Hi Arnie, I've had similar calibration errors with CCDSoft, and lots of times it eventually resolves itself after repeated calibrations (and sometimes not). My...
Hi All, Here is an image of the Eagle Nebula. The total exposure was 47 minutes. http://mrmac.mr.aps.anl.gov/~astronut/pages/M16_47minutes.htm It turns out...
HI after i finished the cocoon last night i decided to image the bubble in Ha rather than sleep.;)...believe me i paid the price for this today at work...but...

Hi All, Here is an image of IC1318b taken with an SXV-H9C camera, Epsilon-210 on an NJP mount. It is a sum of sixty-nine 1 minute images, unguided. ...
If autodark is on, and the guider is still homing in on the one pixel, you might want to discuss it with the camera manufacturer. There might be something...
Hi Jamie, I have been admiring your images. Good looking stuff!!! Arnie Rosner RAS Observatory, NM <http://www.rent-a-scope.com> 714-964-4056 24/7 _____ From:...
Hi Jamie, Very nice Bubble and Dumbell shots! (wrote "Cocoon" before...man, my brain is working a lot slower than my fingers before the first coffee) You've...

The fast relative motion of 2.9 arc seconds per minute makes for an interesting imaging challenge and a great movie opportunity. Images comprise 52 x 2 minutes...
I'm having a problem with RA tracking with my new Gemini G-11. I performed the polar align procedure that got me aligned within 2.5 arcseconds of the pole....
Thanks to all who helped me with my CCDSoft calibration problem. With your help, I have successfully calibrated my C8/ST2000/G11 setup. When I attempted...
Hello list, How does one scale an image to get the same background sky brightness between two separate images - is this achieved by using a logarithmic scale...
Arnold, What does the mount do when you turn autoguiding off? Does the mount track slow or fast? (ie: the star moves slowly in only one direction.) If it ...
It depends on what you are trying to accomplish. If one of the images has a bias relative to the other, then a simple subtraction of brightness values to bring...
Hi Peter, Thanks for checking out the new comet movie. At my northern Illinois location 9P was well below the horizon at impact. I wish I could have imaged it...
Hi Ron, I was hoping you'd pick up on this .. ;-) I'm trying to equalize - I guess it the appropriate term to use - the background between the two images.. ...
Do you have MaxIm DL? You can use Pixel Math to do this quite precisely - use the same method I describe in my first book for RGB combines where you normalize...

A guy could grow old waiting for the fog to clear around here! I had been working on new data for the Helix, and got as far as the H-alpha -- then the fog...

hi thanks....i've been working hard on my guiding...and this work has paid off...the new mount allows me to go alot longer than before jamie ... my ... bubble ...
hi you have some fantastic detail in the nebula...the stars are looking a bit harsh though....looking forward to see the final result.. jamie ... had ... alpha...
hi those oscillations sounds like your guiding in visual mode...you need to be in photo mode....if you are guiding through the rs232 it will only be set in...
Hi Clas, I didn't see any responses, so maybe no one noticed the question :-) A self-guided camera is easier to use, in my opinioni. At least it is at shorter...
Don, I tried this tonight. I disabled corrections in both X and Y axes, and ran the autoguider for twelve minutes. You could watch the guide star in the guide...
