Venus at 2.4%:  4/30/04 10" LX200 12.4mm eyepiece projection at 106mm from CCD for f/44, Nikon D-70 ISO 1600 4x1/250 second exposures.  Images made several hours prior to sunset.  Venus is 55.8 arc seconds in diameter.

Uranus and four of its moons:  This image was made with a 10 inch LX200 with eyepiece projection at f/44 and a ST-10XME CCD camera, clear filter, 2x2 binning with only a single 10 second exposure on 9/12/03 22:59 PDT.  Click here for more information.

1999 T1 McNaught-Hartley 3/29/01, very first CCD image, 10" LX200 ST-7 prime focus, "Track and Stack", the small pair of galaxies in the lower right corner are at magnitude 15.5.

C/2001 A2 LINEAR 7/12/01

C/2001 A2 LINEAR 7/12/01, stacked negative images are registered on the stars showing "comer trail".

C/2000 WM 1 LINEAR 12/14/01.  A single unfiltered 40 second image with the ST-7 and the 10" LX200 at f/6.3 prime focus.  Click here for a complete description.

C/2002 C1 Ikeya Zhang 2/28/02 in Pisces.

C/2001 Q4 (NEAT) 5/9/04, 300mm f/2.8 and Nikon D-70, guiding done with the LX200 and the ST-10XME on the comet.  Full frame at 4x3 degrees.

C/2001 Q4 Comet NEAT was imaged Sunday May 9, 2004 at 9:05 PM PDT.  This is a stack of three 30 second exposures with a Nikon D-70 DSLR and Nikon 300mm lens at f/2.8 riding piggyback on the 10 inch LX-200 that was self-guiding on the comet with the SBIG ST-10XME.  The field was cropped down from its original size to 1.88 x 1.25 degrees.  Stars are measured down to about magnitude 14 in this short 90 second exposure.

C/2001 Q4 (NEAT) 5/9/04, 300mm with 2x teleconverter and Nikon D-70, guiding done with the LX200 and the ST-10XME on the comet.

Comet C/2004 Q2 Machholz:  Imaged on 1/5/05 when it was closest to Earth at a distance of only 0.35 astronomical units (Au's).  This is a single three minute exposure with the Nikon 300mm at f/2.8 with the Nikon D-70, ISO 400.  The camera and lens were riding piggyback on the 10" LX200, guiding was done on the comet with the SBIG ST-10XME through the LX200.  No dark frame subtraction or flat field calibrations were done, North is up and East is to the left in this cropped image.  Notice the fine detail in the small tail to the East and the broad glow in a longer tail, more than 100 degrees different, toward the South.  Comet Machholz is my 14th observed comet.

Comet Machholz:  1/12/05 Nikon 300mm at f/2.8 with the ST-10XME and the blue filter, stack of 60x60 second images registered on the comet, 1x1 binning, -15C.

6/13/05 Comet 9P/ Tempel 1:

 

This is a single 30 second cropped image taken through a 150 mm aperture 600 mm focal length lens @ f/4 with the ST-10XME unfiltered, 1x1 binning.  The field is about 1/2 degree wide, North is up and East is to the left.

5/02/2006 73P/Schwassmann-Wachmann:

This is a single 30 second exposure taken with a Nikon 600mm f/4 and modified Nikon D-70 DSLR (no IR filter) on May 2, 2006 at 10:50 PM with Mel Helm.
