A beautiful clear Moonless night last night meant I was up imaging until 2:00 a.m. – ah the joys of deep-sky astrophotography.
I put the M25C OSC on the back of the Canon 200mm prime lens set at f#4 and took 20 subs at 5-minutes per sub in the Kemble’s Cascade region.
Kemble’s Cascade is at a funny angle as I just started imaging where I dropped the lens into the holder, no alignment done. The light patch centre-left might be some light leakage – I have now covered all joint regions with Aluminium foil. The M25C is of course great at picking up the red stuff (unlike the Canon 5D MkII) and I took some out of focus images of NGC7000 which looked promising for future work.
Like any new imaging system it will take me some time to get used to it and to get the best out of it, but I think it looks promising enough for the time investment. I don’t think it looks promising enough to go the whole hog and base another mini-WASP rig on these lenses with CCDs though.
