Just thought I'd chime in here. I'm about to mod a 450D for astronomy only duties and intended to remove all the filters (aa and uvir hot mirror.) I do however intend to image primarily with my 300/2.8 (nikon mount with adapter focused via home made ascom stepper focuser.) lens. Will I not be able to reach focus with this setup? I will also be imaging with my 5" newt a bit..
My other intention was to get an astronomik clip in ha filter for imaging in the suburbs.
Anyone got any tips or advice.
