Cat's Paw May comparison

kosborn (Kevin) · #1 20-05-2018, 01:55 PM

Haven't seen many Cat's Paws posted but here is my attempt. This is a bit short on data (especially when I look on astrobin and see up to 12 hours of integration) but as always I'm impatient. Each night is a late start for me on this target as I have to wait for it to clear the 30m high tree in my front yard.

This was 20x 180s Ha, 2x 300s Ha, 13x 300s OIII and 15x 300s SII. All criticism (constructive or otherwise) welcome.

Cheers, Kevin

You have some nice detail and colour, nothing to be scoffed at

Way to go Kevin.
I think you did great for the time.
You know you are causing me grief...I am starting to teally want a narrow band looking at your images.
Whats making it worse I have had clear nights so I am beging to think maybe...but its still only an hour a night...it could take years☺
I cant get over the detail.

Good one Kevin

Thanks all. Looking forward to seeing other's examples. Alex, I'm really pleased I upgraded from dslr to the mono camera, especially because of the increased resolution/detail and the decreased noise. But it definitely needs more integration time and especially more processing time. Worth it though I think - it just means it's very hard to finish a target in one night.

Cheers, Kevin

hi kevin,

this is a great shot, i'd be happy as with this - well done.
you could bring the black point up a bit (levels) if you were inclined.

cheers

I'm not going to get "real imaging" of this, but here's a live stack I finished one minute ago.
80mm refractor on an EQ5 mount (onstep modified) - a bit of drift as didn't polar align.

ASI290 with Ha-filter. Captured, stacked and adjusted histogram live in Sharpcap. This is a screen shot - 26x 12sec (~5min total).

Looking good. Don't make my mistake and stop too soon. More data!

Cheers, Kevin

Polar alignment was so bad it would have dropped off the screen after 20min!!
There's always a fine balance between getting a nice shot and boring people to death who are watching your broadcast.
