Description

Attempt at longer integration time here. This is an uncomplete photo where goal is ~35 hours total integration. slight rotation of camera yielded a smaller than desired view. Softer processing with higher integration seems to provide much better results on the eye! Haven't been able to get more than 2 hours of Oiii due to full moon while acquiring the Ha and Sii subs. Also a bit of star blotching, I believe because of low integration and low data of Oiii and Sii. Taken at F7.5, and realizing that this in combination with slightly sporadic guiding (mostly backlash I feel) of the AVX mount limits sub exposures to about 10 minutes. Could probably push to 15 minutes but would have to trash many more frames. AVX seems to be guiding relatively well compared to other reports however, with ASIAIR multi star guiding, typically can achieve average of 0.7 arcsec from bortle 8 sky shooting right through Denver light pollution (to the north). Higher quality mount would be awesome, but the AVX seems to be holding up decent for a budget mount!
