Jupiter and Mars 5/20/2016

It was with high hopes that I went to the River Ridge Observatory Friday night. I knew the full Moon meant I would likely be alone but the Clear Sky Clock indicated that the seeing (a measure of air steadiness and a requirement for planetary photography) would be good.  Though mostly cloudy when I left the house at 8, I felt sure it clear up.  It never really quite did. The seeing was not as good as I hoped and the broken clouds were continuously revealing and then obscuring the planets and the Moon. I finally gave up around 11:30 when an unbroken layer of clouds hid the Moon and Mars and somewhere Saturn. However, my main goal was accomplished – my first picture of Mars of this opposition.  Mars will rapidly improve over the next few days then as rapidly recede as the Earth swings close by and then keeps going.  I was also treated to a singing contest between Eastern Whip-poor-wills and Chuck-will’s-widows and a Yellow-breasted Chat who couldn’t sleep.

Jupiter April 23, 2016

These two images were taken Saturday evening around 10PM a few minutes apart.  Two cameras, my ASI120MC color and its brother the ASI120MM monochrome. Both have the same number of pixels, 1.2M, so the monochrome should provide better resolution. Focusing done remotely from the laptop. Both images were created from the best 20% of 2000 10ms frames stacked with AutoStakkert!2 and processed further in Photoshop.  No Great Red Spot this time but plenty of other detail.

Sunspot 4/9/2016

Here is a reasonably large sunspot group shot with my 80mm Celestron Onyx ED and ASI120 MM camera. I got the monochromatic camera to complement the color ASI120 MC camera I use for planets and it did a good job here.  I got the scope and the light duty Celestron Nexstar mount with next year’s total solar eclipse in mind.  All three performed well today although I have to work on my technique.  I had to have Jack focus the scope while I ducked my head under a towel and peered at the laptop screen.  I’m planning to get some easy to pop up canopy for the eclipse sometime and that would help here too.  A better focuser might help. Not Jack, he did fine, but a dual speed replacement for the OEM focuser.
