It sounds like a very unusual way that you have processed the image but it has certainly brought out the star and neb colors nicely...
Another fine image!
cheers Gary
Thanks Gary. Its a rather busy scene making it visually congested (in my opinion). Still fun to image though. The original frame appears more pleasing (compared to this crop) as there is more "blank" areas that give a better sense of object/spacial distance. Not sure if I'm onto something with the new processing flow - time will tell. Thanks again.

love the resolution to and pin point stars
Hey Col. Haven't seen you around here for a while. Pleased you like this image considering its at your "neck of the wood" in the Northern Hemisphere. I've read reports that visually detecting the Bubble is quite difficult and is likely to require filters. I hope you get to track it down mate. Though those winter nights are approaching.

Yes the cluster looks great, but it's the Bubble Nebula that catches my attention more. Sorry about that, but I find the Bubble Nebula drawing me in.

Great work, and again nicely presented and helpful information.
Thanks Ken. I do agree, the bubble is quite a show piece, but I feel Messier 52 holds its own. I like that its a wash in other Milky Way stars, subtly resolved and defined. Thanks for taking the time to check it out.

What length subs did you use???
Cheers Lee. Subs were short in this image - only 5 min. There is reasoning behind this. Longer subs can cause issues with star bloat if not managed correctly. It can be processed this out later, but at the expensive of star colours. To circumvent this in the past, after taking 10 or 15min subs for nebulosity details I take a few shorter subs through individual colour filters which I use as a star only layer in PS. I then combine the two to achieve an aesthetic image. A lot of work, but the results speak for them selves. No one said imaging was easy right? Thanks again for your comments.

Hi Glen, the image was acquired from a robotic internet telescope under the pristine dark skies of New Mexico. At 2,225 meters above see level, seeing conditions regularly reach a FWHM of ~1 arcsecond.http://www.global-rent-a-scope.com
There is something special about remote imaging. Technically, I can image 24x7 as the sky is dark somewhere in the world. You still need to plan your targets carefully and determine composition, exposure times etc. The image processing components are no different to using your own telescope - its still very challenging. In fact, my own observatory is also remotely controlled so I merely see this as an extension to my imaging goals. Thanks for checking out the image.

Thanks for all the info on your capture and processing. At some stage this will all sink in and become useful in my own exploits
Cheers Mike. I concur, the M52 open cluster gives an interesting focal point, but like the others indicate, its hard not to focus on the bubble. Re: processing - give it time and more importantly take your time. I spend hours processing a single image until I'm happy I've maximised the most from the acquired data. Don't be afraid to experiment and read/glean as much information on image processing as you can. Being methodical can assist. Thanks again.

Ken is right, the Bubble really does draw you in.

Top stuff.
Thanks Ric. Indeed the stars are pin point sources of light, but they weren't that way originally. Required some work to get them looking cleaner, but not crunchy. Can't say much more about the bubble, its great. May target it with a longer focal length sometime. Pleased you liked it!
