Hello all, When I have good subexposures and time to reprocess it I take some pleasure to experiment different palette, this palette is a classical Hubble...
fun image Nicholas, why do you attempt luminance with narroband images? do you think it offers benefit? If so what benefit and how does the data look if you...
last week I used the 300mm medium format pentax f/4 lens with my IMG6303E and custom Sci 4.5nm Halpha filter to image sh2-240 (simeis 147) this week I did the...
Yes, I noticed any sort of imaging including Ha near or during the full moon will never present the same contrast and faint details as without the moon...
Hi Richard, Luminance on Narrowband imaging help me to process separatly the colors layers and luminance layers. I had like to process on separate layers...
I went out to the ranch on Friday and imaged from there on Friday and Saturday nights shooting Halpha. I managed to snag 5h40min of SH2-240 in a moonless sky...
Hi all, If you can take some time to see this : http://www.astrosurf.com/nico-outters/astro/NGC6992%20en%20SIIHaOIII.htm There are some flash animations that...
Hi Richard, The no moon version is superb, and your new ranch is very nice, this area look like good for astronomy, and for the day you can can find some gold...
thanks Nicholas. The ranch will be a LOT of work, every time I go out there it seems there's another crisis out there: either a pipe springs a leak, the...
let's hear more of your method. I've been doing this for about five years and have only rarely seen benefit of luminance and then only in special cases. the...
Richard, The benefit is when you can process differents things with Photoshop. Exemple : If I take the OIII, this channel is often with much more noise than...
i can manipulate any channel separately I want to, Nicholas. I am not trying to argue but I don't understand your point. Are you taking oxygen for example and...
Richard, How do you can manipulate channels separatly and keep the manipulation on memory ? If I try to work only on channels, how you can keep and change the...
my method is simple but effective I just manipulate each channel stack independently as a separate b/w image, I process it to look as good as I can make it,...
Ok Richard, I understand now. For me, I create immediatly the color version with my FITS image with merge fonction on CS and work my curves and levels to...
yes, i'd like to take a shot at processing your data. if you can provide the stacked fit data without any further processing that would be nice to compare the...
I'm getting into narrowband imaging and am looking for advice on how best to get started. I've done some imaging, and liked the results of H-alpha so much...

looks nice Nicholas too bad it isn't centered better. I guess that's what happens when self-guiding with SBIG rather than using a separate guide camera/scope? ...
It's a trade off, Richard. I think most everything is a tradeoff. Personally I hate having to get the guide star on the tracking chip. I'm also really...
