Another night of imaging with the Meade 102mm SC on the Meade LXD55 equatorial mount in the Serenity Observatory.\u00a0 Started with realigning by hand the OTA on the dovetail, as it had slipped.\u00a0 Need to take it off and tighten that single point of attachment sometime, but not last night and not just before a session.\"\"<\/p>\n

Powered up the mount, told it to do a two star alignment, using Arcturus and Mizar.\u00a0 Used the new two holer Hartmann mask to focus on Mizar and low and behold, resolved the double star and it was quite sharp.\u00a0 The Hartmann mask came off\u00a0 and told it to go to Jupiter, and it did get\u00a0 close, within the 1\/2 degree of the innermost Telrad circle.\u00a0 Found it.\u00a0 Added the dew shield and started imaging runs, two 30sec first then 180second runs.\u00a0 The seeing appeared average but the transparency poor.\u00a0 I was not happy with the ongoing image, so after 3 runs, fiddled with the focus.\u00a0 It got worse \ud83d\ude41<\/p>\n

While processing the images I noticed the Great Red Spot… on the wrong hemisphere.\u00a0 I then remembered that for some reason the equatorially mounted scope, after the 2 star align, went to Jupiter and was upside down from its normal orientation.\u00a0 Wonder why that happened?\u00a0 So in Irfanview, I rotated the image 180 degrees and all was good again.<\/p>\n

But on the other hand, updated images of the scope and observatory are annotating well.\u00a0 Still no successful imaging of Mars yet…<\/p>\n

Below is an animated compilation of all 6 or 7 imaging runs:<\/p>\n

Todo: resecure the OTA to the Dovetail, lower the tripod slightly as its new height is touching the closed roof.<\/p>\n","protected":false},"excerpt":{"rendered":"
