EdgeHD 14 and FLI Atlas with mirror locked
Does anyone have experience with locking the main mirror of the EdgeHD 14 in the transport position so that it does not move during a long imaging session and using the Atlas for focusing? I expect that the 146 mm distance from the back plate to the imaging chip would be lowered by the amount that the focal plane moves when the mirror is locked back into the transport position. So, how far is that and would it leave enough room for an adapter between the back plate and the Atlas and provide a flat field across the whole image?
