Hi, I'm a complete newbie to astrophotography. Took my first photos over Thanksgiving but haven't seen the results yet. My question is: Where / How do you...
Greg, Back when I was doing film I ran into the same problems. I made up a very short T-ring to 1.25" tube for may camera and then would just slide the camera...
Hi Greg, Adding to Phil's comments, if you are shooting b&w, you can use an LPR filter, but if you are shooting color, it will whack the colors pretty good. If...
Greg: I'll second the 2" adapter that jeff is talking about. I have the Televue version and use it all the time. It'll work with your film & digital cameras,...
Dear Friends: Our next PAS General Meeting will be held on Friday, Dec. 9 at 7:30PM in our usual meeting place in Rm. 5001, Bldg. 5000. Our speaker will be...
In my ongoing efforts to wring out this Atik 2HS web cam for all it is worth, I think I have pretty much hit the ceiling. Interestingly, background or dark...
Hi Jim, Even though you feel you've hit a limit, I think it is amazing what you have been able to do with that web cam. Great job! -Ray ... Interestingly, ... ...
Those pictures (especially the crescent) show lots of detail. Fwiw, last year when I was doing some work with the st7e + 6nm Ha, even with the cooled kodak...
Thanks, Ray, It continues to be a fun, and, uuuuusssually, a rewarding experience. I've learned quite a bit about my GM8 mount by way of manual guiding, and...
Already on it, Jeff. As you suggest, Guidedog is a pretty effective program for utilizing the webcam as an auto guider. Haven't yet started but will be...
I would like to play around with astrophotography from my house. From everything I have read that means narrowband imaging. For starters I plan to get a 13nm...
Regarding economically effective astro imaging devices... Fwiw, a while ago I bought a used ST7E for a "decent" price. These are now going for even less, and,...
Hi Rob, I would say that generally speaking a faster scope with the same focal length would be preferable for narrowband imaging. It should improve your...
... Dunno. I got excited because the initial AM posting said, "$10k off". When I looked at their website and saw $13k, I mistakenly thought the price would...
Hi Phil However, this brings up a good point. The problem with cheap refractors is chromatic abberations, mostly. If the collimation is on and there are no...
Hi Ray, I think it is a SBIG year end sale. I know OPT and BT Technologies have the ST-8 and STL-6303 for the same price. If I recall correctly, SBIG has a...
That was my thinking also. The 120 has more then 2x the surface area and a faster f ratio. The TV-76 also has advantages since I installed a fine focuser. I...
Hi Rob, I too have the 120ST and was recently wondering the exact same thing regarding narrow band H-alpha and possibly OIII filters with the achromat. My...
... I suspect the ST120 is not going to be a flat field. (Pete S. uses one; maybe he can comment on its performance w/ the Rebel 350XT.) The chinese focusers...
Thanks for all of the replies. I think I will try the imaging with the TV-76 and consign the ST120 to Houge park. It will probably require longer exposures,...
I tried an experiment with shooting M42 as a B&W image. This gave a result that I do not understand. When I looked at the image using the Canon tools it looked...
... When I shoot w/ the DSLR I save the images in RAW format. Afaict, at least w/ the 300D, there is no "B&W setting" for RAW. For the halpha images, I...
Rob, You probably had the 20D "Quality" set for RAW plus a JPEG, and the "Parameters" set to B&W. The camera always images in full color, then makes another...
Jeff, The ST7 looks pretty good, and certainly a major step up from a web cam. I am presently looking seriously at an entry level camera offered by Finger ...
