Description

Data acquired between April 17 and April 20 this year.

This is a 0.5x downsample with the angular resolution of about 1.5 arcsec/px; original 0.75 is too much for my seeing/guiding.

Central area of a galaxy was sharpened with an Astro Pixel Processor internal tool, than combined using GIMP with the rest of the image untouched (as an APP sharpening tool tends to mess the star cores a bit). Then applied a bit of a background noise removal with Topaz Denoise and some slight additional post-processing in Lightroom.

I think that a good old 130pds performs quite well with a 178 sensor in terms of resolution, but requires a lot of integration time for dimmer areas because of relatively low light-gathering ability (per square arcsec).
