Hi Michael, The Syntha's corrected field seems to be good at this size. Image looks good, another advantage of narrow band: provided you have sharp enough...
Hi Neil, Thanks very much for tip!!! I have never used this technique, my PS knowlegde is just average, but I will investigate it. Is it a filter or specific...

Thanks, Peter. I must admit that I decided to try the "propeller" in narrowband (see below) after inspecting one of your 400/2.8 widefield Ha shots of the...

just catching up here John, What a nice image! the widefield "survey" shots are great for finding new target opportunities. a funky knot may be very awesome at...
Thanks for the vote of confidence, but almost all of Cepheus (except IC1396, which I was trying last night) is behind trees for me. I also made an attempt at...

got it!!! great nice new tool, thanks very much for this very valuable hint, hmmm... like it! a ... From: Neil Fleming To: narrowbandimaging@yahoogroups.com ...
yes Neil, it is basicaly the imbalance between OIII and SII vs H alpha. H alpha is usually clean and smooth, SII is dim but not as noisy as OIII. I am going to...
Hi Peter, Sorry to hear about the trees. You can borrow my chain saw if it helps. I like the propeller at the longer focal length. Regards, John ... From:...
I appreciate the offer. You would be greatly amused by the chain saw saga that accidentally led to my even being able to see IC1396. I doubt that "Saturday...
I have mixed results here (I am using the 6nm AD). If I image O[III] in the zenith with with low relative humidity I have no gradients. My O[III] gradient...
I can tell you that I consistently see better results in terms of [OIII] gradients when i use a 3nm CS filter instead of the wider bandwidth astrodon. it is a...
They don't have a 3nm listed on their site...just the 4.5. I'm thinking that maybe the 4.5 might be better anyhow, with the fast F/5 FSQ light cone. ... ...
give it a try and then measure the contrast with each the gradients aren't necessarily a killer but they certainly are extra work I'd prefer to minimize there...
Good afternoon, While paging through Rob Gendler's new book, I ran across this interesting nebula in Cepheus, NGC 7822, and decided to image it with the Nikon...
Gorgeous Peter! Clear skies, Kevin Dixon www.kevindixon.westhost.com From: erdmanpe This last moon window also came with good weather, so this is my second...
Nice image, Kevin! I believe this is one of Richard's favorites in Hubble. He has captured it using a couple of different scopes. Regards, John ... From:...
Another beauty, Peter. There is an intriguing dark nebula river that winds south of NA and the Pelican. Does it have a designation? I'm still working on...
Thanks John. I should have known that the master of the Hubble palette, Richard, would have imaged this beauty. Now I have an excellent image to benchmark...
