There is indeed something weird going on: I saw Betelgeuse go back to the top, and clicked on it only to be confronted with an old message. I thought there might be some comments on its evolution up to the end of the Orion season.
That is very impressive Nick. It is great to see those components – four fairly distinct ones. The sky was excellent this evening and I was pleasantly surprised with how – overall – C/2019 Y4 looked on individual subs, so I did a stack of 32 x 20s (2020-04-11T21:39:41 / Middle of exposure).
It has passed on! This comet is no more! It has ceased to be …and joined the choir invisible. THIS IS AN EX-COMET. (Well not quite.)
10 x 20s, not great transparency, 2020-04-08T20:50:20.164 /UT of midpoint of exposure.
I agree with Denis. I got all sorts of artifacts like this with Hyperstar imaging until I got the right filter. Also, I’ve done a 30arcmin MPCChecker job and there wasn’t anything around.
Hello,
I have a few ASI cameras and am familiar with ASIcap. I’ve been using the Studio suite for (I think it’s) two weeks now, but am not impressed with the live stacking app (issues around autocalibr with flats and darks) or the Img app (not configurable enough). I would get started with ASIcap for your 290mc: that app is just a little bit more configurable with regard to setting gain and offset etc. Once you get familiar with it, you’ll be able to capture both high frame rate planet videos and image stacks for things like small bright DSOs. I’m happy to put together a brief walkthrough if you wish.
T2 is in closest conjunction with the Double Cluster over the next few days. Managed to capture an image this evening during a break in clouds. I’ve finally got the ASI294MC spacing right for my Hyperstar. It has only taken a year’s work, on and off!
This argument is analogous to that been grammar descriptivists and prescriptivists. Oliver Kamm did, for some years, lay into the latter in his characteristically trenchant style in the Pedant column of The Times. IMHO, the community overwhelming thinks that 2020 is the first year of the new decade, and therefore it is the first year of the new decade. We are not talking about constants of the universe here. Nonetheless, I am willing to tolerate pedants who think otherwise. This isn’t Twitter 😉
It was unexpectedly clear for a period this evening. I caught the comet with a 200mm lens: 50 x 10s. 2020/01/21 21:40.
Yes, great to hear you got a good view Andrew. I imagine the high altitude of T2 is really helping evening visual observers.
Very nice, Robin. I was disappointed not to pick up the green outer coma with my OSC cam and Hyperstar last time, particularly with the comet being so nicely placed at the moment. But it is clear in your spectrum.
The National Science Foundation has announced the LSST is now named the Vera C. Rubin Observatory.
I thought that they covered the item reasonably well too. Hopefully everyone will be gazing south later this evening, peering through the firework smoke to look at Orion’s right shoulder…
It just doesn’t jump out of my skies. Whilst eta Ori is visible, it is so much less prominent than the belt stars that the arrow pattern does not emerge naturally in my mind. I think that Betelgeuse, Bellatrix and Rigel also frame the middle stars to be perceived as a belt.
Thanks David. The clouds are forecast to part this evening…. If they do, I will look for the arrow asterism. I have never thought this myself or even been told about it prior to your post.
Following on from Paul. Defo Bennett. Print 6, morning of 11 Apr 1970; print 7, morning of 10 Apr 1970. I may be wrong, but the bright star to the right of the comet in print 6 may be omicron And, with 2 And even further to the right.
