Hi all:

Had a great time imaging this beautiful transit last evening. At an elevation of only 19 to 20 degrees it's hard to record much detail. The right image is a composite of 1575 frames taken at 3:12UT and the left image is 300 frames taken just 6 minutes later. Meade 10" SCT at f/28 (Ultima 2X), SPC900NC, Baader UV/IR cut, Rv4, Seeing: 4/10.

Take it easy, Dan

PS: If your eyes stay crossed, don't blame me... 8O

Hi all,

Here is a couple of Jupiter's from August 10, shot about 2 hrs apart. Jupiter was about 27 degrees for the earlier image and 33 degrees for the later one.

Hi all,

Here is a Jupiter on August 21 in average conditions. Just for jollies I shot an image with my TOA-130 (5.1" APO) at F/44 for comparison.

Just reporting on tonight's experiment. Even though I speculate that the Canon Powershot A530 already has an IR blocking filter, I decided to try an additional Lumicon IR blocking filter (in case it has a slightly different spectral response.) I don't see an improvement, but I also was messing with other things too so the verdict is still out on that one. This time I used the new Parks 7.5 mm Gold Series with a Japan made 2x Celestron Ultima barlow in the Criterion RV-6 (a 6" newtonian) and it was way way overkill on magnification when combined with the 7.5, so much so that it left me with poor quality videos (even though the seeing was good) and only permitted me to stack a small amount of frames. Also, Registax didn't seem to like the larger scale objects in the videos and actually lost the tracking on some of them (it hasn't done that in awhile.) I basically have to decide whether it's worth using the barlow, because the overmagnification is causing too much darkness (but I'll also have to try it without the IR filter). I didn't adjust the exposure on purpose) and here in this dark room I can see Io to the left, but I'm guessing when you read this it will be difficult to see Jupiter in a well lit room (let alone Io), however whenever I tried to adjust the exposure, it just made Jupiter look very un-natural, so I just left it alone to show what happened and reduced the overall size to 75% of the original.

Shot from my light polluted backyard observatory, Meade 10" LX-200GPS, Philips Vesta Pro 675K webcam (OLD!) and a Celestron Ultima 2x barlow (f/20).

1200 frames, stacked with Registax.

Hope you'll like it, 8)

This is a composite of two images of Neptune, one that was over exposed to capture Triton. It was shot with a Celestron 11" SCT and a Celestron Neximage web cam.

It's hard to get a good shot of Jupiter this year, from northern latitudes anyway. I had pretty steady skies the other night but it was still wavering where Jupiter was. I'm glad it starts to climb north again next year.

Shot with a Celestron Neximage through a CPC 1100.

My best shot from 2 nights ago.

same details as before 32 MAP points.

cheers

I got up at 3:30 and was out to the observatory at 4:00. The temp was 31 degrees. My wife bought me a funny rabbit skin hat on the streets of NY and by morning I was very happy she had!! The seeing was poor until about 6:00AM when things improved. I was frozen by then but the improved seeing was great. Attached is an image of Saturn FYI.
