... Yes. And keep auto-stretch turned off so it won't bite you unexpectedly. The type of stretch you are doing has no negative impacts, however. But it's ...
Thanks Ron for the explanation. That's what looked like what was happening, but I wasn't sure. rb ... From: Wodaski Yahoo To: ccd-newastro@yahoogroups.com ...
I'm trying out the new CCDAutopilot and attempting to quantify the number of steps that fit in the critical focus zone. I did a focus run where I got the...
Ron & Richard, I have no doubt about the results of the test. I would caution about making judgements about the entire line based on a sample of one, at one...
Randy, I altered the histogram in CCDSoft to help do a gradient adjustment just before color combine, saved and opened immediately in PS CS. I noticed that the...
Mark et.al., The monitor issue probably is down in the noise compared to the printer. Most printers people are using are dye based pigment. These begin to fade...
Hi Ron, I've been following the thread about monitors and printers. I have owned an Epson 2200 since they first came out. I have nothing but praise for this...
I just learned from the Comets –ML group that the comet magnitudes as given in planetarium programs are subject to large errors. As I understand it, the...
Hi, The link below is my first attempt at CCD color. The frames were collected from my balcony which contends with street lights and Los Angeles Basin sky...
This is a first light image from a new camera. Ha was in order since the moon was almost full. I thought I was shooting NGC7822 but my image doesn't match what...
Hi All, Here's an image of the gibbous moon taken with a Schuler H-alpha filter. Taken with a Televue Genesis SDF af f5 and a ST10XME camera. A single .1...
Rick, If you physically "alter" the histogram, then save...yes you have changed the data. I don't know how CCDSoft handles "screen stretching" to just adjust...
Rick, That's a really impressive "first"! I think you handled the light pollution and gradients extremely well. As I said before...knowing how much of a...
I'm not sure exactly how bad his conditions are, but if he's in the LA basin, that shot is excellent for ANYBODY, let alone as a first color image! VERY well...
Hi Mark.That is some observatory. You do things in a big way :) And your images are equally as nice. I have booked marked your site. From what I see I imagine...
Hi Dan, It looks like this might be part of 7822, but a detached portion of it. I would have thought it would have it's own designation, but I can't find one....
Thanks Marc and Randy, As several have noted, the histogram looks weird, because I manipulated selections in PS to try and remove gradient effects. I am still...
Hi Group, I am using a C14 with St2000 and Focal Reducer at F8. I would like to try the new STL11000 camera to get a much bigger field of view. But is this a...
As I mentioned in my previous email, I have just purchased a ST8i ABG camera and am waiting for some adapters to arrive so that I can start imaging with it. ...
Serge, I use 25 exposures. I also often bin my color channels, so I need binned darks. Also, I find that my darks taken in a temperature comparable to the...
