Digital cameras, unlike film cameras must be fine focused on the pixel level. You can get a rough focus through the viewfinder, but final focusing must be...
Marc, you have a more discerning eye then I. I am very impressed with Petur's results. I hope to learn and retain what I learn about processing images this...
You can also use a separate focusing aid such as the Stilleto Mk IV which can sometimes be found second-hand on Astromart or similar sites for reasonable...
Hi Steve, You might want to consider a dome design option. First pour a 3' x 3' pier footing below ground level with a 18 inch round concrete column coming the...
I tried one of these a few years ago, and I wasn't very happy with it for digital photography. Given that the cost of software is roughly similar, and that...
Happy New Year's Day Everyone, With the arrival of the New Year I chose to image ngc2359 "Thor's Helmet" to celebrate 2008. I have always been facinated by...
Thanks Rick, Do you have any pictures? Steve ... From: Rick Wiggins To: ccd-newastro@yahoogroups.com Sent: Tuesday, January 01, 2008 12:34 PM Subject:...
Jim, I don't remember, since it's been some time. I've asked the question on the CCDStack help site, but not yet received a reply. It involves including one...
Ron et al, I must agree that MaxImDL is probably the premier software for imaging, but for most amateurs starting out in DSLR imaging, is a bit on the...
hello Petur, I would say by full version a one not reduce to 1200x788px. A full version in resolution is about 4000x2600 with a little croping to cut the...

Hello Folks, More commonly called the "Running Man Nebula", this galactic traveler just seems to be going somewhere -- much like everything else in the...

hello due to the enormous quantity of access petitions to my web site, yahoo suspended temporally the access. I hope it will be re-established soon. If you...
Hello Folks, A couple of images to share with you. One is of a reflection nebula, ngc1333 imaged in LRGB sequence with the TMB152 and STL6303. As you may...
Hi Mike, I think the streaking is caused by fixed pattern noise. It is described in Ron Wodaski's book. Effectively the signal to noise ratio is very low in...
Those streaks are too wide to be pixel pattern noise. Could be literal streaks on the surface of the CCD, or reflections from a nearby bright star off of the...
Hello John, Thanks for the comments on the ngc1333 image "streaking" issues. I used 10 subframes each L(10min ea) RGB((15min ea) for this image -- all of...
Sorry Ron, I was thinking of Figure 5.2.3 on page 193 of your book. Do'h Cheers Homer Simpson ... From: Yahoo - Wodaski To: ccd-newastro@yahoogroups.com Sent:...
Hi Ron and Mike, I have seen identical streaking form a bright star or even the Moon just out of the FOV. It is very position sensitive (i.e. it may go away as...
Hi Mike, Sorry. I was way of the issue with the comments. I sometimes get banding with DSLR work (which looks like that) but never with a cooled CCD. Fixed...
Hi all, i'd like to share the last result of the Bubble nebula. http://www.dsi-astronomie.de/NGC7635.htm image data: Date: 2007-12-20 Scope: Meade 10'' ARC ...
