California nebula

Posted By Roland Christen
Taken by Dennis DiCicco with AP130GTX and TCC at F4.5 with 16803 chip. Posted image is half size, Jpeg compressed.
This was a test image to see if our new 130 with dedicated telecompressor would cover the larger 16803 chip size. Indeed it does splendidly. Dennis notes that star sizes in the center measure 1.2 pixels FWHM and corners measure 1.4 FWHM.

M33 remake

Posted By Roland Christen
A few clear nights allowed George and I to shoot some more frames. Still, it's hard to get really deep when the sky is milky grey instead of pitch black.

Horsehead with flying ghosts and dingbats

Posted By Roland Christen
Image taken by Dennis DiCicco with 130GTX operating at F4.7, FLI 16803 CCD camera. Processed by myself to emphasize the H-a regions and dark dusty regions above the horse. There also appears to be a massive ocean wave about to break over the horse.

Visiting Mauna Kea

Posted By Roland Christen
Hi All,

Last week we vacationed in Hawaii and met some friends for observing at the 9000 ft level of Mauna Kea, somewhat below the 14,700 ft summit where all the large observatories are located. The Visitor Center is located at this level, and every night hundreds of people converge on the parking lot outside the Vis to look thru a bunch of telescopes that the staff sets up.

This first image shows two SCTs on equatorial mounts getting set up for the tourist onslaught that happens every night, 365 days of the year. In the background is the most massive mountain on Earth - Mauna Loa - rising above the marine layer (the peak is unfortunately hidden behind a nearby hill).

Leo duo

Posted By Roland Christen
Just a quick image of M65-M66 in Leo taken last 2 nights before the Moon got too bright and full. 10x10 minute exposures, STL11K camera, 12" F8 Astrograph, here at my light polluted Illinois observatory.

Leo rising after 9pm proves that spring is coming and songbirds are close behind.

Leo Duo in color

Posted By Roland Christen
I added a night of color imaging to the original and some better luminance. The seeing was better last night. 12" F8 Mak-Cass astrograph and SBIG STL11K camera.

M88 and neighborhood

Posted By Roland Christen
Clear skies last night, have telescope will shoot grin
18x10 minute exposures with 167mm F8 refractor. Moon was full, lots of local light pollution from nearby big box stores, but managed to capture a dozen or so faint galaxies around the area.

Realm of Galaxies

Posted By Roland Christen
Image centered on M86. Taken with AP 167mm aperture imaging refractor, 1000mm focal length. 20 x 10 minute exposures with QSI 683 WSG camera, scope mounted on AP 1600 mount.

Despite heavy local light pollution, the image shows dozens upon dozens of faint background galaxies down to mag 19.6.

Messier 98

Posted By Roland Christen
M98 surrounded by many faint galaxies.
The image was taken here at the AP observatory with my 175EDF refractor (with edge chip), over two nights. It consists of 30 x 600 sec subs, camera is my trusty QSI683WSG. Scope mounted on a 1600 GTO. Unfortunately I have no color data. Window of opportunity has closed for the next few days. I have identified some of the faint galaxies down to mag 19.

Saturn and Mars last night

Posted By Roland Christen
Finally had a clear night with reasonable seeing. Both Saturn and Mars are very low in the sky for me. Tried a 12" scope, but the seeing was too turbulent for that aperture. This image of the two planets was taken with my 160EDF refractor at F16 with a QHY-5 color video camera. The planets appeared sharp visually at 300x, but the video combined image shows a bit more detail than I was able to see.
