    Irregular dwarf galaxy IC 1613

    Visually in my 10" Cave this galaxy is very dim. I see mostly the bar running across it and the star forming region to the upper left (northeast). I've not had a chance to try it in anything larger.

    Some sources say this is a satellite of M31, other sources say it is just a member of the local group. At about 2.4 million light years it is a bit closer than M31. The intense star formation going on indicates something recently tidally disrupted it. Most likely M31 though it is about 40 degrees from it in the sky. This was imaged through the ice that is perpetually in the air over my lake this time of the year. I wanted to get it before winter weather caused this but with nothing but clouds all fall it wasn't possible. I might as well be imaging from Times Square for all the gradients that throws through the image and how high it makes my background count. I'll have to try again next fall without the ice but this will do for now.

    14" LX200R, L=7x10' binned 2x2, RGB=1x10' each color binned 3x3 (needs more), STL-11000XM, Paramount ME

    Reduced by a third to hid some of the noise from the ice I was imaging through. Scale is 1.5" of arc per pixel.

    Excellent! Nice resolution of those extra-galactic stars.

    Nice exploratory shot of an intersting subject, looks like the star formation region offers many clusters and Ha nebs. It deserves a revisit, a much longer set of exposures when the condx are better (maybe with a FR to reduce the FL for a wider FOV).

    Nice work on such a faint object. The bar and semi spiral star forming region a plainly evident. It seems we all wish for more data.

    Kind regards

    Focal reducer won't help, I'm already seeing the full FOV of the scope.

    Beautiful shot. The clarity and color in the galaxy is outstanding.

    Very Impressive Rick!, So many details can be seen in such a dim subject and some distant neighbors (Galaxies) could be seen in the background. Simply Oustanding. Clear Skies
