Hi all,
A nice little galaxy from tonight.
NGC 5247.
25 x 5 min exposures.
ST8-XME @ bin 1x1 @ -20
12" SCT @ 2200mm FL (f/7.4)
100% sized file at my website here (http://rogergroom.com/wp-content/uploads/2013/04/NGC-5247-25-subs.jpg) (too large to upload at IIS).
I'm quite pleased with the result.
Roger.

That's a great shot Roger.
I imaged that myself extensively about 6 weeks ago (an unprocessed shot). That is a very good high resolution image. Its quite faint and quite small. I was clicking through galaxies on the Sky X and the photos and thought it looked good.

I imaged 5247 about a year ago. I am really surprised so few people seem to image it - its got a nice look to it!
Good work! :)

That's a great shot Roger, at a high image scale too - well done! :thumbsup::thumbsup:

Thanks,
I was clicking around the sky in TheSkyX and found it in a similar way :) Thought I'd get it a crack, and here we are!
Lots of gems out there people forget about aren't there :)
Thanks :) Funny you know, a few years ago I would've said the image scale was normal, but now with so many productive setups consisting of high quality refractors of much shorter focal lengths, and much better quality focal reducers available, less people seem to be imaging 2000+ mm.

A nice catch at magnitude 13.5.

Great shot at that FL Roger. Tidy guiding. :thumbsup:

Thanks :) .. but I get mag 9.9 ? :shrug:
Thanks :)
I was happy with the guiding ... after aligning the images there was one pixel of gap around the edge where a couple (or more) of the images had to be aligned by one pixel :lol:

Hi Roger,
Wiki says 13.5.

Wow, that's quite a different value to what TheSkyX reports!
Considering how easily visible it is in a 15" Dobsonian I would have expected it to be brighter than 13.5 .... but I can't comment on the accuracy of either other than that :shrug:

Here it says
http://dso-browser.com/dso/info/NGC/5247
10
Stellarium says 10.5
Here:
http://www.kopernik.org/images/archive/n5247.htm
10.9
It looks like there is a bad error on Wiki.

I just went in and edited the magnitude on Wiki to 10.5

Good on you :thumbsup: I've never looked in to how to edit Wiki.

Yes - the actual link for (1) gives mag 10.5.
It was just a Wiki typo.
Tells me how I can't trust Wiki anymore -
at least it can be edited.
Anyway - still a great catch at mag 10.5 - that is dim.

Thats awesome Roger, such a faint distant object :thumbsup:
Call me "old school", but checking a hard copy of "NGC 2000" - it says that NGC 5247 is mag 10.5. :)
Books... gotta love them!

Very nice image.
I remember imaging it with an ST-7 and C11 many years ago.

Lovely Roger!
I have been collecting data on this for a few days (between clouds) and was going to post it but you beat me to it!!
Cheers
