Last night I used my new scope(TEC APO140) for the first time combined with my Canon D20, it was cold and I have not the bravery to take out my ccd camera and computer for a real guided image session. Anyway, I took several unguided frames of M42 with my APO140 through an Astro-physics 0.75 focal reducer to check for field curvature and I must say Im pretty happy with that! Just to do something I took 50* 40secs unguided frames of m42 and used Maxim DL/DSLR 4.51 and Photoshop CS2 to elaborate them. Nothing special but Im happy with the field correction Ciao Max Baravelli Bologna
