The Bubble Nebula, up close and personal

The Bubble Nebula (NGC 7635, Sharpless 162, Caldwell 11)
My DSO camera is still at the dealer for a check, so playing with Zwo ASI385MC planet camera.
This is also unguided. I did 240 second exposures at f/7 (focal length 1470 mm). The Ioptron CEM25EC mount really keeps on rocking.
Polar alignment though has to be really dead on, so the Ioptron Ipolar polar alignment camera is doing its job really good.
Bortle 7/8
Meade LX200 8" f/10 ACF OTA
Ioptron CEM25EC mount (no guiding)
Optolong L-eNhance filter
Optec Lepus Standard 0,62x reducer
Zwo ASI385MC planet camera
Captured with SharpCap Pro
53 x 240 sec / Gain 120 / Offset 15 / White balance R50 B50
Stacked in DeepSkyStacker
Processed in SiriL and Photoshop
SiriL: photometric color calibration
Photoshop: levels, curves, noise reduction (Neat Image plugin), HLVG green reduction, star reduction.
