Hi group can anyone help me to conect my new AO-7 with my st 2000xmc?????????and how i can make good calibration later?Do i need the 3.3 focal reducer(my...
Nikos, Although there may be someone here who can help, you might also try the SBIG group. http://groups.yahoo.com/group/sbig/ Forrest ... From: np252003...
Hi Guys, After one month of short night and bad weather, With the Full Moon in the sky, I decided to take again the M-27 nebula with more exposure and the...
Nikos, Mr. Egan's suggestion of contacting the SBIG group is excellent. I'd like to add, depending on the type of photography you're doing, a 6.7 FR may be...

I hit the mouse button BEFORE I was done..... <OOPS> That would be an incorrect assumption. Changing the input point wires to match convention does NOT...
I don't have much experience with LRGB (or even just RGB) imaging, but I don't think I'd use an O-III for the luminance frame. An O-III is a very selective...
That would be an incorrect assumption. Changing the input point wires to match convention does NOT reverse the remainder of the circuitry. It simply brings...
S*H, Huh? I don't understand your reasoning on that. If you reverse the input connections to match the reversed input plug all circuits supplied by that...
Bob, Doing that and then using a plug with reversed connections could cause sizzle if the circuit isn't protected further down the line. Switching the...
Hmmm, I am of the "stay away from circuit boards" persuasion. i.e. I would cut both wires in the middle, insert two pieces of shrink tubing on the wires,...
Apologies Phil. I've spent decades soldering circuit boards, even those %#$@*& seven layered ones! I never hesitate any longer. I repair my own ham radios too....

Well, there is another subtle reason to cut and reverse the wires. I like to leave tracks so that later I (or the next owner) can go find what I did. The...
Nikos, My understanding is that the 3.3 focal reducer will not come to focus with the AO-7. The 6.3 reducer will work. If you don't have one, you will need a...
Whatever you do, put a diode in so a polarity error won't cause too much smoke. Three ways: A diode in the supply so a reverse connection won't supply any...
Thanks for the input Dennis! Makes sense to me. Also thanks to Chris for his suggestions. Looks like a 10XE with a focal reducer might be the best option as I...
Hi John, Thank you for your message. I used the OIII CCD filter to take a different view of this famous nebula. The general narrowband filters are great to...
Okay, maybe this is a dumb question.... Seeing the traffic about RC's made me pull mine out and put it on my new (new for me anyway) scope. I have a C11...
The diagonal has a role in eating up backfocus but so does the EP you didn't mention. Try another EP with shorter fl and see what happens. The RC is sensitive...

Hi I "think" that his C11 has more backfocus than a 9.25. It "should" reach focus. However, as David mentioned, the EP does make a big difference. With the...
... It's worse than that: since the reducer reducers the size of the focused image, any EP with a field stop larger than 38*0.63 = 24mm will experience some...
Actually, the focal plane of the telescope does not change in diameter as a focal reducer is added, only the image scale changes, and that is why the field of...
