    Default 40D with Nexstar 4SE mounted

    All you need is a Canon DSLR T-Ring and a Celestron T-Adapter (Model 93635-A). You can find both on Amazon.com. The T-Ring screws into the 40D on one side and the T-Adapter on the other side. The problem I am having now is that the camera is too heavy and causes the whole telescope to swing upwards!! Does anyone know how to counterweight a 4SE? If you want to check out what the setup looks like and the results..see my photostream on Flickr (same username).

    To tell the truth, I was excited to try out this setup for some time..but when I finally did get all the pieces together, I find I am only capable of taking nice moon shots. It seems that the Nexstar 4 SE is just too small to take pictures of anything but a few planets and the Moon with an SLR. Has anyone tried the tele-extender with the 4SE?

    Another option, which I have not tried, is to buy the Neximage camera..which is simply a webcamera with some neat software. This camera can sit on top of the barlow lens and you can double your magnification. The software will take multiple shots of your target and stack them for a really nice picture.

    Hope this helps somewhat.

    You need a Canon T-ring and a T-Adapter(Celestron model 93635-A) but I have to say it doesn't work as well as you might think. I just put this together and found that the 40D is quite heavy and causes the telescope to become unbalanced. I haven't found a way to counterweight this yet. I am thinking of strapping some small sand bags to the front of the telescope..seriously.

    This configuration (T-ring and a T-Adapter, 93635-A) works well for me



    The other way is use Barlow t-Adapter 1 1/4 inches (93640) and Erect Image Diagonal (94116)



    There is other variant



    In these cases you can find balance easier.

    I also have a Nexstar 4SE. You will be able to take some good shots of more than just the moon, trust me. I have taken several decent shots with my camera phone being held up to the eyepiece.

    Check them out here, if you'd like:
    Astronomy Forums | Telescope Forums & Reviews | Astronomy Community - Cladinator's Album: Jupiter 2010-08-12

    When you have all your gear in order I'm confident that you will be able to make some good shots.
    As far as the balancing problem, I do believe there is an option on the scope that allows you to balance it. The camera setting may also have a way of compensating for the extra weight. I'm not too sure though since I haven't used the scope in this way.
    Best of luck and have fun.

    Adding a t ring and adapter plus a DSLR and focal reducer is a lot of weight for the 4SE mount. The 4SE mount's altitude clutch is rather weak and can slip unless the scope with its accessories is balanced on the mount. The problem is that the 4SE's dovetail is too short to achieve a balance. To solve the balance problem, I bolted a camera vixen dove tail to my 4SE using the tripod mount screw holes on the scope. This allows me to easily balance the scope. I also got a SCT adapter to screw on the back of my 4SE to allow me to use all my SCT accessories on the little MAK.

    However, photographing DSOs, even with a focal reducer, is a challenge with the 4SE OTA because of the very long exposure times required. It's doable but you end up with a lot of exposures to stack. For photography, I don't use my 4SE OTA but my 4 inch Meade 2045LX3 SCT OTA with a 6.3 focal reducer instead as the camera scope. The difficulty with the 4SE OTA is its long focal length vs its aperture. This is not a show stopper but, in my case, my 4 inch SCT bolts directly to the 4SE mount so why not make life easier.

    The 4SE mount, on the other hand, is very useful for photography. The tripod is sturdy and the mount's tracking error is not that bad ... after a slew it needs a couple of minutes to really dial in before you start photographing. In the azimuth mode, 30 second exposures are obtainable. After a long search, I finally got a "firing cable" and can now let the 4SE's handset control my DSLR (Canon EOS 1000D/Rebel XS). The handset control of a DSLR makes life very easy; program it and then let it do the work for you while you do something else.

    At the moment, I am attempting to accurately polar align my 4SE mount in the equatorial mode. Not mentioned in the owner's manual is the fact that since last year Celestron has shipped the 4SE with its All-Star Polar alignment module programmed in the hand set. This feature is supposed to provide an accurate polar alignment and is the same routine used in Celestron's more expensive mounts. The difficulty with the 4SE mount is that it has no fine azimuth or alt adjustments needed to dial in the alignment so a lot of trial and error physical movement of the mount is required and getting an accurate alignment is a matter keeping at it until you luck out. For a precise polar alignment, modifications are needed to the mount.

    I also use a SkyWatcher SynScan AZ goto mount for photography. In the azimuth mode it is capable of 15 to 20 second exposures (there is no equatorial mode on the mount) The SkyWatcher mount is rated at 2 pounds less (~1 kg) than the 4SE mount but I find it far more robust and never have experienced a problem with slippage with its altitude clutch. It can carry significantly more than 8 pounds ... I have an 8 inch Meade LX200 OTA on mine that I use for viewing while the 4SE mount is busy photographing away. The SkyWatcher mount has no problems with the weight of this large rather heavy OTA. I did extensively modify my tripod to beef it up.

    Exclamation Re: Canon EOS 400D

    Everyone here is replying about the 40D, which is a heavy camera. but the 400D that the thread starter has mentioned is not a heavy camera. i have a 450D and its only slightly heavier (if i remember correctly) and its not too heavy
