Description

M97 using the 2x barlow lens.

Subs were very noisy, I should have used longer exposure times but adding the barlow without upping the guiding didn't allow me to do so (I updated the guide scope later).

At the end the result doesn't really show more detail compared to my M97 using the same setup without the barlow , guess I learned something!

Color combination is R: Ha, G: (Ha + OIII)/2.0, B: OIII.
