This is about 13h of data on the Pacman nebula collected with a Seestar S50.
I got about 9h of data using an external SV220 filter and 4h with an Altair Ultra Sii-Oiii filter. I increased the gain to 200 to help with the SNR. I then stacked each filter separately, extracted the Ha, Oiii and Sii signal and recombined them as SHO Hubble pallete.
It is the first time I am doing a true SHO image. Although, the Sii layer needs more integration time, I am fairly happy with the result.
