This is my version of the Rosette nebula using the Hubble and taken with the ASI071 OSC camera. Telescope was a C925 EdgeHD with Hyperstar lens.
Exposure time: 4hr 50 min in total at unity gain
2hr 00 min (24 x 5 min) Ha
1h 15 min (55 x 5 min) OIII
1hr 35 min (19 x 5 min) SII
This setup is awesome. A few years ago such an image just could’ve been taken with a monochrome ccd.
Hi, I have taken mono LRGB images of M51 with my new ASI1600mm-PRO.
I have a mix of 30s, 60s, 120s subs. 100 darks, and 100 flats for each filter. About 4 hours total.
I Used DSS for alignment and stacking, then Pixinsight for LRGB combination.
My issue is that i'm not happy with the colours, the stars all appear white and the background is strange.
I have attached the Aligned LRGB images.
Can anyone point me in the right direction? Thanks!

Low shutter count. Have used this camera only twice. Once for andromeda and then for lunar eclipse.
Will supply with 2 or prob 3 batteries, whatever i have and charger

The Rosette Nebula, with its inner star cluster NGC2244
A pseudo-HDR image because it's the combination of several developments from the same stacking result (could not bring out the colored nebula and master the stars in a single dev).
Gear: Olympus E-PL6 with Skywatcher 130PDS and CC on Omegon EQ-300 tracking RA
Capture: 10 × 60s × 3200iso, no darks/flats
Processing: Regim 3.4, Fotoxx 12.01+
Site: 50km from Paris, usually Bortle 4-5
