two out of three aint bad!

[alocky]

I had to give up on my attempt to fit all three of the leo trio into a 2 frame mosaic as the light-pollution gradients just killed it. However, each of the two frames wasn't so bad with a bit of cropping, so here's M65 and M66. It's certainly possible to see the bar in M65, and the internal structure of M66 shows that these guys have had a pretty hard time in the last 800 million years.

Scope was a 16"f3.6 with Wynne corrector, camera is a QSI683wsg with astrodon filters. This about 3 hours of L in 5 minute subs, with 1.5 each of R,G and B.
Constructive criticisim welcome, as is speculation on whether or not I ran decon on the luminance channel.
cheers,
Andrew.

Nice one :thumbsup:

[atalas]

Yep nice work Andrew :thumbsup:

[Placidus]

Trish: Gorgeous!
Mike: Subtle and beautifully processed.

[RickS]

Nice detail, Andrew!

[Atmos]

Very nice noise free detailed image Andrew :)

[Ryderscope]

And a fine pair they make as well. It’s nice to be able to peer into the structure of the two galaxies.

[Camelopardalis]

Nice one Andrew, a little more detail there than my 4” ;)

Hope you mosaic the hot dog in...

Shame about the damn gradients :mad2: but a great pairing Andrew. I like images that just show these two more than those that show all three. Some good detail showing too :thumbsup:

These things are at a fairly low elevation, so getting anything that shows good detail should be considered pretty good. Not bad for light polluted skies.

Thanks Paul - I'm 10km south of the Perth CBD which puts these things right in the light soup!


Thanks Mike - part of the problem is with any stray light getting into the corrector, the shadow of the off-axis pickup in the QSI camera changes very slightly against the flats. I don't even need the damn thing anymore! Unfortunately, this always wipes out the middle third at the bottom of the frame.

Not that much more, though! Best I can do is link in the other frame :)

Apparently, the concentration of quasars (which are among the little smudges above M66) is what got Harlton Arp thinking that maybe they weren't cosmological redshifts!


Thanks Colin!


Cheers Rick! BUt I wish for dark, mountain skies though. I'd love to see what this scope could really deliver.



Thank you both, very high praise from an extremely credible source!


Thanks Louie!

Cheers Peter! They go well with a Hot Dog. :P
