IC 1805, the Heart Nebula

44 m

Reworked (let's say, "saved") an image of the IC1805 nebula ("Heart"), taken on 08/07/2024 in Pushchino (Marposadsky district) with a SW66ED refractor and an SV605CC camera without cooling enabled (first light) on a SW EQ3-2+onStep mount, guider Angeleyes 30F4, Datyson T7M, Svbony UV/IR Cut filter, Svbony filter driver. Exposure 44x1min, Gain 130, offset=0, T=15. Captured in SharpCap Pro, processed in Siril, StatNet++, NeatImage. Of course, without cooling and without offset there was a lot of noise, which had to be dealt with... Probably, it was worth it.

First light with the Svbony SV605CC camera using the IMX533 sensor without cooling, with a standard Svbony UV/IR Cut filter. Stacked 35x1min exposures in Siril without calibration, separated the nebula and star masks using StarNet++, and combined in Siril with hyperbolic stretching.
