Clouds clouds clouds

But there was a brief break tonight, so I hot-footed it over to the observatory. Before the clouds came over again I managed so nice views of the Moon, and I spent a while checking out the smaller craters in Mare Crisium. Then, battling with the clouds, I managed the Ring Nebula at 11pm, not yet fully dark, so good, and I split the ‘double double’ with the 9mm eyepiece. Albereo, then a cup of coffee as the clouds rolled over and Capella was really low twinkling away.
Jupiter rose about 11.30, but the big dob won’t go low enough to get it. I wish my 8″ was back in there to be honest. It’s infuriating seeing stuff in the sky you want to look at, and not being able to get the scope on it.
I did get a glimpse of a very cloudy Jupiter in the 4″ on returning to my van. One moon, and a disc with no markings. Then I drove home.
Not exactly ten galaxies tonight, was it?

A galaxy far, far away…

Yea, I’ve gotten into the habit of listening to Star Wars soundtracks every time I drive to the observatory.
tel2It’s twenty to three but sod it, I’ll write up my observation notes while they’re fresh in my head. I started in Bootes, and early on I got a little frustrated because it was too light and I couldn’t navigate the new Telrad finder. But after midnight the darker skies kicked in and M3 and M53 (in Bootes and Coma Berenices) were found. Two globulars with M3 being the showcase. I looked for an NGC cluster by M3 but no luck (too bright?). I also tried to star hop the faint stars of Coma Berenices – there’s loads on M numbers there. I did find one galaxy, though I know not which one yet*. I made a sketch and I’m hoping to match the star field around it in Stellarium.
Leo won’t be around much longer, so I tried for the Leo galaxy ‘triplet’. The Telrad really helped, and I found M65 and M66. Moving along in Leo, I found M95 and M96 but not M105, which should have been in the same field of view. In my Messier Book (it says M105 is a ‘fuzzy blob’. Perhaps I misidentified it as a star?


View through the Telrad

M51 in Ursa Major (Canes Venatici really) was quite a treat, with structure visible, (a hint of ‘spiralling’). Easily found again.
Staying with the Plough, I next found M108, and it’s been years since I’ve seen this. It was certainly shaping up to be a galactical evening! M109 next, and again, it’s been years, and the nucleus of the galaxy seems to have a star-like point of light in it. Just along from M109 is the planetary nebula M97, the ‘Owl’. Quite apt, as I was hearing owls all night. I didn’t see any structure, just a surprisingly bright nebulous fuzz.
What else? M13, great. I saw M92 too, only a few nights ago. And another globular, and another ‘first time in ages’ sighting of M54, half way between Alberio and the outer stars of the Lyra ‘box’. Cool. It’s a pretty sight in a rich star field, being close to Cygnus.
And of course, I took in the Ring Nebula.
Back to The plough, and the galaxies M81 and M82 were superb in the 16″. This has to be the prettiest sight galaxy-wise, as the edge-on spiral contrasts with the larger, side-on Bodes Galaxy.
I think I realised by this point I’d seen nine galaxies, and I started hunting for M40 in Ursa Major to get the ten. No luck. Only now, with my lovely Messier books on my lap do I see that M40 isn’t a galaxy as I thought, it’s a double star!
Jupiter, Saturn, both rising in the early hours and no way to get the telescope on them, because the Dob touches the wall of the dome. Grrrr.
Good session though. Nine galaxies, a few globular clusters and a couple of planetary nebula, (I’m reading there’s only four in the Messier catalogue. Next session I’ll try and see all four).
A good night’s astronomy. Love it!

Edit, I just remembered I saw M64, so that’s ten galaxies …. though I do need to find which was the on I saw in Coma Berenices.
* and a further edit – the mystery galaxy in Coma Berenices was M85. A tenth magnitude galaxy 60 million light years away. Wow.

Looks like I’ve got to update my Messier list. Deep joy!

All Our Lives Are Lived In Circles

Things heavenly move so fast, like a turning wheel. Why is Leo over my flats as I put the van away just? It only seems last week Orion wasn’t even that far west. And why wasn’t Orion here so long this year? (of course, he was, we just didn’t see him so often).
I’ve just got back from the observatory and the 16″ scope needs adjustment, or something. Using the barlow on my SLR and T mount I could get some shots, but the focus was rubbish. Neither of the large-mirror society telescopes I’ve used have performed anywhere near as good as my old 10″ Dob, or even my never 8″. I really should put that dob back together for the summer, with a ‘correct view’ finderscope and a red dot finder. That’d suit me.
Anyway, I was fed up with the large scope, but did get a bit of bino action in later, and saw the Ed Asich Star Field, (Draconis) and the double star Pherkad, one of the ‘Guardians of the Pole’. Cool! I get lots of fun from the Sky at Night Magazine Binocular Sky section.
And in other news, I did a talk at a school, (in the church of the school yet!), and I’ve got three lovely books on astronomy history, about Copernicus, Galileo and the Hershells.

The Heratige 100p Table-top Dob

I’ve made a wooden box for my 4″ table-top reflector. Partly made from new floorboards, |I’ve made it so the scope doesn’t get battered in the van, and It’ll also double as a table. I took it over Shropshire recently and it performed admirably. The globular clusters of M13, M92 and M3 all appeared bright and sharp, and alongside me Opticrom 10X50s, and exH01cellent ‘wide field’ evening was had, (Beehive, Bernice’s Hair, etc). Constellation wise, Hercules and Bootes made their first appearance of 2019 (to me, anyway).
Although I took my 8″ reflector to the Elan Valley last October, when I was in the actual Dark Sky site, I found the 4″ on a photography tripod a lot easier to H03use. Not least because it was so cold, at -4, that I didn’t relish setting up an equatorial mount.
I’m going to write up my observations of Sagittarius and Capricorn from that evening sometime, it really is a rare chance I get to look towards the galactic centre.


Looking towards Perseus in the Elan Valley October 2018


Recent observations (that I can remember)

While it’s all still in my head, a quick write-up of tonight’s observatory antics.
Riiiight. M42 & 43, obviously. But also M78 through the 16″. A faint emission nebula, two stars ‘inside’. Great stuff.
All through the 16″ mirror, the great open clusters of M35, M37 and M38. Steve, who turned up with his go-to, showed me the globular cluster M3 and I was all why haven’t I been looking at this more!. Through the 16″ it was stunningly bright. Superb! Found by ‘star hopping’ from Arcturus in Bootees. Over to the right, a smaller globular, M53, but still a very worthwhile sight.
I found M3 in the dob also, by the way. So I get to say I properly found that.
M1 (supernova remnant) in Taurus found, and it was surprisingly bright in the 16″.
I looked at M40 below Sirius, (the ‘Little Beehive’) with the go-to.
Leo was almost lost in the eastern Wolverhampton haze, but I still found the two elliptical galaxies, M65 and M66. Later, as it moved into darker skies toward the west, I tried to find more but the dew beat me.
The double cluster was stunning through the 16″.
I should write up the other stuff I’ve seen lately. I did an evening amongst Taurus’s open clusters at the observatory site with my 8″ reflector in mid Feb, and it was great fun. Chalk up NGC , 1647, NGC 1746, and the fantastic ‘Poor Man’s Double Cluster’, NGC 1817 and 1817. It really does look like a malnourished version of Perseus’ showpiece.
The same evening I perambulated Canis Major, and more delightful NGC open clusters (2362, 2354), and the lovely Messier open clusters M46 and M47. Both distinctly different.
The most detailed star map I’ve found on Cassiopeia is in the ‘on-line download’ section of the Sky at Night magazine, as part of their deep-sky tour series. I’ve printed and laminated their map of the western area, and I spend a couple of hours with the 16″ enjoying the open and often sparse clusters in the imagined triangle between the double cluster and the first two stars of the ‘W’.
Here’s the tick-list.
Trumpler 1
NGC 654
NGC 663
NGC 659
All clusters, and some of them a lot more ‘wow’ than M103, which makes me wonder what was going on with the M numbers, (in the same way the double cluster has no M number but the Pleiades do!).
But you can’t argue with the M numbers. Especially if you’ve just bought a £28 book.
Phew! I still need to write up the binocular and 4″ mirror observations I made in the Elan Valley in October. Hmm.
