Continuing on with hunting for galaxies this week at my weekender on the south coast , captured NGC 253 an edge on spiral galaxy located in the constellation of Sculptor. With a brightness of magnitude 8.0 it is a great target measuring 22’ x 3.5’ and easily found with my 8” f5
Conditions for imaging were excellent ( no wind, no moon, no dew, low Jetstream, good seeing )
8”f5 Bintel GSO newt on an EQ6-R Mount
Canon 600D unmodded with Baader coma corrector
Home made 60mm cooling fan
ISO 800
30 x 5 minute dithered guided subs
20 x darks
Captured with BYEOS
Goto and tracking EQMOD, Stellarium Scope and Stellarium
PHD2 guiding using Hysteresis at 0.70 to 0.80 arc sec error ( even better than the previous night )
Stacked in DSS
Processed in Startools
Thanks for looking, comments always welcome
PS: I probably repeat my details each time I post images but I do that so folk who are just starting out in AP can see some brief astro technical info and what can be achieved in AP with just a budget Newtonian reflector, an old Canon DSLR and low to mid end mount plus odds and sods. I think most beginner folk go for the small refractor to start out with which is fine but don’t discard the newt even the 6” ( as Alex always mentions )
