Description

Giving my APM130 and CEM70 a break and instead have my Askar400 out to play on my CEM40 instead.

Still getting up to speed with my new ASI2600mm which gives a nice widefield on the Askar 400...enough to cover the entire Lagoon-Trifid region here.

Taken over three nights. Most is Ha, OIII and SII but also a few hours on LRGB for hopefully improved star colour and to capture some of that reflection nebula near the trifid. Narrowband subs 160 x 300s. LRGB 80 x 180s.

I stacked into channels in APP and then processed SHO and LRGB separately in Startools 1.8alpha. I did some layer blending in Startools and also in PS with further tweaking to taste.
