Polar Alignment Software Help....

Posted By Roland Roberts

I recently "discovered" PoleAlignMax to help me get a good polar alignment with my GM8. Last night, I used ACP to build a 30-point pointing of my mount, then downloaded the 30-day trial of MaxPoint to analyze the results. PoleAlignMax had reported an alignment error of less than 1 arc-minute after two rounds of adjustment. MaxPoint says different; it says 6 arc-minutes in altitude, and 11+ arc-minutes in azimuth. What MaxPoint seems to be missing is some cool way of helping me to adjust the alignment like PoleAlignMax does. If I use the GM8's Gemini to build my model (way slow compared to ACP's automation), then it will help me align similar to what PoleAlignMax does, just asking me to center a star in the view.

So...the question is, does anyone know of a tool that analyze MaxPoint compatible (or TPOINT compatible) data files and help me align the mount? Or is there some simple way of doing this with what I already have?

SCT to 2-inch barrel adapter?

Posted By Roland Roberts

I bought one from scopestuff (here http://www.scopestuff.com/ss_adt2.htm), but....

I want to use this on my AT66ED which is a problem. This adapter assumes you are screwing it into the back of an SCT so the butt end of the adapter hits the back of the SCT and stops. With the AT66ED, it just keeps going and there is no way to tighten the adapter. I need one with and internal stop.

Anyone know of such a beast? Yes, I know I can have one custom made....

TIA,
