Hey Guys! I have been inactive in the last 1,5 months, becaz of my semester exam in school, but now its over:) Finally I have some free time again, that i can...
I have a couple of recent images taken from my light-polluted backyard. In both images, there is a lot of background noise that manifests itself as a pattern...
Eric, Have you tried Russ Croman's Gradient XTerminator? I have had very good luck with it. http://www.rc-astro.com/resources/GradientXTerminator/index.html ...
Hi Don, Thanks for responding. Yes, I do use Russ' excellent Gradient Xterminator. The background unevenness I am working with is what is left over *after*...
I have a couple of questions regarding the appropriate software required for effective PEC and pointing efficiency. I have been reading about Gemini Level 4...
Eric, I've learned that same lesson. <g> So, instead of creating a difference layer that you use to subtract out the gradient, here's what you do: 1)...
Hello group, I'm planning my upgrade toward the "colored" world, so I'd like to know more about two sets of filters: - Astronomik Type 2; - Astrodon...
Thanks a bunch, Neil! This is something to try for. Hopefully as early as tonight, if I'm in the mood. I started from scratch last night, and I have a...
Jim and Ron - thank you very much for your comments. That was the answer I was hoping for and appreciate your confirmation that I can indeed get away with a...
I recently purchased a Clement focuser for use on my C11 and have a Robofocus unit on the way. My CCD camera came with CCDSoft which contains the @Focus...
My system is a G11 with Gemini, about 2 months old. Great PE. I used Pempro to check my PE but it was so good that I didn't have to program it. I guess I got...
Hello Ron, These ratios look too short to me. That means with a 2000mmC8 as your imaging scope, you can use a 200mm scope? That sounds odd. Also, doesn't it...
... Steve: I suggest that you try @Focus2 in CCDSoft .... you need to create a directory under CCDSoft called AtFocus2 and then you should see the @Focus2...
I do my best to balance and flatten the background gradients during processing in CCDStack. I then do the technique below on the LRGB after importing to...
I can highly recommend focusmax, which is freeware. It does not require absolute settings as the first-light wizard runs a series of calibration routines, one...
Not sure what you mean by "look to short." The numbers may be surprising to you, but they are accurate. These are numbers tested in the field. The most...
Another thought after the gradients are removed (via Russ' program or other techniques) when there is still some background noise... Use the "color range" tool...
Hi Ron, You don't really need either one of these packages. You may want one or both, but that's a different question <G> MI-250's are known for low,...
Hi Szigeti, M61 came out really nice! The background is a little uneven around the galaxy, I can't really tell what caused it -- maybe something in the flat...
Ron, What I meant was that to guide a C8 at f/10 for example, a 200mm FL guidescope seems too short. I was under the impression that you want to guide with a...
Hi Paul and Tom - thanks for taking the time to share your experience. Agree that the "want" and "need" case is always on the table! I understand that each...
Hi Stefano, I only have experience with the Astrodon filters with my ST-2000. I am very pleased with the performance, it seems darn near 1:1:1 to me, at least...
It would be perfectly reasonable to guide a 2000mm scope with a 200mm guide scope using CCD for both. I know it probably comes as a shock considering the rules...
Hi all- I was wondering why so many imagers seem to prefer the 11000 to the 6303 chip. Is this purly for the extra field or desire for NABG at the apparnent...
I can speak for myself on that. My number one reason for wanting the 11000 over the 6303 is the lack of blooming. I have dark skies, and if I want exposures...
I think they were for manual guiding. Steve ... From: "Wodaski - Yahoo" <yahoo@...> To: <ccd-newastro@yahoogroups.com> Sent: Thursday, June 01, 2006...
