Description

First light with the TOA 130. The data is a combination between TOA130 and 92mm Stowaway. I wanted to try out different approach by obtaining RGB data with ASI2600MC through the Stowaway and luminance and Ha with ASI2600MM and TOA130.

I've been struggling with oblong stars with the MyT mount for several months now. I could never figure out what was causing the tracking to be off even with an excellent polar alignment report given by TSX. I gave up trying to go unguided and learned Protrack was actually causing overcorrection to the mount. By applying PEC only, PHD2 gave a of .5 asp guiding error which was much better than before where I couldn't get much lower than 1.5 - 2" asp error.
