Hello. Long time astronomy fan, but new to cameras and astrophotography.
Learned how to change settings, (shutter release w/out lens, ISO, exposure time), but am struggling to get a sharp focus. Stars and planets are blurry.
Canon EOS M100 attached to a Meade LX90 (8" SCT/ 2,000mm focal length).
Any suggestions would be appreciated. Thanks in advance.
I attach with a T2 EOS-M and Meade #62 T adapter into the scope. Using the telescope focuser hasn't gotten images sharp, but in my reading, I have seen I may need to use a diagonal or slide the adapter out a little (tighten with scope's thumb screw) to add a little more length. Cloudy tonight, so will have to wait for next, clear night.
The distance from the back of the Celstron and the camera focal plane is critical. It has to be correct or you will not be able to achieve focus (infinity). There are adapters that are designed to position your camera's image plane at the optimal distance. The focus adjustment built into the lens may not be sufficient if that measurement is not correct as you have seen.
