We'll be Counting Stars...

Hi all,

In addition to the big scope & mount I also took my 35 year-old Vixen SP mount away with me on last month's dark-sky trip.
One night I set up my old DSLR and 135mm lens on the Vixen and let it run in 'set and forget' mode whilst I went back to imaging with the ZWO/MN190

It's one of the richest regions of the Milky Way and no doubt well known to most here. I managed to fit in the Lagoon and Trifid, as well as the Sagittarius Star Cloud along with IC 1284 at lower left and open cluster M23 at top left.

40 x 90 sec subs at ISO 400 and at f2.8 tracked but unguided.
Astro-modded Pentax K-5iis and Samyang 135mm ED UMC lens.

The high-res version (HD) is here: astrobin

C & CC welcome as always.

Pete

Impressive. The stars are really well resolved. Always good to see these objects in perspective.

Nice Pete, a very pleasing wide field.
I canít get it out of my head that the Lagoon looks like Homer Simpson.

Thanks Marc! It's a tried and tested imaging combo but as my attention was elsewhere I wasn't sure how it would come out.

Thanks Peter. The lens works really well but correct focus is critical.

Oh yeah - I won't be able to unsee it now, Doh!

Cheers Mike! Happy I can now run this combo semi-autonomously as long as I take care during setup. The nights I get under proper dark skies are few and far between so I try and make the most of it.

Thats really nice in AstroBin, Pete, I can see finer details compared to my full-frame with larger pixels & the same lens, I'd need near 200mm for that field, & a fast prime are way expensive, I might consider a RedCat down the track but doubt the startracker would do it justice...
Awesome Image and grouse to see for sure

Thanks Bob!

The Samyang/Rokinon 135mm lens has becom so popular there is actually a group on Ast boon dedicated to it.
Plenty of photographers have connected cooled astro cameras to it. Might eventually try connecting my ZWO 2600MC to it one day.
