Cygnus region in H-alpha light, taken with 78mm f/6 Stellarvue refractor + SBIG ST-1001 ccd camera. image is a composite of 20 images, each exposed for 4 minutes.

M 57 taken with an SBIG ST-8, unfiltered. 14-inch Meade LX200GPS. 15 minute exposure.
 

27 comets in a single night. All taken with the SBIG ST-1001 ccd camera attached to the 14-inch Meade LX200GPS. Various exposures. This was featured as photo of the month on Herbert Raab's Astrometrica Sight (Europe).
 

2003 UB313, the so-called 10th planet beyound Pluto. Imaged again with the SBIG ST-1001 ccd camera and the 14-inch. Total exposure time 5 minutes. Magnitude of object was at 19.1 at time of exposure. Image was compared with Palomar Sky Survey to verify object was in correct predicted position. This is the 4th Kuiper Belt Object that I have detected with this same setup.
 

V838 Monocerotis (Light Echo). This is the light echo revealed from the explosion of the Nova V838 Monocerotis that ocurred in Jan., 2002.  This image was taken two years later and shows the expanding reflected light off of a previous shell that was expelled thousands of years ago.  Taken with the SBIG ST-1001 ccd camera and the 14-inch. This exposure was 75 minutes total exposure time and is the deepest exposure I have taken. On the original exposure, stars fainter than on the Palomar Sky Survey can be see.
 

Straight Wall area on the Moon. This is a single shot exposure 0.01 seconds long through a Wratten Green filter on the ST-8 attached to the 14-inch. I wanted to see if this camera could image the moon and it passed my expectations as to the shere amount of detail that could be seen. Numerous tiny craterlets and faults are found on some of the larger crater floors. Notice also the detail in the Straight Wall itself.
 

NGC 4298 & 4302. This is a 300 second exposure (5 minutes) with the SBIG ST-1001 and the 14 inch. Here is an edge on spiral and a face on spiral in the same field. Several years ago, this pair was made famous when Pluto appeared directly between them and was photographed with the 200 inach at the time.

Planetary Nebula Montage. Here are thumbnails of 20 planetary nebulae that I have imaged with the SBIG ST-1001 camera and the 14 -nch. Various exposure times from just a few seconds up to 5 minutes.
 

M 13. I included this commonly photographed object to show how the SBIG ST-1001 was capable of resolving faint stars in a well crowded area. If you look at the 7 o'clock position of the globular cluster, you can see the propeller effect. This is a 2 minte exposure.
 

Semeis 247, This is a large supernova remnent in Taurus near the Gemini - Auriga border. Excessively faint, this required a total of 20 minutes in H-alpha light taken through the Stellarvue 78mm f/6 refractor and the SBIG ST-1001 ccd camera. I also binned the pixels to 48 microns.  Although the nebula was visible on a single 4 minute exposure, the combined effect gave a better appearance. This is a negative view as it is much easier to see the very faint filaments and the overall glow from the nebula.
