Markarian chain... well, part of it! (SGL7)

[Uranium235]

Here is another chunk of processed data from SGL7 at the main weekend. I had a chat with a few people to see what they were imaging and a few seemed to be heading for the Markarian chain in Virgo, so I thought I would have a bash too.

Little did I know its one of those targets where I have to rotate my focuser by 90deg. Well, I wasnt too keen on that so I decided to do a mosaic. Though it seems that two panels isnt enough with the 314 so I will probably have to add to it at a later date as Mr Moon is on his way back.

Not quite enough subs to make a big impact, but from dark skies its better than a poke in the eye.

2 Panes, 10x300(L) per pane

ED80(0.85), Atik 314L+, CG5-GT

Thanks for looking!

I am very impressed. This is a good photo! Look at all of those galaxies! WOW

Cracking Data from Sunday night with such dark skies is a real joy to work with, isn't it?

What happened to your 450s rule!?

[Uranium235]

As like a few other people that evening, my guiding decided to throw a wobbly and seemed to take ages to respond in DEC. So I dropped the sub time in order to get more useable subs.

Yesterday afternoon I discovered the cause of the play in my dec axis, the locking ring (where the couterweight bar screws in) was a bit loose. So I tightened it up and theres absolutely no play in it now, which was refelcted in the subs I got last night (round stars, more often). Still havent completely cured backlash, but its better than it was.

beautiful shot

[Uranium235]

Thanks Peter I might try to get that third and final panel tonight, but im back at work tomorrow so it depends on when it clears the tree next door.

Really great shot, amazing how many galaxy's are in this area of the sky was this done with the 80ED as well?

That's nice and deep, was that from Sunday night?

[Uranium235]

Yes Martin, that was from Sunday - which is why I didnt want to tamper with the camera orientation. RobH had lent me his flatfield panel just before sunset (I forgot mine... doh! so big thanks to Rob) and I did flats for the default camera position, but not for a rotated camera (didnt think I'd need them!).

QM: Yep, this was with the ED80. I also have an M101 and a coma supercluster from SGL7 that ive still yet to process - many fuzzies in that one as well as a couple of nice barred spiral galaxies.
