Description

This image is the sum of 471240 seconds, which means 130 hours and 50 minutes, taken during the months of June and a few nights of may. Instruments used: Ioptron Smart Eq mount, Canon 70-200 F4 lens (used at 100 FL), camera ASI 533, Optolong l-extreme filter. Subs(more than 5000) were 60 or 120 secs, all unguided. Aquisition done with Astroart.

My idea was to stack all frames in one shot. The only software that has been able to do so were AstroPixel Processor. Version A IS the screen shot of APP last stackinig.

Very small processing with PSS - just RGB combination, some levels and curves.

The target of this project was to image the famous Squid nebula. After 130 hours, only just an idea of that is visible.

I have put the link to download the zip file with original stacking, so that everybody can try to process. Ah, one more thing. No darks flat were used.

Thanks for looking.
