Moon illumination will 86% with the lows in the lower 50s.&nbsp; I hope to get an hour of deep sky imaging during with no moon light.&nbsp; My intended target is the Andromeda Galaxy.&nbsp; I\u2019m hoping to start with something relatively easy.&nbsp; I will then switch to the Moon and get some more shots<\/p>\n\n\n\n<p>I spent a good portion of the afternoon looking at how to accomplish a good alignment.&nbsp; I ran through SynScan two- and three-star alignment, I have to put Jupiter in the mix due to the tree line, west is out of the question, north is out of the question.&nbsp; That leaves east and south.&nbsp; Not much in the way of options due to tree lines in those directions either until later in the evening.&nbsp; So, the plan is to rough polar align, then do a one-star alignment on Jupiter.&nbsp; Then sync using Astrophotography Tool (APT) and All Sky Plate Solver (ASPS); I just finished confirming that was working.&nbsp; Now I just need to work on focusing.&nbsp; The plan is to use Jupiter in Live View to get a rough focus, that should be well enough to plate solve coordinates to sync the mount, then switch to the Bahtinov mask to fine tune the focus with long exposures.&nbsp; Once I\u2019ve got focus accomplished, I\u2019ll move to my intended target of Andromeda and we\u2019ll see what we see.<\/p>\n\n\n\n<p>Equipment being used tonight will be the Canon, the Optolong L-Pro, and the .85 reducer\/flattener for Andromeda.&nbsp; Setup started at 16:50, finished at 17:15.&nbsp;<\/p>\n\n\n\n<p>The night started out relatively decent, I aligned to Jupiter with no problems.&nbsp; Then I went to connect the camera, it wouldn\u2019t turn on.&nbsp; Got that fixed and then all there was in the live focus was round blob that wouldn\u2019t change when I tried to focus on it.&nbsp; Discovered I had tightened the set screw on the focus tube but not before I knocked the alignment out and not before I had taken the entire image train apart.&nbsp; I reinserted the diagonal with reticle and performed another alignment, again that much went smoothly.&nbsp; The mount tracked Jupiter perfectly.&nbsp; I did learn how to focus with the Bahtinov mask using Jupiter to provide the refraction spikes.&nbsp; Once I had gotten a good focus, I took off the mask and snapped an image, however it wouldn\u2019t blind solve.&nbsp; I know what that problem was though, I\u2019m pretty sure ASPS didn\u2019t have the data loaded for the mm of the OTA, a simple fix once I was back in the office.&nbsp; I tracked to Saturn and it was in the FOV but not quite, however, tracking was solid.&nbsp; I was going to turn the night into observation session only but I didn\u2019t have the hand set connected.&nbsp; Once I connected that, the scope went off into la la land for tracking, unlike the night before.&nbsp; Completely frustrated, I called it and came in.&nbsp; Now to add insult to injury I find some kind of white spec on my Barlow, needless to say, this one isn\u2019t going on The Sky Watchers<\/p>\n\n\n\n<p>Again though the night wasn\u2018t a compete loss, I did learn how to focus using the Bahtinov mask.&nbsp; And I know that I can get APT to sync the mount once I can get it to plate solve with the camera and the field flattener combined.&nbsp; That is my focus for the rest of the evening.<\/p>\n\n\n\n<p>Clear Skies!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tonight, again promises to be a beautiful clear night with sunset at 19:02 and moonrise at 21:20.
