Description

The poster child of the sculptor Galaxy group again, this time with my new Meade 12in and 0.67 reducer.

Lum at 45s exps ~4hr
RGB at 90s exps ~5hr
Ha at 300a exps ~ 2hr

Taken over 2 nights of poor to moderate seeing. Still have to really refine collimation etc, but keen to get some imaging done in the meantime.

Interesting one here in that the two nights of data didnt really yield me a perceptible gain in image quality...maybe less noise.

Stacked and processed first in APP, then channel combination and process in Startools and blended and refined in PS.
