Thanks for all the advice and suggestions. At this stage I'm not too fussed about using more 'correct' filters; first aim is to become familiar the techniques,...
I am posting this web address for any who may be interested. I am in no way affiliated with this organization, but they are offering a pretty nice space...
Richard, This is very cool! The data on IC 1805 has a lot of "Heart". Very nice image. Isn't this clear weather nice? I too have captured Ha over the last 3...
I own a C-11 GPS and just aquired an 80 mm Nighthawk by Stellarvue which I intend to mount on the C-11 using a piece of channel about 18 inches long and the...
actually..there were a few things i didn't tell you...that's important the wrattens are not parfocal...which is a really nice feather in the others.... there...
While we are on the subject of the Debloomer -- I downloaded the free version to get an idea of how well it worked in cleaning up some small blooms using my...
Are you running the debloomer first before any other processing including dark frame, flats, alignment, etc? I have found that the debloomer works best on the...
I have started working with a Yankee Robotics Trifid 6303 CCD camera. So far, only in the city with bright moon light. I don't have a color wheel but I do have...
Richard, That's a very cool viewer. Well done! Don Waid ... From: Richard Bennion To: ccd-newastro@yahoogroups.com Sent: Tuesday, November 30, 2004 9:54 PM ...
After the good results on the California Nebula, I was out the next night to try imaging IC434 in h-alpha from San Diego. Once again the transparency was very...
Randy, Very nice Horse and Friends! Your image is very deep. I just did the same target with a 102mm achromatic and my ST-10XME. I had some major blooms...
Very nice image Randy! That 300mm Tamron lens is a good performer -- not to mention your excellent processing skills. Looking forward to more of your image...
Randy, That imaging setup is just working perfect for you! Super image. rb Richard A. Bennion http://www.ewellobservatory.com http://www.ccdware.com ... From:...
Don, Thanks! My ST-8XE is ABG. I give away some sensitivity and linearity but never need to deal with blooms. I am lucky that my Tamron lens is good enough to...
Rick, I use it after my reductions With large blooms I get some residual on the image from the blooms. Nothing is perfect. After I combine all the images if...
Richard, Thanks. But I also want to do colr. The RGB filters are not parfocal with this lens, at least not when wide open. I wonder if the steeper angle of...
I am not sure any filters would be parafocal with that lens. Your critical focus zone is just tiny. You can though, bin your color 2x2, which would let you get...
Hi Jason, looks good (but saturated in the trapezium and slight elongation of stars). The detail in the nebulosity is wonderful. What kind of software are you...

The f/# doesn't affect the bandpass for such broad filters, nor the index of refraction (ever). However, a low f/# does make the position of best focus more...
What is the 'piece of channel' you are refering to? ... which I intend to mount on the C-11 using a piece of channel about 18 inches long and the rings set. I...
... Just using the software that comes with the camera for control. It comes with AIP4WIN but I do most of the processing in PhotoShop. Didn't even use...
Ron, I still can't get it to work. I checked the Apply to folder box, and then clicked the button with the three dots. The select input folder dialog box...
Peter, It seems that interference filters should be sensitive to the f- ratio of the optical system. Interference filters are designed for plane-wave incidence...
