Object: Messier 31 (NGC 224)Type: Galaxy
Distance: 2.3 million light years
Constellation: Andromeda
Date: 09 December 2006
Equipment: SXV-H9, Soligor 200mm telephoto lens
Subframes: 50 x 90 second full frame (unguided), 16 darks, 16 flats/flat darks, calibrated and stacked in AIP4Win.
I was quite pleased with this although the brighter stars are a little bloated and have halos - I don't think the lens is a particularly good one with respect to chromatic aberration. It may be OK on narrowband or with colour filters. I'll get around to trying this one again using a filter wheel.
