Hello all, with pleasure I found some exposures did last year ! The conditions were not very good but I decide to process it ! Object : NGC7538 Common name...
Hi Friends. I am waiting for a Starlight Xpress SXVF-H9 camera to use with Astronomik SII, Ha and OIII filters for tri-color NB imaging and have a few...
Yep, I would try to optimize each channel's data, including DDP, before taking into PS. The aggressiveness of the stretch is totally up to you. I strive to...
I took the shots for this image many months ago, but my processing skills weren't up to the task. John Ebersole took mercy on me and provided a lot of help,...
Nice job of processing, John! I like it a lot! There is no green cast that does not belong. Background sky is black; the rest is nebulosity. Richard Crisp...
NGC 6357 nebula also known as "War and Peace" or "Lobster" taken from my backyard under suburban light pollution, it's about 5500 light years away, total of 17...
Good job, Eddie. I tend to prefer the more blue version, but in both I think there might be some gradient left in the red and a little less in the green...
Well done! Cheers...Neil www.flemingastrophotography.com Direct from Boston - brilliant diamonds in pea soup Also check out the astro_narrowband Yahoo...
Hi Friends. After studying Ken Crawford's video tutorial and Steve Cannistra's step-by-step tutorial on NB color processing using clipping masks, I reprocessed...
Nice job, Gordon! Personal taste, of course, but I prefer less orange and more of a reddish tone when doing synthetic green (sG). If you want to try this,...
Thanks for your comments Neil. I agree that there is too much orange. However... Here is an image of NGC 281 (Pac-man Nebula) using the same technique (also...
Hi All I managed to get out for some imaging last night to complete the first stage of my tri-colour narrowband image of this object. The sky was clear but it...
I think you'll find that OIII (of almost any width) will be subject to gradients. SII displays a bit of them too, and that is accentuated by the strong...
It's been raining and cloudy for weeks but it looks like the weather is starting to break here in NY. It finally cleared last night, but the moon was blazing,...
Hi Neal. Thank you for this information. These are probably dumb questions but I'm going to ask them anyway... Why is Ha data more immune to the effects of...
Hi All After doing the Ha data on this object a couple of nights ago I managed to get out again last night and shot 27x10 minutes for the OIII. The capture...
Hi Friends. Here is my first tri-color narrowband image. The target is NGC 281, Pac-man nebula. To view the image click on the link below. To see the image...
Thanks Doug. I tried to use just the Ha data for luminance but I wasn't happy with the results. I then settled on using the Ha data that I had combined with...
Hello all, I test my new guider system with MMOAG from Astrodon witch is customised by a friend for a good backfocus between IMG6303e and TEC140 (I have only...
Hello all I've been imaging for a while with my modified Canon 1000D. My imaging scopes are - Celestron C11 at f/6.3 - WO Megrez 90 with FF IV - WO Zenistar 66...
Hello Nigel, Have you modified your Canon and removed the standard internal camera filter? You will need to do that to increase the H-alpha response. I have...
Hi, All, I've been monitoring the list and see how much better all narrowband images are getting. Here's one recently taken from my remote, dark site with a...
