Just 1 min of total exposure time

文章 LT » 週四 09 12月, 2021 08:58

Really can't imagine it is possible to get a similar result at the film era taking great Orion nebula just in 1 minute. Digital sensors are really much much sensitive than films.

A test shot to check for the star quality after a quick optical alignment at home before the trip for shooting comet Leonard.

Taken with DIY 6" F4 Newtonian + Vixen corrector PH + 100Da in Sai Kung at the dawn of Dec 6th @570mm F3.8
2x30s @iso1600, unguided
Stacked in DSS with 1 dark and 1 flat calibrated
Processed in PI
Final touch in PS
