Hi Bernard, Thanks for looking and also the comment. -Ron ... From: Bernard Miller To: ccd-newastro@yahoogroups.com Sent: Monday, June 11, 2012 12:20 AM ...
Very nice Ron. Nice resolution all the way to the core. Bernard From: ccd-newastro@yahoogroups.com [mailto:ccd-newastro@yahoogroups.com] On Behalf Of...
Hi Friends, I haven't posted in a while and I have a large number of images backlogged to post, I thought I would start with the latest. This one I took this...
I took Mark's advice and fiddled around a bit more. I have been going and processing the Venus Transit images that I collected with the 90 mm Solarmax on a...
Hi Matt, Thanks, The scope is an f/6.3 Astro Physics 130GT with a 90 mm Solarmax II with BF30. The camera was an 8 bit Imaging Source 41BF02 firewire camera. I...
Hi Jeff, that's a fantastic image! Can you please list the scope and camera you used? Along with exposure info? All this solar stuff has piqued my interest....

I think they look nice. Getting the proms and surface detail together is a bit difficult (to avoid either a black rim or a too white rim), but with some...
Hi All, I am very knew to solar processing but have been trying to pull out everything that I could from the images that I took of the Venus transit. I put up...
Hi all, Time to post a new image done late March with my CDK 12,5. Unfortunately, the seeing was very poor with a FWHM from 2,6 to 3,7 arcsec. Unusual for my...
Hi, doing luminance only for awhile is a great idea. After you get that down, including focus, tracking, guiding, calibration, flats, etc., the color learning...
I really appreciate all the input Ron, and to everyone else too. I must tell you how reassuring I feel to receive input from this group. I cant wait to...
If I may add something here, cosmic ray hits also look like stars. These are normal and when you stack several darks to make the master they should go away....
Look at it this way: if darks were totally black, there would be no need to take them. They record the state of the pixels with no signal, which is uneven,...
Ed, I have two QSI cameras, a 540 and a recently purchased 683 and both have more than a few hundred hot pixels. A proper set of calibration files (bias, dark...
I haven't used Nebulosity, but assuming it is like other programs (??), the screen stretch doesn't do anything to the underlying image you are viewing unless...
Thanks so much Ron, Hap, Mark, & Mike for your replies. You are all so knowledgable, and I hope my beginner questions don't disrupt this group. Here are some...
As others have noted, they may not in fact be hot pixels. Cooling the camera as far as you can under night time temperatures, changing the screen stretch...
If you’re using software like CCDStack to view the dark frame, it will do an automatic screen stretch which will show noise, but the values of the actual...
It probably isn't a problem. Cool the camera down to -10C, and see if that doesn't reduce them. In any event, they are probably not really 'hot' pixels, just...
... You should be able to mouse-over individual pixels and view the ADU somewhere in the software. I know MaxIm and CCDStack have this feature. A truly hot...
Those “hot pixels” are very probably exaggerated by a screen stretch in your software. What software are you using to view your darks? The QSI 583 is...
Hi guys, Just got my new camera, and holy cow never did I think there were supposed to be so many hot pixels in a dark shot! As a reminder, I am totally a...
Hi, Here is an image of an interesting spiral galaxy NGC 5033. It is slightly inclined and has a very bright core with faint outer arms. Comments and ...
