The galaxy wiki link:  https://en.wikipedia.org/wiki/NGC_3344.

 

ASI183mm at 160 gain targeting -15C, 1 min exposures at binx2, R(62),G(55),B(53).  The telescope is  an 8" reflector at f/4. The mount is a CEM60 guided.

 

Stacked in DSS , and developed in Star Tools and Gimp.

 

Using binx2 decreases the necessary exposure time. Luminance data at binx1 could be added later.

Beautiful! I'd love to see the B image alone, sure that has glorious spiral structure.

We really do need some better names for these galaxies.

 

If I were that galaxy I would prefer just NGC-3344 or Leo Minor Gn - where n is an integer. But being called The Sliced Onion Galaxy does little for your self esteem.

Yes, that name stinks. laugh.gif   Great image, however!  Thanks for sharing.

The blue image was taken just after the galaxy reached 30 degrees altitude, or I am sure you would be right about the added detail.

 

Thanks for the nice comments.

 

Here is blue only:

Yeah the blue shows all the active star formation, the huge young OB associations, which trace out the spiral arms. All the little clumps are groups of dozens/hundreds of massively luminous hot blue stars.

 

I'm always interested to see spirals in B. INtertesting to compare them to the GALEX ultraviolet views which you can select in wikisky (amongst other places), which shows essentially the same thing but more so!
