Ngc 289

[furgle (Adam)]

The weather's been atrocious lately. I'm now caught up on all my data processing.


Here's spiral galaxy NGC289. It's probably too dim of a target to attempt from the suburbs, but I did manage to get some of the outer arm details.

That's an attractive galaxy Adam.
Quite a challenge I'm sure given its small size and low brightness.
Congrats.

That looks to be a tough target Adam. The resolution is pretty good with structure seen in the inner arms. Maybe the background is a little blue though.

I'd be very pleased with that, Adam. A beautiful galaxy. Looks like there is some interaction with the little fellow at 1 o'clock. I wondered if the saturation is the tiniest bit high, but Trish thinks it's just right.

Best,
Mike

+1 That's a terrific shot.
