NGC 2392 in Ha

Well here in Minnesota a day of spring arrived yesterday. The high was 36 deg ABOVE zero! No jackets, hats or gloves! Anyway, even though the moon was out and there was persistant very thin clouds, I had to get the scope out. The equipment works much better when it is "warm" out. I chose NGC 2392 and imaged the planetary in Ha light to minimize the moonglow. Didn't turn out too bad considering.
