Little session - Moon, M42, a few carbon stars and doubles

[Stu 31,314]

I had a few hours free last night, which remarkably coincided with clear skies, so I had a nice little session from around 8 until 10.30 ish.

The moon was an obvious target, and I spent a decent amount of time panning along the terminator enjoying the views. I was rather obsessed with trying to spot craterlets on Plato, although I'm not sure whether last night was the best phase or not. I managed a grand total of two with a suspected third, not amazing! The seeing varied from fairly decent to fairly wobbly depending upon whether it was over the neighbours garden or house!

Next up M42 obviously. Even without a filter the nebulosity showed well, clear tints of green to my eye. Switching from 24mm Pan to Nag Zoom showed the Trap at between x123 and x246. Whilst the E star was fairly clear at times, F was nothing more than a 'might be' every now and then. I know the scope is capable of it, the seeing just isn't a lot of the time.

I tried the binoviewers out too, to see whether they made any improvement on the Trap and Moon. The Trap was a no, I think E was slightly harder with the binos, and the Moon was an unfair comparison because it had gone over the neighbours house. Will repeat the exercise under better conditions.

I then made a start at a few Carbon stars, having added a number of lists to SkySafari. I find these lists very handy  as the basis for an observing session and highly recommend having a look at them if you haven't already. Sorted by transit time I picked off a few without too much slewing.

Hind's Crimson star kind of stole the show, such a lovely deep red colour. In comparison the others I viewed on the list seemed far more orange but I'll persevere and see how I get on.

WZ Cassiopeiae appeared on both the Carbon stars and the coloured doubles list, a quite wide pair at 57.7", one orange and the other white. Similar brightness at mag 7.1 and 8.3

BL Orionis and V613 Monocerotis were the other two I got, fairly unremarkable I found but still rewarding identifying them in the star fields.

Sigma Cass and Iota Cass were the last two doubles that I picked. Sigma was, I think, a new one for me. Nice tight (3.1") uneven double, mags 4.88 and 7.24. To my eye they looked similar in colour, white.

Iota is a lovely one as we all know. Not something I view very often, must try harder, but at x123 with the Nag Zoom the three components were beautifully resolved. I'm sure I could have used lower mag but didn't bother changing eye pieces. Higher mag increased the split obviously, but somehow I preferred the tight star shapes and split at the 6mm setting.

So, nice little session with the Tak/AZGTi setup which is my usual these days. Lightweight so easy to setup and alignment quick and easy.

Grubby little iPhone shot attached, plus some detail of the SS lists I have loaded.

A good report of a productive session. I've been making more use of the lists facility in sky safari also. I've got a list I put together called "LP List" which is a set of targets that are good in light polluted conditions - its a montage mostly of the easier messier objects, caldwell objects, and brighter double stars but they add up to a lot of targets and so a lot of choice even in bad conditions.

There is a list of 111 targets for light polluted skies, have you seen it?

Nice report Stu. Nice session! Tried to have a few hours tonight, but managed approx 20 to 30mins max with clouds closing in earlier. Not checked out the LP list in Skysafari, but I’ll check them out.

Doh! I have now!

Nice double star list from the Cambridge double star atlas there too!

Super report Stu.  Carbon stars the future !

Cheers Nick, I'll definitely work my way through them. Not sure any will rival Hinds for redness though, stunning!

Good report Stu - makes me want to get out there.

I’ve only observed Hind’s crimson star once but it really amazed me how blood red it looked, unlike any star I had seen before. Lovely!

Lovely report Stu, you got through a lot of objects in 2.5 hours!

Thanks for sharing☺

These are the best I could find from the list. All with a colour index of between 4 & 5. Nothing close the Hind's though which is 5.70. No wonder it looked so much redder!

Thanks Dave. Felt like I could have got through more of the Carbon stars but that's how it goes. Will pick them up again next time. Was messing with the Binoviewers for a little while, and also kicked the tripod so had to to realign it!

Just downloaded a load of these lists - thanks for the heads up guys.

Slightly disappointed Stu -  I can't see any Plato Craterlets

You are clearly not squinting in the right way Andrew  

[Littleguy80 4,944]

Fab report, Stu. I was pleased to read that you picked up the green tint in M42. I see this regularly too but not everyone seems to be so lucky!

If you get a chance, perhaps you could upload some of the observing lists in this thread. There’s some good ones in there already

Having done some further research into this crushing failure Andrew, it seems the problem is I don't have a TEC160!

Now where can I find me one of them?

Yes, it's great when you see it. I find it quite dependent on the conditions, probably due to older, less sensitive eyes.

I'll have another look at that thread. I think some are there already but will add any that are missing.

Thanks Stu. Don't worry if not. I just thought you'd probably have some good ones being such an avid user of SkySafari

Great report Stu, Hinds crimson is a show stopper Try Mu Cephei that is another great view.

[Stu 31,314]

Thanks Paul, will have a look. The Garnet star isn't it?
