22565RE: GTF81 focal length
- Mar 4, 2014I use the GTF81 with an Atik 383l camera. What really cinched it for me was that it was becoming difficult to fit all the components of my optical train using a scope with an added field flattener/reducer and not search all over creation for the bits to get all the spacing right. With the GTF81 (and the GTF102) this is not at all a concern. The optics are sharp, the field is pancake-flat, and I really like the feel and strength of the focuser (I don't use the DDG version).Attached is a recent image I did using that pair.
