Pluto movement over 3 days

My first series of images of Pluto taken July 9-11 2012 about 11 pm spaced ~24 hours apart as marked in the cross-hairs. July 11 image with M25 shows Pluto area of interest magnified as shown in second series of 3 images. I needed to identify Pluto's movement to make a positive ID among the many stars, which was fun to do.

8" EdgeHD telescope, 0.62x reducer, and SBIG ST-8300C camera. 5 minute images.

Haumea & Makemake (KBOs) 24h movement

After finding Pluto for the first time by imaging on consecutive days, I targeted two Kuiper belt dwarf planets (KBOs), March 17 & 18 about 5am EDT (0900 UTC).

Equipment C11 EdgeHD with 0.7x reducer on G11 mount, & ST-8300M ccd. For each image, 3x5min L & RGB 1x5min, cropped to fit.

Haumea (136108) in Bootes, 50 au from Earth (for comparison, Pluto is 32 au from Earth).

Makemake (136472) in Coma Berenices, 51 au from Earth. Locations and data verified by TheSkyX and SkySafari software.

M65 & Supernova 2013am

Finally got the opportunity to image M65 galaxy and the new supernova 2013am after dodging clouds with the wind dying down enough for a few hours to get good autoguiding. Seeing was not very good but had to try anyway.

AP setup: C11 EdgeHd SCT, 0.7x reducer, OAG, G11-Gemini2 mount, and ST-8300M with filter wheel.

Image details: 212 minutes total; L 10 min exposure x 10; HaRGB 7.5 min x 15 binned. Processed by Nebulosity and Photoshop CS2. Image cropped to fit.

The supernova is indicated by the cross-hairs.

Comet PanSTARRS long anti-tail

80mm refractor at f4.8 with ST-8300C ccd.  May 27 Earth crossed the plane of the comet's orbit, giving a unique opportunity to observe the comet's long anti-tail.

Comet C/2012 S1 ISON (November 8)

Early morning image (Nov. 8) as ISON clears trees in my front yard in Acton. Binned average of 6 images of 60sec exposure before twilight.
C8 EdgeHD with Hyperstar @ f/2.1 and ST-8300C ccd. This is an uncropped full frame image for the C8 Hyperstar setup.

Comet C/2013 R1 Lovejoy (November 8)

Morning image (Nov. 8) of Comet Lovejoy. This is a binned average of 16 images of 60sec exposure.
C8 EdgeHD SCT with Hyperstar (f/2.1) and ST-8300C ccd. Image is uncropped from the Hyperstar setup. Compare to my Comet ISON image with the same image scaling. Interesting how much brighter and larger Comet Lovejoy is now compared to ISON.

Exoplanet transit HAT-P-20b

This is a photometry measurement of a hot Jupiter transit across a star slightly smaller than the sun originally posted on the Exoplanet Transit Database (ETD) http://var2.astro.cz/ETD/index.php.  Data collected from a C11 EdgeHD SCT, ST8XME ccd, and G11 mount stationed at my front yard.  Since my first exoplanet transit (Wasp-3b) posted earlier, I successfully recorded 70+ exoplanet transits with C11 and C8 SCTs, which can be found on ETD.
