Hi everyone,

M20 Triffid Nebulea.

Early hours of 11.06.23.

15 x 300 seconds

ZWO 533MC Pro.

UV/IR filter.

200mm f/4 GSO Newtonian.

A few issues during the imaging session but
it proved to give results.

As usual, I am happy with the outcome.

Thanks for looking.

Paul.

One of my favourite targets, great capture Paul. Great to have a couple of consecutive clear nights down here & may get another around the new moon.

Cheers,
Mark

Hi Paul,
A fine M20 image you should be proud of especially with only an hour or so of data
Well done indeed !!
To control those big halos around the larger stars ( if your want ) try shorter subs ( 90 sec to 120 sec ) using Gain 100 or Gain 101 ( HCG mode ) on the 533MC , that’s where your read noise drops dramatically but still maintains excellent dynamic range at 13 stops. Just remember you have an extremely fast scope with loads of aperture. Cooling at -10C is again more than adequate to mitigate dark current noise. A great camera !!
Gain 101 on my 2600MC has been tremendous for the past year, a game changer in both South coasts Bortle 3 and Sydney’s Bortle 8
2 to 3 hours of 2min subs on M20 is more than adequate under your beautiful dark Bortle 3 skies as this object is quite bright.

Keep them coming
Cheers

Thanks everyone for your kind comments.

I trully appreciate them.

Martin, thanks for the tips.

Yes, I used unity gain on the 533MC Pro...@101.

Been a few stable nights here, a pleasant change,
and the place is starting to dry out.

Oh...and Im in Bortle 2.....for the record !!

Thanks again.

Safe journey.

Paul.
