Description

I tried to get a better SNR by putting together a Ha image of NGC7538 obtained in 2022 with the TS SD 72/432 and the color one I just processed yesterday and which sums two nights with the Seestar.
However, to obtain 30 seconds exposures with the TS72 and the AZ-GTi, I had to bin 2x2, hence the resolution is substantially the same of the Seestar.
Had I known it all beforehand, I would have taken 15s Ha shots binned 1x1.
Anyway, I used the Ha image for luminance and the color one for RGB.
The Seestar pic was imaged with the built-in DUO band (OIII and Ha) filter, so it does not really provide a complete RGB information, but that was the best I had available, given than imaging the nebula without filters from the city is essentially impossible.
