Hi Richard actually when i view them side by side...i prefer the first version...go figure..lol great job on imaging this large object... jamie ... down ... ...
HI i took Richard's suggestion and reprocessed the original hh555 image i posted...the ha channel was a bit clipped....i unclipped it and lowered the high end...
HI this object in IC5070 i've heard as referred to the elephants trunk..but if you look closely at my image..you can see that really there's a full elephant...
Hi Matt, That's a nice first attempt! If there's anything I see, the focus *may* be a little bit off - the stars seem a bit bloated, and the dark regions in...
Hi Eric, Thanks for taking a look and for commenting! Still working on this one, hoping to finish it up soon. Thanks again! Matt ... From: eja24601 To:...
HI Matt sorry I didn't reply earlier. I meant to and then got busy processing my images and shooting new ones and just ran out of time. I would say that you...
Thanks Richard! Concerning the Hb, what do you think about using the Lumicon UHC filter that passes both OIII lines as well as the Hb? Would that be a better...
well the kai sensors really need about 40 to 45 minutes for ha subexposures. if you can guide that long you are going to be way ahead taking the longer subs ...
Hi Richard, I don't think 40-45 minute exposures are strictly necessary, although they can help. For instance here is a 8 x 20min exposure with a ST2000XM and...
That is simply hauntingly beautiful Richard. Clear skies, Kevin Dixon www.kevindixon.westhost.com ... From: Richard Crisp To: narrowbandimaging@yahoogroups.com...
And the extra effort paid off Jamie. That is a sweet image! Clear skies, Kevin Dixon www.kevindixon.westhost.com From: Jamie HI i took Richard's suggestion...
couple of comments worth noting the ST2000 was using a 10nm Schuler filter I was using a 3nm Cust Sci filter. There's a very significant differerence in...
Hi Richard - I prefer the original image. It may be pushed a bit but it brings out color that is not seen in the second iteration. Either way, it is a...
there may be a happy medium where the image is not so vivid but the reds show up better. I need to spend some more time fiddling with it. sometimes it takes me...
... Interesting... I thought the QE ratio between the two cameras was in the 2-2.5x range in HAlpha? If so, wouldn't that just about make up the difference in...
I am finding color balance to be the most demanding part of processing NBI. I have an M27 that has wonderful detail but it has funky colors. Do you have any...
... well yes and no There is at least a 2:1 difference in QE at Ha for the sensors but the problem with the wider filters is that they let more broadband pass...
it is hard sometimes. They usually wind up dominated by the hydrogen which is often several orders of magnitude more intense than the other lines. balance the...
Hi Kevin, I would agree with you. I like the first image better too. The loss of color in the second pass just doesn't jump out as much. Gary ... From:...
... Yea, but the NII band is WAY less prominent than HA. I'm sure it adds very little to the mix. ... Actually I don't think the percentage transmission has...
Hi Given my location - 12 miles drive E of NYC, narrowband imaging is the only game in town around here, of course only going pretty deep Image taken with...
those are all really wonderful images Adrian. I especially like your HH555 (pelican neck) and Crab shots but they are all very nice. Thanks for joining the...
... processing NBI. I have an M27 that has wonderful detail but it has funky colors. Do you have any secrets to arriving at the correct color balance? I try...
the correct urls for the images are these: 2004 (4 x 10 min/filter), 3nm filters http://www.narrowbandimaging.com/ic1396_s2hao3_widefield_page.htm 2005 (9 or...
Hi, Very nice photo's and comparison ! How did you stacked your images; in sum, median, sigma clip, or . ? Karel _____ Van: narrowbandimaging@yahoogroups.com ...
Hi all, I have 400 minutes' worth of H-alpha data that I tried doing an initial processing of recently. That's 20 x 20 minute shots. The target is the Bubble...
