Summer 2019…

….is almost over when it comes to ‘free time’ away from town. I’m hoping to catch some clear skies in the magical Elan Valley next week. Last October was fantastic, with three clear nights on the trot. If I get one, I’ll consider myself lucky.
I’ll be taking these with me. A pair of Helios 15×70 bins that were donated to the local society. IMG_5353
I managed some observing at the beginning of last week. Saturn and Jupiter are kind of playing see-saw in the South, south/west at the moment. Saturn was particularly clear and crisp at the beginning of last week, and markings on the disc could be seen through my 8″ reflector. Jupiter was less impressive, in fact, I had a better view of it through a smaller reflector at Perton Library the week before.
With Sagittarius quite low, and not too many stars recognisable, I used the 10×50 Opticroms to check out some of the Messier objects. There’s rich pickings in that constellation. I had 20190819_205704a lovely view of M22, and over to the right, the ‘in a line’ objects of M21, M21 and M8. Another reason I moved to the bins, is because the slow motion knobs on the scope’s mount had somehow gone missing. Found them now, but a bit annoying.
M20, the Triffid Nebula, is in the Scutum Spiral Arm of our galaxy, I read recently. I need to find out more about the geography of the Milky Way. I was able to capture the Scutum Star Cloud on film, (well, on pixel), last October. Here is one of my photos.


The Scutum Star Cloud October 1918

But I’m not sure if the Scutum Star Cloud is a name given to a dense cluster of stars, or just a generic name given to a brighter part of the Milky Way. Certainly, there’s such a thing as the ‘Scutum Arm’ of the Milky Way, where young stars are forming. And it’s thrilling to think I may have a chance to see it again next week.

In Lunar Mode

“we’re certainly in lunar mode” as a great modern antiquarian said. It was the 50th anniversary of the Moon landings last week,

(or about ten or so days ago), so much was going on. I saw Apollo 11 at the Imax in Telford, and it was glorious. I wanted to see it again, but work wouldn’t permit.


Andrew Lound Lecture at Perton Library

After a rather good lecture at a local library, I headed out with a friend to try and catch the lunar eclipse. Between very cloudy spells I saw (and photographed it) through the little four inch reflector I wrote about a few posts back. It was quite an impressive eclipse, helped, actually, by the clouds, which made the lit part of the moon look like a regular phase, but lit from below, rather than the side, and with much softer terminator.

The elusive M26

M26 isn’t even in my Cambridge Deep Sky album, and I can kind of see why. A few days after the summer solstice, it’s not much to see at all, but, I did see it tonight, even under the not very dark skies of Pattingham. At one point I think I saw the fainter stars of a great cluster, but then it was gone again, and I was left with a diamond shape that was, I’m afraid, one of the most underwhelming Messier objects to date. I’ll re-visit under darker skies.
The star of the night was M11, the ‘Wild Duck’ cluster that was resolved splendidly with the 18mm Kelner eyepiece. Easily found in the 10×8 Opticroms before dark. One of the greatest deep-sky objects.
I also found NGC6664, a faint open cluster, also in Scutum (as is (M26). M11 is over the border in Aquila.
I found a cluster in Ophiuchus that I knew must be M10 or M12, I wrote ‘a diamond in a triangle surrounds it’, which – I just checked Stellarium – makes it M12.
So bright was the sky, I had trouble navigating. The Telrad finderscope doesn’t magnify, which if fine under a dark sky, but with only the brightest stars at viewable with the naked eye, it’s a test.
Through the bins M13 and M92 were easily found. Saturn and Jupiter looked lovely, but inaccessible due to the observatory having a dobsonian in there at the moment, it won’t get quite low enough. Most annoying having the two greatest telescopic planets in the sky, and a 16″ mirror scope at your disposal, and not being able to look at the planets through it.
I was there a couple of hours but don’t seem to have done much list-ticking, but it was most enjoyable, just me and the owls and the fish splashing in the water over the hedge. There’s talk of putting a ‘go-to’ in the dome, which will be great, but I like star-hopping. Am thinking I should get my 10″ dob back in use and take that up to the site. It’d only take two trips from the van. Hmmm.

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!
