Hi Don, Thanks very much for the advise, Even with my limited experience that was the first thing I noticed about the scope. I went back and forth with...
This is an interesting development. Don't know anything about the optics except for what is posted, but I do view this as possibly the beginning of an...
Yes, this interesting, indeed. I think my main concern would be the large central obstruction at this size. I have little experience with these, however. ... ...
Hello, When i try to autoguide from ST9XE..i could not get both imager and autoguider to the same focus..only one remains in good focus and other looses it...
Hi Umair, Are you talking of a camera with dual chip ? If yes then something is wrong with the camera eg. somehow one chip has a different focusing plane...
As previously stated, this will vary with field curvature. I have noticed it on several of my cameras, especially when using focal reducers. rb ... From:...
Jim, I called Astronomics, and the scopes aren't ready yet. They are still finallizing the carbon fiber tube. There are no specs out there re: back focus,...
Dream Scopes uses the same Wynne corrector that ASA uses for their astrographs. They work very well, but they have pretty bad reflections if your filters are...
I would think it would be far less of an issue for deep sky imaging than for lunar/planetary imaging, but I suppose excessive diffraction could rob the system...
Hi all, I've just downloaded Ron's de-bloomer for MaximDl and to be honest I'm struggling a bit. If, for instance, I have 6 Lum images, do I have debloom each...
Hi Umair, What is the distance from the 0.63 reducer to the main chip? If this spacing is too far, it could produce the effect you are experiencing. ... Clear...
The 6" shouldn't cover the 11000. It is designed for the budgetary imagers in mind with smaller cameras and such. The focuser is a typical crayford on the 6"...
I read in a number of articles about how to use HA within the Red component of RGB processing. If one wanted to combine HA with LUM, would one stack the 2 in...
I've seen those and was not able to get any technical specs when I called. I'm putting my money on an 10" R/C from DeepSky Instruments (RC10C) for not much...
Hi Barry: I haven't processed any astroimages in a while, so if I'm wrong, someone please correct me, BUT my recollection is: 1. Always debloom the individual...
... To some extent, it is normal, but the question is 'how much'.... Basically, unless the scope's image is _completely_ flat, there will always be a slight...
... Not answering exactly what you're asking, but this article by Rob Gendler might be helpful: <http://www.robgendlerastropics.com/HARGB.html> Mike -- Mike...
Hi Stu, Yes. Even though the camera I use now doesn't need it I want to make sure the FOV is flat when I can upgrade to a larger sensor. Mike Siniscalchi ...
Welcome Gerald! welcome to the group. According to your interests and your equipment, I recommand you to subcribe to other groups to find more help if need. ...

Say, Mike. Do you has specs on weight and overall size for the 6 inch? Restricted as I am to lightweight equipment and modest size CCD imager, the 6 inch is...
Hello All, I'm a new member to the group and am thrilled to be here. All of the members are very knowledgable about the subjects and I appreciate any feedback...
I Robert! It's difficult for me to understand your long post, because I French. But let's go. With my knowledge, I think it will be difficult for you to...
My refractor is f/6.5 80mm WO APO 565mm focal length. I could aquire another refractor from a friend, smaller 60 mm 700mm/FL f/11.7. I think my mount can...
Bob, yeah; with the system you have right now, manual guiding is your only option. There are undoubtedly some folks out there that have modifited the drives...
Thank you for your reply it shed some light on my issue. Would the focal reducer be in addition to or instead of the guidescope. Would the 20 sec exposure be...
