Hi all I took this image on the 12th Febuary with my skwatcher ed 80 and stacked using deepskystacker and used new software to get rid of the light pollution.I thought I would share the test shot,thanks for looking.

What was the light pollution software?

You have some nice colour there. Is this just the stack or have you processed it?

Regards

Graeme

Its a great object to look at with any kind of telescope and very rewarding to image. It's a nice sharp image with a lot of detail. I think you could increase the colour saturation a bit more. Also try shifting the 'hue' value by 10 or 20 points. It will convert that pink cast into something more interesting.

What a shame that Orion is on the way out!
I use an 11" reflector (Celestron CPC 1100) and a 3" refractor, (Sky-Watcher ST80) mounted on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI 120MM, ZWO ASI1600MC and Canon 1300D for imaging.

Hi Graeme the light pollution software was prodigital software astroflat pro and works with my adobe cs2 photoshop as a filter plugin and is made up of 36 images and taken with my gpcam290c.
Thanks

Hi Aratus I increased the saturation and the hue to 20 and this is what happened to the image,it is a shame it is on its way out.I haven't had enought time to experiment with different equipoment.

I've taken some images of M42 with my gpcam290c last week and I've been experimenting with different software. My note taking skills need to improve because I can't remember what packages have given me the results I have got! Some are just monochrome and the colour has been lost, some are only green! The original images are under exposed so the end results are too grainy where I've over stretched them but the trapezium is clear. I use SharpCap to take the image and then I've tried DSS, Autostacker and Registax to stack them. I use Gimp to process them.

Here's one attempt!

Hi Graeme I use altar astro software and use the white balance and alter the black level to 200,then take images between 2 and 5 seconds.There is a manual on the Gpcam 290c saying how to get rid of the green on the image as it is has two green channels on the Sony chip.I like your image.

Cheers!

I read the altairastro thing on green cast removal. Turns out my green problem only applies to files saved in RGB like a bmp or png. I've been sticking with RAW files now because I read it gives you more scope with the processing. So whilst green cast won't be a problem now, my RAW files are all monochrome and I can't remember how I got the colour into them! I'll go play with Registax and Gimp again. It's all good practice until the clouds clear!

Congratulations on getting the trapezium stars separated!
Have the RAW files been 'debayered' to get the colour information?

Yep! Using PIPP I managed to work out that GBRG is my Bayer configuration. All I need now is a clear night to get some better quality data to play with! I might do some more M42 before it sinks into the western horizon. Perhaps we should all have a go and turn Andy's M42 thread into an M42 appreciation thread!
