Double Cluster from sept 5th 2014


Recommended Posts

As you might have seen I've already bounced this one a few times in the forum (and on swedish Astronet) to get some feedback. And I don't think I'll do anything further with it, so here is the official version! 

Since I don't have a backyard obsy it's always a struggle quickly hit the road out to a darker site with my gear whenever there is a reasonable gap in the clouds. This time I also had to throw away half of the subs because focus crept off slightly mid sequence. In the end I got about 39x30sec subs at ISO800 (timer remote I bought last week was faulty),16 flats, 40 bias and 1 dark (I thought I took a sequence, but I took a single by mistake).

This is the first time sucessfully using T-shirt flats. There is a slight gradient left, but that could possibly be LP from the airport.

The yellow star color just jumped at me, but there wasn't really a hint of blue so I had to fiddle around to get the balance right, so color wise it might have slight hint of artistic freedom.

I've learned a ton reprocessing this image over and over, can't wait to get my hands on a coma corrector, guide solution, working timer remote and who knows, maybe an astromodded DSLR.

Thanks for looking.

Hey Carl, 


 


nice image! An easy autoguidingsetup is to use your 9x50 finderguider with a qhy5 camera and phd. The total cost of this operation will only be the camera and a piece to fit the camera to the finderguider. A cheap and fully functional solution. And you will also have a perfect planetary/lunar ccd:-)  I bought my camera and a c-mount adapter for ( right angled, make sure to chose the right one if you walk this path. ) finderguiders from Modern Astronomy. 


 


And regarding modded dslr´s. Check out Juans site; http://cheapastrophotography.vpweb.co.uk/ His Baadermodded 1100d seem good. There is also an option with JTW astronomy, but I have not seen any reviews from them.

Oh, and this is not meant as advertising, but just a tip on where to find parts, since I had to look for a while before finding what I looked for.

Thanks Erik, not sure yet if I want to lug around a laptop to run PHD. But I guess that road is more future-proof than a Synguider/Nexguider. I'm also undecided if I want a comacorrector or get a new frac instead...
