Description

A somewhat over-baked (and noisey) Trifid nebula, but OK on cell phone held at arms length (if you have long arms) to blur out the noise. Shows the limitations of ASI224mc on larger DSO's that you want to capture in entirety, but don't have any room around the edges for black space to make it pop. Nevertheless, may try this again soon with the same small chip (1304 x 976 pixels) but with 45 minutes of integrated exposure instead of 15 minute (60 subs x 15 secs) from which this image came, to see if I can cut the noise further.
