Celestron 8 SCT/ AVX  mount, Starizona NightOwl 0.4X Focal Reducer Corrector,

ASI294MC Pro. Typically 120x30s or 60x60s. Update: M2 reprocessed for 

better contrast.

All images were acquired with Celestron 8 SCT on AVX mount with ZWO ASI294MC Pro using Starizona Night Owl operating at F/4 and light pollution filter.  Subs for the comet, Sh2-142 and Sh2-155 were 30s typical for the Harvard, MA area. I'll revisit the Sharpless targets with 60s exposures in the future to try to bring out more nebulosity. Exposures respectively for M27(my better half's favorite)  and M13 were 8s and 15s. Update: M13 reprocessed for better contrast.
