NGC3628 and it’s “tidal tail”

It very rarely happens that we ‘ve got 9 nights in a row (around new Moon!) here in Belgium. Next to the main setup I have put the little SharpStar to use to capture- every night 10-minute frames of this area. Even with the Optolong LPS the large field gave a clear gradiënt of light pollution.

Seeing the tail appear after 145 frames made me smile 🙂
So yes it’s possible to capture this feature in SQM 20 type skies, you only need a lot of patience I guess (or a faster scope).

For now a final NGC3628, in color!

I had finally a break in the clouds, no moon, to capture some color for my NGC3628. This color was already long waited for ( I started the first luminance February 24th). So I added 7x300s Blue, Red and Green. I combined those in Photoshop with the previous Luminance. See all details on Astrobin

An intermediate NGC3628

This galaxy is the third member of the Leo triplet. During the last nights I could image this with the Esprit120mm and the ASI183MM Pro. This intermediate result is L-filter 6hr36m of data processed in APP and cropped. Best seen by clicking on the image!

And below is the equivalent image taken with the Nikon D750 DSLR. I had a lot of noise in this 3hrs picture (36x300s), I suspect something went wrong with the dithering. The tidal stream is just visible.
