We are new to astrophotography.
We have a Meade 16" and are using a modified Canon DSLR Camera. We are in a situation where we need to use an altitude azimuth setup. We would like to take some 15 minute pictures and have purchased a Meade field de-rotater.
Once we get the field de-rotater, the micro focuser, a 6.3 reducer, an off axis guider and a T-mount in front of the camera, we have quite a long setup.
Here's my questions:
How far can the camera be back away from the telescope?
How far from the focal reducer does the camera neet to be positioned?
If the camera is to far away do we loose resolution - light etc?
There are probably other questions that I need to ask. Can someone help us?
