Celestron 93635-A Overview

Ultra telephoto photography is easily achieved with your telescope by purchasing this SLR camera adapter. You'll need to take precautions to minimize vibrations, such as locking up the mirror if possible as well as using a cable release or remote control to fire the shutter.

First, remove the eyepiece. Next, attach the SLR camera adapter where the eyepiece would normally be attached to the telescope, and screw in a t-mount adapter to the opposite end of the SLR camera adapter. Now you can attach your camera to the t-mount and you are ready to begin taking pictures!

Your camera will need to be in fully manual exposure mode, although some brands of camera may also work in aperture-priority autoexposure mode.  Additionally, if there is a switch on the camera which chooses the focus mode, that switch must indicate manual focusing.

Does anybody knows if this adapter works with the Celestron Nexstar SLT 127?
Asked by: Mauro
Yes it works fine. Make sure the threads are snug and use the live view on your camera to focus the frame and use a shudder release cable. Good luck and shot!!

Does this work with the Celestron Nexstar 102 mm GT?
Asked by: Sherman
Hello ShermanI don't know. I bought this for the Nexstar 4SE. My advise is to call Celestron. You can get the customer service number from their web site. Good luck.

I have Celestron Nexstar 4SE. Does the front end (mounted on the telescope) of this adapter extend forward like in the pictures on the internet ? Also, does the back end fit to the Vello T to Sony E mount adapter ? Can someone check this ? Thanks
Asked by: Yıldıray
I have a very old Celestron C90 (over 20 years) it drove me crazy trying to put this on my telescope until I realized the threads were different. Like your Nexstar my C90 has the lens mount centered in the back of the scope, if there is an externally threaded pipe you're probably in business. Yes the front end of the device has a collar that extends and threads over the pipe. The other end attaches to a specific camera mount e.g. Sony A, Canon EF, etc. I think its easiest to attach the ring to the adapter (I leave them together all of the time) then to the telescope and lastly mount the camera to the mount like the whole Nexstar is a giant camera lens. I can't guarantee anything but your setup looks like mine and that's the way it works. BTW I've gotten some really nice results using a device that holds your camera lens over your telescope lens. It actually works well, but you have to spend a lot of time lining things up. There is also a similar mount for smartphones using their cameras. Remember that the moon is brighter than you think it is. I use shutter preferred mode with my Canon for lunar photography. Lastly some people run short movie clips of stellar events and then process them through stacker software for great results some times (a collection of stills can do the same.)
