Quote:I watched the president of SBIG demonstrate a revolution in a new guiding technology last night at AIC. Using the benefit of a wide field guide scope and the generation of an artificial star in the imaging train, the system measures changes in movements between the two to send guiding corrections. By eliminating mirror issues, this seems like very promising new tech to end the pain of OAG and rotators for reflector systems. They are also working on multi star guiding! SBIG has become my new favorite Astro company. It seems this system will be released in the very near future.

Quote:What benefit does this system offer over an off axis guider? An off axis guider is an awesome way to get rid of differential flexure, reduce weight and get spot on guiding at long focal lengths. With today's more sensitive guiding cameras, the old issue of finding a bright enough guide star for on OAG is all but eliminated as well.
While I applaud SBIG's effort and I'm a big fan of their products.....it seems like a million dollar solution to a 50 cent problem. It's heavier, more expensive and has more points of potential failure.
Quote:Mike for those using a rotator on their system this is a godsend provided it works as promises. They don't have to take flats for every angle that used during the night including flips. They don't have to rotate to find a guide star if they don't need to. It makes things far less complicated. If you're shooting with a refractor, yep, no value to you. In that case AP has come up the perfect solution, but I'm not here to argue what's better if you love OAG then that's wonderful, and why would you care. For those of us who want a different solution hopefully there's options.

Quote:I'm sure SBIG hasn't done their research and has wasted years and 1000's on a problem that doesn't need to be fixed. Sorry I bothered to share it since it's pointless and OAG is the perfect answer for Sct's. I'll write the president of SBIG and let him know how foolish he's being!
Quote:Sorry everyone is attacking you, Mike.
Quote: Sorry everyone is attacking you, Mike. I think it's neat and if it gives us a new tool to work with, that'll be great.
Quote: have a newton astrograph, with the canon 5 dmk2; there is zero backfocus left.
Quote:Dave, just look at your tone in your writing. Mike obviously isn't quite as versed on all the options as you are. He thought it was neat and shared it. I agree with him, it's neat and i can't wait to see it.
Quote:Mike Rice said if this works as advertised it's a godsend.
