Saturn 2016

Taken @ 00:25am MST on 31-May-2016 (0725UT on 31-May-2016).
Although Saturn won't be at opposition until June 3rd, its distance at this point won't matter much.

Best 30 of 300 frames taken with the Celestron NexImage5 planetary imaging camera, Celestron 1100 EdgeHD telescope, no barlow, fl = 1960mm. Image scale 0.23 arc-secs/pixel. Video processed in ImagesPlus6.5 with RGB color channels split, aligned and re-combined.

North is up and east is to the left.

Mars at its closest 30-May-2016

Taken @ 11:33pm MST on 30-May-2016 (0633UT on 31-May-2016). Although Mars was at opposition on the 22nd of the month, tonight it was at its closest to the Earth for this year. 


Best 30 of 300 frames taken with the Celestron NexImage5 planetary imaging camera, Celestron 1100 EdgeHD telescope, no barlow, fl = 1960mm. Image scale 0.23 arc-secs/pixel. Video processed in ImagesPlus6.5 with RGB color channels split, aligned and re-combined.

North is up and east is to the left (of course) :O).

Mars in 2003

 
I was doing some video housecleaning this morning and came across some from the Great 2003 Mars Close Approach. So, I took one of the videos and used today's newer software to process.

Jupiter and Great Red Spot 28-May-2016

If you have a telescope, try to catch Jupiter in the next couple weeks while it's still overhead at a reasonable time in the evening.

Mars at Opposition 22-May-2016


Taken @ 12:22am MST (0722 UT) on 23-May-2016. Although Mars was at opposition at this point, the red planet will be at its closest to the Earth on the 30th, but the size difference will be negligible, at best a few tenths of an arc-second. Current diameter is 18.4 arc-seconds (angular width). This was from the best 30 of 300 frames taken with the Celestron NexImage5 planetary imaging camera, Celestron 1100 EdgeHD telescope, no barlow, fl = 1960mm. Image scale 0.23 arc-secs/pixel. Video processed in ImagesPlus6.5. North is up and east is to the left.

Transit of Mercury 09-May-2016

 
 
 
You had to be there to see it - visually, through an eyepiece. But, if you couldn't, this is the next best thing. Other sizes here: http://www.pbase.com/wjshaheen/image/163182013/large

Unchoking the Light


Replacing the adapter between the telescope and Off-Axis-Guider really opened up the light cone.

First night's test using the new PreciseParts adapter. See the full story and photos here.

See video showing how the part was designed on-line here.
