Description

First light with my 8" F4 ONTC Newtonian with the Televue Paracorr FF which increases FL to 920mm. Nice to have a fast scope at a darker site than the previous location (it's SQM 21.1 here).

Data was acquired between Feb 27, 2020 and Apr 21, 2020.

Calibrated and stacked with AstroPixelProcessor, processed in PixInsight.
