Hi Richard ... As it was probably me that brought you to this idea, I'll explain to you what I actually meant. If one has two close, parallel, plane,...
Hello That thread in August/September was mainly about the out-of- band blocking in the NIR. The result of the discussion on the NBI and ccd-tech list was: -...
this is a great "challenge" object for my mag 3.2 skies in my backyard. I am shooting this in pure emission line so far and have 7.5 hours of halpha, 7 hours...
I was very disappointed in Don 's flaming of filters half the price of his versions. I thought there were some technical flaws in the article: This link is...
maybe 100 hours is overly ambitious :-) http://www.narrowbandimaging.com/3c461_cassA_mk1sn2_cm10_geg_cs4_s2hao3_page.htm i evened out the exposure time: 7.5...
I think you have good results already. If I were to invest that much time in an object, (or the 100 hours you want to invest), I would pick a much more...
have you seen what it looks like in a hyper-spectral representation? http://upload.wikimedia.org/wikipedia/en/thumb/7/7a/Casa.jpg/750px-Casa.jpg even optically...
I see what you mean but how can one compete with space-based scopes? Why not get really deep images of objects that are larger and/or brighter to see if you...
that means I shoot the same old same old things that i've shot or everyone else has... ... From: Photon Collector To: narrowbandimaging@yahoogroups.com Sent:...
Yes, maybe so. But with your talent, persistence, and equipment, you can bring out never-before-seen depth and detail. Can you imagine how M1 might look with...
Hi folks, its been a while since my last posting, no good weather and other duties kept me away from imaging, gladly we are back :-) Cygnus and the Pelican are...
now I LIKE THAT A LOT Antonio! looks very different that others I have seen. Very nice how you gave it a neutral background color. it's a keeper for sure! rdc ...
Hello, from last Saturday, a part of the Heart Nebula, IC 1805 in Cassiopeia: http://users.skynet.be/dk.astro.photo/deepsky/ic1805.htm L : 12x20 minutes Halpha...
Thank you very much Richard, I am so glad you liked it. This shows once more that narrow band it is great for those of us living in heavily LP areas. cheers, ...
Hello Matt, This comparaison is very instructive and my favorite is the Hubble palette, the contrast is really incredible between different filters. ...
All, After spending most of the night imaging M33 I was too tired to sleep so I opted to finish out the morning with a few hours of B33. 4x30min Subs 253mm f/9...
Very nice image of the HorseHead region. Side comment: You might want to try a Median filter on the finished result to eliminate the remaining noise. Your...
normally I'd not shoot this in Halpha but I decided to try it anyway to see what it looked like. Well it looks about the same as any luminance shot with...
First Class image Richard ! Amazing what one can do with an H-alpha filter. Color would be a good addition if you have a chance. Nice work! Mike ... Richard...
Hey thanks Mike I was actually trying to decide if I wanted to try conventional color (it is nearly full moon) or continue with narrowband. I am inclined to...
Hi Richard, Sorry to hear about Tarzan - my condolences. Cheers Jon ... From: Richard Crisp To: narrowbandimaging@yahoogroups.com Sent: Wednesday, October 24,...
Hi All, I'm new memeber of this forum and soon to be narrowband imager. I have QHY8 single shot, cooled, 6nb astro camera. Is's very cabable to do narrowband...
You are getting fine results from yours too I see Dominick There's not a thing wrong with them in my assessment and as you said, they cost 1/4 the price of...
Richard, If the Ha shot of M31 looks just like the Lum filter shot, then keep shooting in Ha and use it as the Lum. At least you won't have any down time...
but if i do that Frank i will need to change my filter wheel and shoot flats again i don't have any rgb filters in that filter wheel ... From: Photon Collector...
I know what you mean. It may be worth the effort though. But on the other hand, keep shooting in Ha and get a really good mono image. I like B&W images. I'm a...
