I have not tried it yet Michael, but perhaps you could try the technique that Bert Katzung posted for selection and feathering of bright objects within an...
Clear Day While taking exposures of Alnitak and Flame and Horsehead I noticed that Alnitak was a double star. Why in all of the images that I see of this...
I've recently done a similar image using basically the same equipment as you but with just an LPR filter, so basically full spectrum. Alnitak is so bright that...
Wow! Now that is somewhat unique and a real keeper. I would say you've done everything right. Hopefully you can do it again... and again... and again.... ... ...

Bob, Thank you I am working on the color now, And had to through out the green and blue since the blooms were to much I had 100 min of each, The Red on the...

Hi Don, I also saw the Jupiter shadow transit you referred to. And I also imaged it – take a look at http://home.att.net/~dpersyk/new.htm Actually, what you...
Mark, Probably because it is a double. The companion is almost 10th magnitude, and it's usually wiped out by 1st magnitude Alnitak in images. You've captured...
It's real! <g> Take a look at a HH image of mine I took as a test image last year: http://www.newastro.com/wodaski/images/new/Horsehead.ADD.research.jpg Ron...
Ron, Thank you, Should the image have more processing though then, since most of the images I see does not show this and Alnitak is much brighter Mark ... ...

Mark: Alnitak (Zeta Orionis) is actually a triple star system. The A and B components (both B0) are Mag 2.0 and 4.2, respectively, at a separation of 2.6...

Wonderful shots, Dennis. Color is great. I only have an STV greyscale image. After seeing yours, I'm glad that I didn't post it <g>. Don www.astrodon.com ...
Hello, I am trying to make some T-shirt flats with a St10XE on a C14 @ F1.9 and I end up having to shoot them though the red filter even with 2 layers of...
There will be at least subtle differences in the flats made with filters - it all depends on large a shadow is cast by the dust onto the filter, and whether...
Thanks for saying it again for me :) It is the vignetting (so far no dust) with the steep light cone I am having to deal with...I just noticed in your book...
Your choice, really. But my own preference is to keep the star sizes down. If you've been more successful than most at that, no reason to run with the ...
Dear Ron, I am using your trial DeBloomer Vers. 1.2.2 but with little success. For experimenting I croped the region of a blooming star out of an dark+flat...
I just picked up an Optec IFW with its stock RGB IR blocking filters and an L IR-blocking filter. Question: What is the correct relative times of exposure for...
Albert, If you use 1, 1, and 1.6 min.exposures for your RGB, remember use use weights of 1:1:1 in your color combine screen. Optec filters are a very different...
