Hi all
Was up till 4:30 am imaging last night, temperature was comfortable, sky clear albeit hazy, seemdd quite light, but was stoked to get the best ever NGC253 pic Ive taken, a full hour on it. I started when it was right at the zenith. 6x10 mins ISO 200
I also re-imagged the Grus galaxy grouping Id done previously, this time fitting in all 4 of them, including NGC 7552 at lower right
4x10 mins ISO 200
Darks, flats, offsets processed as usual in IRIS, adjusting dynamic and colour stretching to get the faint outer details while not over exposing the inner bright parts, then finishing off in Photoshop.
Digital SLR's never cease to amaze me, the sky was so light that I could barely see the LMC even at 4 am when it was near its highest, yet can pick up the galaxy detail it has
Both images shot with 10 inch f5.6, off axis hand guided (gee it was a long session lol),IDAS uv/ir filter and MPCC used, on modded 350D. Some light to mod. gusts of wind but as it was coming from the NW I was protected by trees and the house and fence, VERY dry, no dew at all. If Id had Strikers cooled camera I could have wound the cooler to full without condensation
