This is a stack of 10 frames, taken with a Toucam Pro and an 8" Newtonian from Los Angeles.

BIG Saturn.

Posted By Jake Jacobson

Hi All -

Just got done with the full stack. This is 127 images, shot with a Toucam Pro. Alignment with Registax, and processing with PSE. Telescope was an 8" Newtonian (Konus).

Jupiter on Dec 27th..

Posted By Jake Jacobson

Here are three Jupiter shots, from Dec. 27th. Seeing was poor, so there were not many usable frames. Each image is a stack of between 5 and 9 frames each.

Taken with a 8" Konus newtonian and a Toucam Pro from Los Angeles, CA.

Interesting Jupiter Feature..

Posted By Jake Jacobson

I observed this interesting porthole on the 30th, and was also able to image it. I couldn't stay up late enough last night to see it again.

Pretty neat activity for the "dull" side of Jupiter!

Hope everyone has a Happy New Year!

Interesting Jovian Feature...

Posted By Jake Jacobson

I observed this very bright porthole on Jupiter on the 30th at approximately 1030UT. I promptly got out the camera and shot the attached image. Unfortunately, I don't have the exact time. I think it would be safe to say that 1030 is +/- 10 minutes of accuracy.

I haven't yet had a chance to spot this again. Has anyone else observed this recent feature? It is approximately the size of the GRS, and is very bright and easy to observe under steady conditions.

New Year's Jupiter

Posted By Jake Jacobson

After watching the nice moon transit last night, I captured this image of Jupiter.

Seeing was really going in and out, so I was suprised at the clarity of the image!

GRS observation..

Posted By Jake Jacobson

Finally had clear skies last night after 2 weeks of poor seeing/clouds. I was able to view the GRS transit at 500X clearly.

There are 3 small ovals lined up nicely following the GRS in the northern half of the SEB - these are very easy to view. Much activity in the STB immediately following the GRS - it appears to be "stretching out" from the GRS, and is darkened considerably.

I do not have the skills to make a drawing, but I did capture some images. Attached is a "quickie" image to show the basic details.

Jupiter and GRS..

Posted By Jake Jacobson

Here's one from last night.

Seeing was excellent. Visually, Jupiter held 500x with no image breakdown.

Unfortunately, when I removed the camera, I noticed that my secondary had become covered with dew. :-(

Nonetheless, the image came out fairly clear - but not nearly as good as it should have been, given the seeing conditions.

Jupiter Sequence

Posted By Jake Jacobson

Here's some more from the 10th. I got clouded out before I could finish the sequence. The last shot was through the clouds, and lost alot of detail because of it.

Celestron announces new GOTO mounts!

Posted By Jake Jacobson

Wow - this is new...

Celestron just announced a whole line of new GOTO gem mounted scopes. I found this info on the astronomics website:

ASC9, a 9.25” Schmidt-Cassegrain at $1699
ASC8, an 8” Schmidt-Cassegrain at $1299
ASC5, a 5” Schmidt-Cassegrain at $1099
ASC6, a 6” achromatic refractor at $999
ASC10R, a 10” f/4.7 Newtonian reflector at $1149
ASC8R, an 8” f/5 Newtonian reflector at $949
and ASCM, a computerized go-to German equatorial mount with an approximate 30 lb. payload capacity at $699.

Cool thing is that they sell the mount seperately - sounds like a little healthy competition for Meade's LXD55 line of scopes.
