I won\u2019t get to see the Moon until around 22:30 or so once she clears the horizon and the tree line to the east of me. I\u2019ll have plenty of time to get my alignment straight.&nbsp; Batteries for the illuminator are here so that will prove to be a great assistance in the process with the reticle.&nbsp; I will insure I have the correct coordinates set in the mount.&nbsp; After last night, I don\u2019t think that will be a lesson soon forgotten, my legs are still feeling the pain of squatting for close to two hours.&nbsp; I\u2019ve also reconfigured the mount to the tripod to help with rough alignment.&nbsp; I set the single leg so it will be pointing to the north instead of south.&nbsp; I will also eyeball the alignment of the mount with the weight rod extended and made sure it\u2019s centered to the northern facing tripod leg.&nbsp; I can\u2019t get any closer than that until the mount is in place and leveled.&nbsp; I\u2019m going to takes some shots of the Moon using the Optalong L-Pro filter and see how they come out, should be interesting.&nbsp; I suspect I\u2019ll have to increase the exposure time.<\/p>\n\n\n\n<p>EP to be used are 25mm, 12.5mm reticle, and 5mm in conjunction with a 2x Barlow.&nbsp; The 12.5 is lighted with double cross hairs with a 40-degree FOV.&nbsp; Filter to be used is the Optalong L-Pro.<\/p>\n\n\n\n<p>I got outside around sundown and again enjoyed the Autumn air, the fact that there were no skeeters was wonderful.&nbsp; Jupiter came up over the trees to the east and south so I started polar alignment.&nbsp; It went a lot smoother with the reticle now having light.&nbsp; I also figured since I was only going to do a 1-star alignment I didn\u2019t need to wait to for astronomical twilight to end.&nbsp; I made sure the GPS coordinates were set and about 15 minutes later I was done.&nbsp; Tracking wasn\u2019t perfect but definitely a lot better than the previous night.&nbsp; Jupiter still drifted slightly but again, nothing like the night before.&nbsp; When Saturn showed up, I did a Go To and she was in the eye piece though not quite centered.&nbsp; This was her first light through my scope and I was stunned.<\/p>\n\n\n\n<p>I could clearly make out Saturn\u2019s rings, though they all looked like one big one.&nbsp; I switched back and forth between the three EP while occasionally looking at her up in the sky with just my eyes.&nbsp; My blood was rushing and I stared at her until the Moon came up and washed her away., that lasted a little over an hour.&nbsp; I switched to Jupiter and got to see her for another 10 minutes clearly before the Moon\u2019s light turned her into nothing more than a bright dot.&nbsp; That was around 21:50. The AP target for the night was going to be the Moon.<\/p>\n\n\n\n<p>I figured out how to get the 5mm to focus with the 2x Barlow by pulling the barrel back in the Barlow.&nbsp; Figured since the Canon needed some additional back focus in the image train the 5mm would be the same way and I was right.&nbsp; Unfortunately, I didn\u2019t think of it in time to look at Saturn using the 5mm with the Barlow, next time.<\/p>\n\n\n\n<p>The Moon showed herself just starting to peek through the trees above my house to the east around 22:00.&nbsp; I had been sitting for a couple of minutes when my oldest nephew joined me.&nbsp; H was worried that he might have been disturbing me, no, definitely not.&nbsp; We talked for a few moments then I started to show him the scope configuration.&nbsp; I attached the Canon with the L-Pro to the OTA and reestablished my tablet\u2019s connection to the mount PC.&nbsp; I tracked in on the Moon and there she was in Live View.&nbsp; It was an awesome thing to see the trees moving down while the Moon stayed centered in the camera.&nbsp; He thoroughly enjoyed the demonstration and especially enjoyed the live feed of the Moon. He was mesmerized when I zoomed in and could see crater details. &nbsp;He loves tech too.&nbsp; We chatted for a while until the Moon finally emerged from behind the trees.&nbsp; I experimented with several different ISO and exposure settings until I decided on ISO 400 exposure 1\/500.&nbsp; The only difference was the ISO setting from the previous night, it was 100.&nbsp; I took 30 light, 10 dark and 10 bias, I\u2019ll set the scope up and take some flats this weekend.&nbsp; We\u2019ll see what we will see.<\/p>\n\n\n\n<p>Clear Skies!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Autumn truly is my favorite time of the year, cool evenings with little to no skeeters.&nbsp; Tonight, is to be another clear night with a low of 52 degrees, humidity <a class=\"more-link\" href=\"https:\/\/www.gifnet.us\/?p=1525\">Continue Reading &rarr;<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"ngg_post_thumbnail":0},"categories":[151,162,163],"tags":[],"_links":{"self":[{"href":"https:\/\/www.gifnet.us\/index.php?rest_route=\/wp\/v2\/posts\/1525"}],"collection":[{"href":"https:\/\/www.gifnet.us\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.gifnet.us\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.gifnet.us\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gifnet.us\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1525"}],"version-history":[{"count":1,"href":"https:\/\/www.gifnet.us\/index.php?rest_route=\/wp\/v2\/posts\/1525\/revisions"}],"predecessor-version":[{"id":1526,"href":"https:\/\/www.gifnet.us\/index.php?rest_route=\/wp\/v2\/posts\/1525\/revisions\/1526"}],"wp:attachment":[{"href":"https:\/\/www.gifnet.us\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1525"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.gifnet.us\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1525"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.gifnet.us\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1525"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
