Lunar eclipse July 27th 2018

As usual, we had great weather for weeks, but the night of the lunar eclipse, there were clouds and haze on the horizon, so we saw nothing of the totality, but got to see the moon after totality. I was trying to take longer exposures to get the redness of the rest of the Moon, but due to the haze, the overexposed parts glowed over the red parts, so I had to give it up. I did take some photos before the clouds rolled in and obscured the Moon again.
I used a Williams Optics Star71 with a ZWO ASI178MC at different setting from first to last to get the colors and the exposure almost the same for the different images. Exposure from 5-10 ms and gain from 0 to 175. Firecapture for capturing, and AS!3 for stacking.

The Sun on June 23d.

It has been a while since the last time I posted a solar image here, so I thought it was about time. Especially since there were a few nice sunspots out this day. For the images white light images, I used an ASI178MM camera, attatched to a Williams Optics FLT98 telescope through a Lacerta Herschel Wedge. The exposure was 0.5 ms. For the closeups, I used a Televue Powermate 2.5. Processed with AS!3, Gimp and Irfanview.  For the H-alpha image, I used a Lunt LS35 telescope with the same camera. Some dust probably on the blocking filter, so it needs to be cleaned... Click on the images for higher resolution.
