Again another attempt at Pluto. THe sky was definitely less than ideal with some thin layer of clouds to the south plus of course light pollution. However after about 15 minutes or so, an faint object was becoming distinct where Pluto was predicted to be based on Sky Safari. In the end my image was a total of about 25 minutes of exposure to try to maximize the signal of the object I think is Pluto. Ideally, next week I'll try alother image and see if the object moved.

I first wanted to get some images of the area around WX Cyg to try to get a number of stars to calculate a color transformation coefficient since the AAVSO star chart has a decent amount of stars around that area that covers a color range. I would have considered one of the standard fields from the AAVSO, but the most suitable would not have been visible until later on in the night.
Then I wanted to see if I could image Pluto. Unfortunatly it was a bit too late for that and it was at an altitude of 20 degrees or less and was soon going to have the view blocked by a house. After about 10 minutes of exposure, I think Pluto might have just been starting to become visible in the image. The estimated magnitide is about 14.5.
I also tried a quick shot of M31 and M110. M31 is definitely too large for a single frame and I didn't spend too much time on it.
After that I tried to image the Helix Nebula which was near the meridian, although also low in the sky. I only got about 460 seconds (7-8 minutes) and although some color and details started to form, it still wasn't enough and clouds started to come in at that point.
