M101 the Pinwheel Galaxy. About 21 million light years from earth in the constellation Ursa Major. Approx 252,00 lights years across. The 6 defraction spikes on the stars are a result of having 3 spider vanes to hold the secondary mirror instead of the usual 4. Typical Takahashi weirdness.
ZWO ASI2600mc camera with the Takahashi Mewlon 180 Dall-Kirkham telescope.
From the backyard 10 miles east of Austin TX.

@Astrobum Wow a gorgeous shot! Amazing you did it so close to Austin. What was your total integration time?
@hendric
Thanks! Total time was 140 minutes. 70 120 sec subs. I use an Antlia quadband filter to cut light pollution. There's a large rise in elevation between me and Austin so that helps.
