Description

This was a test taking hundreds of short exposures and combining.

I took 300 x 0.5s L exposures and used the best 190.

I took 300 x 1.5s R/G/B exposures.

Taken with an 8 inch f/4 Newtonian at a sampling of 0.98 arcsec/pixel.

I drizzled the L data so the sampling was 0.49 arcsec/pixel and then ran deconvolution on this image.

I aligned the RGB data to the deconvoluted L image and produced an LRGB final product.
