Post by: JohnP on Oct 18, 2013, 13:01:57
Below third image from trip last week - The Cave Nebula. Again, need to get some colour for this. Details ED80 + Atik 314L+, 7nm Ha Baader. 17 X 600 Secs. I took this late Thurs night going into Friday morning which for those of you who were out there with me (Fay & Robert) will remember it was very windy & 'ing cold. Ended up with ice on laptop.

Cheers,  John

It looks great!

Round stars with lots of detail and contrast.  I can't believe it was cold enough for ice to form!

I bet you're glad to be imaging again - fun, isn't it?

Hi Chris,

Agree with your comments. The cave is actually quite a dim, diffuse nebula & hard to process so I probably pushed it too hard & hence the noise. The below image is with a 'smidgen' more noise reduction (perhaps too much - my eyes are all screwed up now from looking at monitor too long)..

Yes you are correct that's the night you 'wimped' out or rather drank too much single malt & feel asleep on the sofa watching Avengers...!!!! :-) :-) :-)

Cheers,  John
