Hi,
I've been playing around with this image of Corona Australis (http://www.astronomyforum.net/wiki/Corona-Australis) for some time.
This is the best rendition so far.
What I'm happy with, colour, contrast and composition.
What I'm not happy with, stars and need another couple of hours of data.
Still it's my deepest image to date shows a couple of PGC galaxies, mag 14.7 and 14.9.
Equipment.
8" Newtonian astrograph f/4. on HEQ pro 5 mount. Orion (http://www.astronomyforum.net/wiki/Orion) mini guider.
Unmodded canon 1100D, baader coma corrector, cooler box.
11 x 10 minute subs, darks and flat frames applied.
Median stack in DSS (http://www.astronomyforum.net/wiki/DSS), processed in PS7.
Cheers,
Justin.
