Hi Herbert: I found the orginal config file and copied it into the Astrometrica folder. I then ran the first tutorial, but get the same "Reference Star Error...
I have a 12 inch Meade 200LX-GPS and am interested in what other Meade users typically might do to image a comet or asteroid as faint as 18th magnitude for the...
A focal reducer is not likely to improve the limiting magnitude of your system, they do offer a larger field of view but at the cost of enlarging the FWHM...

I use a 12" LX200 (classic). The focal reducer mainly gives you a wider field. With 1 minute unguided exposures under relatively dark rural midwest skies, I...

Hi, ... Very impressive! I know that going that deep with 25-cm is not easy and everything must fit to achieve it. BTW, was the CCD really a non-E ST9? Another...
