Three more DSO's

Beautiful open cluster NGC 6124 in Scorpius, located 18,600 light years away. First time I've imaged this. What a nice cluster it is with fingers of dark nebula running through it. Takes a lot of time to image this one, unlike M7. Taken over 3 nights.
222 x 30 sec subs, 8" F4 Newtonian, Baader MPCC MKIII, Heq5 Pro unguided, Pentax K-5. Bigger at Astrobin. http://astrob.in/173579/0/

Not sure why I imaged this. Something to kill time between other targets? NGC5897, discovered by William Herschel in 1784 in his 19-inch f/13, this small, obscure globular cluster is one of the few deep sky objects of note in the constellation Libra. Herschel recorded NGC 5897 as "a very close, compressed cluster of stars 8' or 9' in diameter, extremely rich, of an irregular round figure, a little extended. The stars are so small as hardly to be visible, and so accumulated in the middle as to look nebulous." 19" F13!

120 x 30 seconds with the usual setup.

I think galaxies near bright stars are cute. This galaxy is NGC5102 near a bright star in Centaurus. It lies almost half way between M83 and Centaurus A. Discovered by William Herschel in 1835, at a distance of 12 - 13 million light years.
Taken over two nights between clouds. 112 x 30 seconds. 8" F4 Newtonian, Baader MPCC MKIII, HEQ5 Pro unguided, Pentax K-5.

I like galaxies as well. They often need a lot of FL though. I need a bigger gun.

I know why you imaged NGC 5897 - because it looks flipping great in your image! Really sharp and lots of nice colour. Great stuff.

Thanks all. 5897 looked better in the images of it I googled. I think I wanted to see how close I could get. No where near the 14 inch capture with CCD.

You could use a quality 1.5x or 2x Barlow, although obviously your
subs would have to be significantly longer.

Nice work Kevin, that K5 is doing a great job for you.
Do you shoot RAW or jpeg, that's a lot of images to stack.

I've never had any luck with barlows on DSO's Ray. I don't think my DSLR like high F ratios.

I shoot RAW (DNG) Ken. Yes a lot of stacking. Takes a while but the extra bit depth is worth it. I took over 16GB worth last night!

Thanks Dunk!

More great images Kevin.
I don't do many open clusters - but I've been doing a few recently. 6124 looks like a good one.

Tony.
