The FOV of view on my C14 is consistent from night to night. I have the mirror locked, so the focuser always is at the same location for a given temperature. ...
Sorry Arnie, the only comment I can come up with is : GREAT SHOT! Congratulations.... Bert Bert Katzung katzung1@... www.astronomy-images.com ... From:...
Hi Ron, you said: >> I take all darks at 10 minutes length.< . So you are always working with "REDUCTION" what, if I understand it right, is calculating the...
The library darks are of exceptional quality (64 frames is my goal; the most commonly used temps are already at that level). They scale extremely well and...
Hi Ron, I'm sorry to say that I think that you are completely wrong on this point :-) The pixel structure of the Sony devices includes a very thin 'P type'...

Another beauty Arnie. I love the number of galaxies that you have captured in this image. You certainly are an imaging machine <g>. Clear skies, Kevin Dixon ...
Ron - that is absolutely stunning. I love the color and detail that you have captured in the galaxy. The foreground stars add a beautiful dimension to the...
If you have 2x2 binned RGB and unbinned L images do you, 1. first calibrate the binned and unbinned images 2. then resize the binned images to the unbinned...
I had my first imaging sessions on the ART telescope this week. I imaged a total of sixteen hours over four nights. It was a great experience. First, you...
Ron, there is a real insight in that post and one that I'm very pleased to know about. The implications for me is that I can pretty much automate my dark frame...
Check the news, the space shuttle that was scheduled to land some mins ago is missing from radar Michael astroden [Non-text portions of this message have been...
Hello all I took 3 x 30 minute integrations of the Rosette Nebula last night, took 3 flat fields (median combine) 3 bias and 3 dark frames (all median...
You can't scale (at least not easily) in temp, just in time. CCDSoft, Mira, MaxIm DL - they all offer a way to do this, and with various options. The basic...
I don't worry about same night, but as a matter of convenience it usually winds up that I take the bias first, because it goes so fast, and then the darks....
Those are cosmic ray hits in your dark frame. You should try taking additional darks and using a median combine (or Ray Gralak's Sigma program) to remove the...
Dutch news broadcast confirms the disaster. Colombia was lost 68 km high. Pieces of it are allready found in Tx. The astronauts , 6 Americans and 1 Israeli ,...
So Ron, Let me see if I understand. Tonight while I am sitting here at my computer with clouds in the SKY. I could turn on my camera which is in my dome and...
