Wolf system. The ISO 3200 value has ended up being a great balance of high sensitivity and low noise for my short exposures. This is not a common way of imaging, but I've found that it can indeed be done. Fairly bulky and heavy. Here we focus on becoming a knowledge hub for astronomy and astrophotography enthusiasts. It's not easy, but it works. You currently have javascript disabled. Together with the Sky Commander, they make up what's called a Digital Setting Circles system (DSC). Description Introducing the new members of iOptron strain wave gear mount family - AZ/EQ dual mount HAE43 and HAE43EC! And, a 6-inch aperture in a Dobsonian means you should get useful views of the moon and planets. Moreover, you can see the Triangulum Galaxy (M33), Leo I, and NGC 6822 are some of the clusters with this 8-inch telescope. This mirror is just slightly smaller in diameter than the tube of the telescope itself. Locate faint, deep-sky objects in seconds and see them in more detail . One of them sits right on the center of the altitude bearing and the other sits right on the center of the azimuth bearing. Read our online reviews of Dobsonian telescopes Also, much more of Jupiters cloud belts become visible. Objective Lens: Achromatic, crown-flint two-ply glass, hard-coated Aperture: 60mm Focal Length: 910mm Focal Ratio: f/15.2. But with very faint deep sky objects, it's not so easy. Have some fun, etc. As for astro imaging of planets/moon , you can only really work with a webcam (SPC880NC etc) and using Sharpcap is best, you will record what you see by recording to video and then putting the video through Registax (etc), this will break the video down into individual frames that you can then work with. Is astrophotography possible with a dobsonian telescope? Top of the list for deep sky imaging is a beefy equatorial mount. The Z10 Dobsonian comes with everything you need to get started in the rewarding hobby of astronomy including a 2" 32mm eyepiece, a 1.25" 9mm eyepiece, a 2" focuser with 1.25" adapter, a 8x50 right angle finderscope, a 1.25" Moon filter, a collimator cap, a built-in cooling fan, and more. But, it provides the additional possibility of imaging, if you have a reasonable visual setup. The details of the Moon will be clear as daylight. After the camera is inserted in the focuser though, you can no longer see the object to do this. Free Standard Shipping. The vast majority of astrophotographers out there use German Equatorial Mounts (GEMs) to accomplish this, which are designed to track the motion of the Earth very precisely. But what do I mean by "good data?". Astrozap Dust Cover for 16" Newtonian, Dobsonian and RC Telescopes Flexible dust cover for telescope tubes from 400 mm to 450 mm diameter. If you know you want tracking then you're not giving away a whole lot by going with the 8". Many of these long exposure photos are then stacked on top of each other (to increase the signal to noise ratio) and processed with photo editing software to produce the final image. For example, I might tell it to take 200 photos, each 10 seconds long, with 4 seconds between each photo. As has been said astrophotography is not visual observing. At this point, I can no longer see through the scope to see if an object is centered or not. However, if you want to view the clusters in great detail, then 12 inches is going to be better. Imaging with the Astro-Tech 66mm Refractor - Review, http://stargazerslounge.com/groups/video-astronomy.html. Orion SkyQuest XT6 Classic Dobsonian Teles. Patented, award-winning StarSense sky recognition technology uses your smartphone to analyze star patterns overhead and calculate the telescope's position in real-time. Table of Contents Drift Method Step 1: Setting Up Your Telescope Step 2: Adjusting Finderscope Step 3: Start Recording Step 4: Joining Videos Driven Method Equatorial Approach Method It has to do with the parabolic, concave shape of the primary mirror itself. You can see the objects within our solar system pretty easily. If the goto happens to miss slightly, though, I can use the remote pad to slowly move the scope around manually until I find the target object in the eyepiece. If you are lucky, you can see many faint comets and asteroids. A scope which is good for the former isn't good for the latter. The answer is yes. Coupled with (say) an 8-10" Dobsonian, you can display 16th magnitude stars on a screen in REAL time. With payment plan. You can definitely see more than planets with this. I did happen to randomly catch an ISS transit of the moon one time with my phone on my 10 dob about mid 2020. Note that even with tracking it'll be hard to take great astro-photos with a Dob. This insures that the two mirrors are property lined up with each other and the scope gathers the maximum amount of light it can. The cell evenly supports the back and bottom edge of the mirror to prevent stressing the glass, which can affect the images the scope produces. I select it in the Sky Commander unit and press "goto" on the remote pad. Nobody is trying to put off budding photographers. Here is a better version of the 6 inch Dobsonian. Now I can finally swing the scope over to the object that I intend to image. It's an 80mm short tube refractor that mounts to the mirror box using a 2"x 2" piece of oak. The primary mirror is concave and sits at the bottom end of the telescope, closest to the ground. It consists of a small device that sits in the camera's hot shoe and a remote control that communicates with it. This system uses two points in the sky to create a virtual map of hundreds of different objects, which are stored in the computer. An intervalometer is another very useful piece of gear for DSLR astrophotography with a Dobsonian. I manually push the scope over to Polaris and center it. On my F7 with the SPC880 it takes approx 12sec. This large 10-inch Dobsonian has a higher price and is better suited to more advanced users. This is one of my favorite nebula so I was excited to finally see it. Because this telescope has higher magnification, it can capture sharp planetary images. There are mainly 3 methods to do astrophotography using a Dobsonian telescope: Drift method, Driven method, and equatorial approach method. My first attempt at imaging the horsehead nebula! The light then continues down the tube, hitting the primary mirror at the bottom of the tube. When it comes to using a telescope, we like to see 3 things. Exposures of several minutes require that the telescope stay perfectly centered on the target object the entire time. Macavity is right that video is a real possibility with a tracking Dob, so you could certainly start with that. If you've gathered lots of good data, then the image processing step, which I consider to be the art side of astrophotography, will go much smoother. This will help ensure the tracking is more accurate during imaging. To get the best view with your telescope, you need an unobstructed sky. I could get an 8" one that does track, but as some of you have already said taking pics wont be as good with it than with a scope using an equatorial mount (and apparently the 2 inch difference has a large effect). some (Video) imaging possibilities. To begin the alignment, I turn on the Sky Commander unit and enter the date. Once I know the subject is centered in frame, I adjust my camera settings to the values I want to use on that object. Say EQ6 as a start. The next thing I do is slide the counterweight around on the back of the mirror box until the scope is evenly balanced when pointed at the approximate altitude of the object that I'm attempting to image. This is the same reason why you can see miragey-looking wavy images over hot pavement. The choice is never easy? Otherwise, the stars in the photo will appear streaked across the frame in the direction of motion. And if lucks on your side, you can even see the surface features of Mars along with the belt of Jupiter. At this point, I usually pull the scope out into the driveway using wheelbarrow handles that screw onto the side of the rocker box. On your setup that you've posted a pic of, what imaging equipment are you using and is the backfocus the more common 55mm or is it different? Several functions may not work. Basically, youll learn to find the right constellation and clusters easily. Realistically, a 10 inch Dob is poorly suited for astrophotography. Afterall, Dobsonians are very affordable, have great light gathering abilities, and many amateur astronomers already own one. Both encoders are hooked up to a small computer unit called a Sky Commander XP4. Human eyes don't detect infrared light, so for normal daytime photography, you don't want the camera to detect it either. As for choice of dobsonian, they are both quality instruments. It's difficult to take photos of this so I labeled the picture below. For example, you can see the Proxima Centauri; our closest star shining 4.25 lightyears away. I have a ServoCat and wouldn't fancy trying to set it up for long-exposure AP. With the addition of my new modified camera, I should be able to pick up much more red signal in my 10 second exposures. Many galaxies will reveal their spiral .

Mind you, this is only half of the process that goes into creating deep sky images. So, before buying anything based on a hunch, you should seek out some opinions about quality sky atlases. My telescope is a basic truss tube style Dobsonian scope thats constructed mostly of plywood with a few specialized metal components and electronics. It's easy! My scope has a total of 7 fans that all run off the lithium battery pack. Manufactured from solid aluminium and powder coated to resist corrosion and maintain appearance for years to come. Sign up for a new account in our community. When focusing a telescope for visual use, you simply use your eye to tell when the target becomes the sharpest. Get to know more about us here. So, before buying anything, make a plan for that. One possibility is an equatorial platform, they track for more than an hour before they need resetting,. Stars of magnitude 12.8 and fainter become much more clear. Objects within our solar system (moon, planets, asteroids etc), Celestial bodies (galaxies, clusters etc). The IntelliScope's Object Locator can also take you on a tour of the best sights to see in any month of the year. 12 Dobsonian telescope comes with a big price tag. (I have a 10' Meade Dobsonian) - Quora Answer (1 of 12): Most objects that are photographed in the sky are known as a deep sky object or DSO for short, and those are the ones that your Dobsonian will needed extra help. Plus, you get to see faint stars and clusters. Absolutely, if you are thinking of taking stargazing seriously. DSO AP with a Manual dob and 1 second exposures? This mirror, called the secondary mirror, sits tilted at a 45-degree angle to the axis of the telescope tube. These light weight, compact, medium payload titans will deliver an astronomy experience like never before. Thanks for all the advice guys!!! A smaller DRIVEN Dob - with e.g. If you are lucky, you can see many faint comets and asteroids. But the scopes that most GEMs can carry accurately, are quite small in diameter compared to a larger Dobsonian like mine. I have constraint of space in my room and carrying the scopes via stairs at least 2 floors for setup. VIDEO imaging out of hand As a viable, alternative, *REAL*, possibility for DSO imaging. of 1 inch barbell weights. Although it is heavier than their cousin, you can watch more with it. On my scope, these tools include a powerful green laser pointer and a Telrad finder, which basically functions like red dot optics for firearms. I cut my mask out of rigid cardboard using a vinyl pattern that my wife made with her Cricut cutting machine. Apertura AD10 on equatorial platform ZWO ASI 485MC ZWO UV/IR cut filter. So, lets take a look-. By using this site, you agree to our Terms of Use. Azimuth roller bearings and adjustable altitude trunnions provide silky-smooth telescope motion. Stargazinghelp.com is a knowledge hub for professional and amateur astronomy and astrophotography enthusiasts. For example this one ngc891. Generally, the higher you crank up the ISO value, the noisier and more grainy the image will be. Even with the swish new tracking dobs it ain't going to happen. Those are. It houses the spider and the secondary mirror, along with the focuser and various tools for aiming the telescope. Dob owners might consider VIDEO astronomy. Ill be doing planetary . The SkyLine 10" Dobsonian telescope features a machined, 2" Crayford focuser with dual-speed adjustment control and smooth, backlash-free motion. Ernesto.Nicola and matt_astro_tx like this. Then there are 4 fans mounted to the inside corners of the mirror box and blow air directly onto the front surface of the mirror at a low velocity. Planetary imaging with a dobsonian is fine. The image below is a single 10 second photo of The Orion Nebula (M42) straight off my camera with no stacking or processing. Coupled with (say) an 8-10" Dobsonian, you can display 16th magnitude stars on a screen in REAL time. A coma corrector is an extra optical component that sits between the telescope and the camera and corrects this issue before the light reaches the sensor. Astrozap Dobsonian Eyepiece Trays. I should also mention at this point that I had to design a special device on my scope to add some friction to the side-to-side (azimuth) motion because it was too loose to properly line up a star or view by hand. You can even see the ring split of Saturn through 10-inch Dobsonian! This could be due to poor tracking, bumping the telescope, or other issues such as a satellite streaking across the frame in the middle of an exposure. The good ones are not cheap but they can be made in a workshop. Converting the Paracorr II for use with my camera required an adapter (Televue part no. There is a different part number for the Nikon version of this adapter. Powered by Invision Community. The visual viewing is great and you will see millions of stars through it. I push the button to run the program and then I can walk away while the camera takes that exact sequence of photos. This may seem like an obvious next move, but I felt it was important enough to warrant its own step. Light enters the end of the telescope tube and bends, or diffracts, slightly around the metal vanes of the spider. Or a bigger Dob with greater visual potential etc. Field rotation is the apparent rotation of objects in the scope's field of view, either through the eyepiece or on your camera's sensor. But, if you want something thats really versatile, this is the one to go with. My scope has a focal length of 2000mm. One last question, would the 10" be hard to use because of it's weight? An easy way to visualize field . Even while living in the city, you can expect to see the bright stars with this telescope. As with all Dobsonians, the optical design is that of a Newtonian reflector consisting of two mirrors. The answer is yes. It depends on your choice. It features a primary parabolic mirror that is precisely placed to eliminate any spherical aberration in the images. This is simple and intuitive for beginners when compared with more complicated mounts. During the stacking step, the individual frames are also combined with various types of calibration frames, designed to eliminate extra signals that the camera sensor picked up. To slide it around, I simply loosen the plastic knob on top. After lining up the second star and hitting enter, the Sky Commander unit knows where the scope is pointing at all times. Here is a picture of the Moon from a 6-inch Dobsonian : However, to take things to the next level, you should consider taking a filter or two. Then I move the focuser in and out until the diffraction spikes created by the Bahtinov mask match the image I showed above. However, do remember what we said before. For this, you can enjoy the amazing bright nebulae from a dark site. This Dobsonian telescope is a specialist for deep sky. Description Video Specs Warranty Manual This is a Generation II telescope. The most obvious would be my camera, which is a Canon 6D full-frame DSLR.
