Great to see ya here, Michael. I WAS going to say, "check your spacing", but you already have. I agree that this is definitely field issues. I have the same...

Found Neil's comments refreshing: "I have found that there is a need for an unbiased and openly enthusiastic forum ... I've established such a group ......
I have several general comments about the TV scopes of old design. I had the original NP 101 and NP 127. I no longer do. It looks like a tiny bit of rotation...
Thanks to all who've showed up in this new group! I found myself out of other narrowband options <g>. Anyhow, here is a shot I have been tinkering with for...
I should have added a few more comments. We realize that the NP series of scope from TV are Petzval designs. That means they are flat field optical systems....
Imagine that Michael. After all, we know that no good can come from an SBIG camera <vbg>. Clear skies, Kevin From: Michael Downing What's wrong Kevin; you...
Thanks, Doc. I try to remove the distracting color casts from the stars. That takes a bit of work, but I also endeavor to leave the nebulosity as unchanged...
You did quite well on the pink eyed stars I think. There is a technique that I read about one time to do this. I do not remember the details, but it goes...
I find that even with our narrowband filters, there are occasions when I find that blooming is a problem with my NABG camera (6303-based). I tend towards...
Hi Doc, I have been very happy with the flatfield of both my previous NP-101 and now NP-127 at prime focus with my ST-10XME. Here is an image without focal...
The image without the focal reducer is great. Nothing wrong with that scope. You have certainly cover all of the bases that I can think of. Reducers are a...
Beautifully rich NB image, Neil, with terrific stars. Is it safe to come into "this" NB group? <g>. Thanks for starting it. Don Goldman www.astrodon.com ... ...
Thanks, Doc. Yeah, Photoshop is a powerful tool, eh? I use a couple of different approaches, depending on the image: IF there is not much in the way of...

Hi Neil, I start to send you my best wishes to you and the NB group for this new year andt thank you for your welcome. I like both your 2 shown pictures. Maybe...
Merci beacoup, Didier. Welcome aboard! That's a good start...very smooth. Does Areo3 use the internal guide chip or a separate guidescope and camera/guide...
Nice image Neil! You really produced some nice colors, good contrast and dark backgrounds, and tight little stars with your image. I'd like to add my thanks...
Thanks Neil, I'll try to answer to your asks AREO3a (TOA150+STL11K) unfortunatly use the internal chip for autoguiding, this is more complicated and need...
Looks like your focuser is flexing, as is usual for the non-IS telescopes under the weight of large cameras. Perhaps you could add another set screw to the...
Thanks Kevin for starting an open minded group- the other one became "the narrow-minded imaging group" <VBG> Let me say that yes, certain cameras and filters...
