    Default A beautiful Summer session



    Last night my apps were right for a change, and the seeing and transparency were quite good in my neck of the woods. As seemingly required lately, there was also a bright 3rd quarter moon… I still had one of my most enjoyable sessions. Sometimes your mood just fits the moment, and the session lifts you up, and it just be like that, man…

    I used my 120mm refractor, and dug up two of my less used eye pieces. I used my Celestron Luminos 19mm, which I loved on my previous small refractor, but had put away while using mainly the dob. It’s a really good eye piece, but not matched for reflectors, so I was getting huge distortions off center. On a frac, however, it’s beautiful. Really sharp, contrasty, makes stars pop against an inky background. The other EP I took out was the ES 82º 11mm. This one is really awesome for planets, very good contrast and colors. Not great for less bright objects though. It has a funny eye relief and geometry, with the collar too short, and I end up seeing my eye lashes and reflections. But for bright stars or planets, it’s really awesome. So my entire night was with magnifications of roughly 50x and 90x, and that worked really well. The more I do this, the less magnification I chase, and the better I find the views.

    I was in the middle of my townhouse complex again, and had several neighbors come up. I showed them Jupiter, Saturn, views of the moon, and for the former president of my HOA who is responsible for my being able to switch off some of the street lights, an additional treat of the Butterfly Cluster. The man earned it

    Targets:

    Jupiter. Beautiful, sharp, good views of the cloud bands at both magnifications. Ganymede and Callisto were lining up to the West, and Europa to the East, with Io hiding to the far side.
    SW of there, I pointed to Antares, and tried M4 West of it, but I was too close to the moon here.
    So I went North instead to Rho Oph, a very nice triple star with wide separation. Pretty triangle, almost right angled, with the brightest star forming the 90º angle. Funny enough, I think this may have been new for me! I’ll have to return in darker conditions to try for the surrounding nebula too.
    Next I headed back SE, to try to scoop the goodies I missed out on last summer. Carefully following star patterns on SkySafari, I alighted on M 62, globular cluster in Ophiuchus, new. Faint, but direct vision object, wispy nebulosity looking, well, like a globular. Surprisingly easy to find so close to Luna.
    Further trying to get my bearings in the finder, I stopped briefly at 36 Oph, double star in Ophiuchus. I believe this is new to me too! I was going to go past quickly, too lazy to put in the higher magnification, but to my surprise, I got definite separation at 50x. Gotta love refractors for this stuff, even cheap achros. Couldn’t believe I could see 5.1” of separation at this magnification. Neat tight pair of twin stars.
    Then continuing SE, I hit M 6, the Butterfly Cluster, open cluster in Scorpius, new. M6 and M7 were major misses last Scorpius season, and I was very excited to get them. This one did show the butterfly shape, paradoxically it may have done so quite well with the moon out, as I presume only the brighter stars, drawing this pattern, were showing. Very pretty sight.
    Just West of it I quickly also took a look at NGC 6383, open cluster in Scorpius, new. A fainter cluster overall, but with an easy to find bright star grouping right in the middle marking it.
    And continuing along the same line, I found (a bit later, after I had to wait for it to clear the tree line) the big brother, M 7, Ptolemy’s cluster, open cluster in Scorpius, new. Very spread out, brilliant, with lots of bright stars in the field. Quite a sight.
    By now Saturn had come up, so I headed there. Great views, nicely separated rings, some faint structure on the planet. In easy view were Titan, Tethys, and Rhea.
    I then looked around in the Sagittarius area, for some of the usual goodies. I revisited M 25, open cluster in Sgr, nice and bright; and M 24, the Sagittarius Star Cloud. The latter is not really at its best so close to the moon, and only some of the brighter members were visible.
    After that I moved to the other parts of the Milky Way, and looked around in the Cygnus area.
    Starting at Sadr, just NNE of it, I found NGC 6910, open cluster in Cygnus. I don’t think it’s a new observation, but I’m not sure, since the search function on the forum seems to be on the fritz. This one has a nice tell-tale C shape in the middle of it to identify it by. A nice cluster in a busy part of the sky.
    I then had the gall to try NGC 6888, the Crescent Nebula – in light pollution, with a bright moon. I chuckled at myself and moved on.
    SW of Gienah I went for NGC 6940, open cluster in Cygnus, new (I think). Very faint and relatively spread out, it took a lot of staring to barely see the nebulosity of faint density of stars among the foreground ones.
    I ended with a look at the Moon. The terminator was bisecting Gassendi, giving a very nice, very contrasty look at the edges and the central prominence. The rays around Copernicus were nice to show one of my neighbors who happened to be joining at the time, as were the ridges of Montes Riphaeus and Montes Carpatus. I let my eyes linger over the interesting rough terrain towards the South, and then packed up.

    All in all, a gorgeous session. Lots of new objects, including a good crop of new Messiers! And just a nice reminder of what a pleasant activity this is…

    That was a great night, Codrin! Congrats on the session!

    Interesting comments on your ES 82° 11mm. Mine is my prime galaxy hunting eyepiece behind the 18mm. I've dug a lot of faint fuzzy nuggets out of the deep with that eyepiece. Of course, that was with the 12" dob. I've not been a big fan of these eyepieces in my refractors, though. It's fun to see the differences in our preferences, eyes, and whatnot.

    Anyway, a great summertime tour. I have a particular fondness for this area of the sky as it was there that I started out and it is always like going home whenever I revisit these objects.

    Thanks for the great report!

    Nice session!
    Every once in a while everything comes together in a splendid observing session even though the circumstances are not 100%! I bet you were excited to observe M6 and M7! At least, I would have been!
    Thanks for your great report of this inspiring session!

    Very nice Codrin, some wonderful objects were observed and interacting with your neighbors is always a good thing.

    Regarding the ES 82 11mm, I used mine several years for galaxy hunting, and "thought" I was totally satisfied. But the recent acquisition of a Pentax XW10 and subsequent comparison at our dark site with the 17.5" showed me the subtle and sometimes not so subtle differences. The ES 82 11mm has since been sold and the XW10 has rightfully earned its slot in my case. All that said, the ES 82 11mm is still a fine eyepiece, but there are better out there - at a price of course.

    Thanks for the good words guys.
    I think I did a poor job explaining the issue I have with the ES 82 11mm. It feels like it's an entirely mechanical/ergonomics issue. It may be crazy, but my impression is that if the rubber collar (the part that you put your eye against) was a bit bigger and firmer, I would have no issue. As it is, I end up having my eye float just above the edge, and can't hold a steady position while search for focus and/or a fuzzy in the field. If I do push my eye closer, I end up with eyelashes in the way. That's why for a bright planet it's easier, I catch it quickly and it's easier to observe without needing a fixed eye to eye piece position. So it's hard to properly assess the optical performance given this. I may renew my search for a different collar/rim. BTW if anyone else replaced theirs, I would be grateful for a point in the right direction to get one.

    Hi Codrin. Sorry to come in late here as I missed several days due to health issues. You did a fine observing session with the XLT120 telescope. Thanks for your very nice report Codrin, and keep looking up.
