Title: A Random Thread For Astronomical Stuff.
Post by: Basil on 08 May, 2018, 10:31:27 pm
Not sure if we need this thread.   We'll see how it goes.
Anyway,  all I wanted to say was; blimey, have you seen Jupiter tonight?   
Yo big boy.

I got into the ATM schtick around Y2K and built a 12". Thought about motorising it with scrounged stepping motors from old printers, but the gearing defeated me.

Once saw in a mag a twin 17" Cassegrain someone had built because he had dodgy eyes. That would be wonderful to have. Along with the crane & pickup to take it to a dark-sky site.

My Dob hasn't been used for years due to light pollution. It's just an ornament these days.

David will be building a 500mm Cassegrain at some point.
He's had the mirrors a while and bought a suitable tube. The observatory extension and cell are awaited, as is the  re-aluminising of the optics.

David has managed some good images from light-polluted Edgware but the new LED street light might defeat him.

Had a good view of it, although it was just rising out of the murk. Yup, it looked like an eclipse all right.

Fed up with the press & like ignorami using the term "Blood Moon" in hushed tones as if it were something out of the Apocalypse of John the Divine. It's just the Bloody Moon with a bit of grimy shadow on it.

Far more spectacular was the brilliant flare of light that preceded a faint trail with a red dot at the head of it that I saw when I looked north to see if Polaris was out yet. Meteor, or else biggish junk re-entering, probably.

It's a lovely night so I popped out for a while to see if I could see any meteorites.  Nope nothing after 15 minutes.  I know that the peak is Sat/Sun but I was hoping for something.
Perfect viewing conditions.  No moon, the track of the milky way visible, mars, clearly a disk to the naked eye, glowering in the south east where it has just risen over the Pencader hill.

Hmm.  Nice wine this.

Remarked yesterday to Mrs T42 that it was the anniversary of our eclipse party in 1999.  We were right in the centre of the shadow in 1999. I had a scope set up to project & another with a thick Mylar filter for direct viewing. It was cloudy, but the cloud broke up about half an hour in advance and we saw it all.

Funny: you can be as rational as you like, but a total eclipse is still kinda spooky.

Nope, it was the 11th.

We saw a few meteors last night a couple of hours after sunset.  Had another gander towards 3 am but Perseus was down the end of a brightly-lit street and looking that way was uncomfortable. Nowt visible. I'm always hoping for something on the Chelyabinsk scale, especially since the neighbours' modern monstrosity has great big plate glass windows.  I should think that Swift-Tuttle's débris has been pretty well swept up by now though.

Mrs T42 saw and heard a big one years ago in Uganda, which her parents poo-pooed until it was in the papers.

I could have seen the 11th one if it hadn’t been cloudy, would also have seen the Perseids, but it has been unremitting cloud for a few days.

In terms of anniversaries, it is nearly a year since this.

I have got me a new camera- Sony a3600 mirrorless. This beauty allows me to utilise the Sony Playmemories mobile app on my phone and iPad. As a result, I can link the device to the camera using the camera generated wi fi hub and veiw the image live. For astro stuff, this makes achieveing sharp focu so much easier.
My first couple of astr efforts are below. Both shot at around 21:15 on 17/09/2018, ISO 1600. The first at 1/1600 sec, the second at 1/320 sec.

Post by: fuzzy on 24 September, 2018, 11:15:19 am
Tried the new camera out on the newly driven mount last night going interstellar.

The back story is that I bought a drive kit for the Skywatcher EQ3/2 mount I got with my scope along with a polar alignment scope. Polar alignment (aligning the Right Ascension axis of the scope with the polar axis of Earth) is essential for trail free long exposures. To achieve this, you utilise a polar alignment scope which sits in the axis of the mount. The scope has a reticle which is lined up with Polaris depending on the year etc. Before attemting anything you have to ensure that the polar scope is accurately aligned to the axis of the mount.

Aligning a polar scope to a mount can be akin to herding cats. Idealy done at night and using Polaris as your target you set up and level the mount, with the elevation of the mount consistent with the lattitude of your location (51 and a tad degrees for me) and ensure that the mount is correctly orientated re North. You then put the centre of the reticle on your target and rotate them mount around the RA axis 90 degrees (either way) or 180 degrees depending on your favourite tame experts advice. Look through the polar scope and note the distance and direction that the target has wandered from the reticle centre. Now make adjustments to the 3 grub screws in the polar scope (1.5mm allan key required on my scope) to shift the reticle half way back towards the target. Then using the mount fine adjustment screws, recentre the reticle on the target. Rotate back to start point and repeat until the target stays in the centre at both points. Alignment has been achieved. Bearing in mind that Polaris is quite high in the sky (find the Big Dipper- the two stars that form the 'wall' of the bowl furthes trom the handle form guide stars, a line drawn through these two stars, from bottom of bowl to top, extending about twice the distance between the two stars points almost exactly at Polaris), looking through the polar scope every minute or two for the eons it seems to take is neck breaking. Add in the fact that my polar scope isn't illuminated so red torch use at the objective end was required AND the buggeration factor of very small, dairy product related grub screws at night meant that I was about ready to kill someone by the time I had finish. 3 attempts it took >:( Cat herding? pice of cake compared to that.

Once you have the polar scope aligned you are ready to go. When setting up, you have to do your polar alignment. Not as awkward as polar scope alignment but still a bit of a faff. Deploy mount, level mount and ensure it is North aligned. Grovel on knees and check position of Polaris in relation to polar scope reticle. Adjust and repeat until aligned.

Next you mount your scope to the tripod and then notice that the cloud has crept in and covered your intended target :facepalm:

Retire to the domicile and watch an episode of The West Wing and sup an hot coffee.

The cloud did eventually clear so out I went and set the camera and iPad up. My first target was M31 The Andromeda Galaxy-

(https://farm2.staticflickr.com/1929/44832181272_3fcc74a775_k.jpg) (https://flic.kr/p/2biEDyC)DSC00176 (https://flic.kr/p/2biEDyC) by Matt Langridge (https://www.flickr.com/photos/59790646@N05/), on Flickr

ISO1600 single frame 15 seconds

M31 is the nearest galaxy to ours and is about 2.5 million light years away (thiugh it is getting closer).

I next had a look at Mizar. Mizar is the centre star in the handle of The Big Dipper. The reason I went there is because it is a double star in that it has a companion star (Alcore). Some folk can split the two with the naked eye. Mine are shot enough that I need binoculars to do so. Mizar is about 88 light years away.

(https://farm2.staticflickr.com/1903/44882855141_8dfb7d03bb_k.jpg) (https://flic.kr/p/2bo9n92)DSC00182 (https://flic.kr/p/2bo9n92) by Matt Langridge (https://www.flickr.com/photos/59790646@N05/), on Flickr
ISO1600 single frame 5 second exposure.
Mizar is the brighter star, Alcore the slightly fainter.

Last nights images suggest my scope alignment isn't perfect as some trailing is evident though not too bad. As I get used to the basic operating methods I will progress on to multi frame capture and stacking.

That's one of the small number of things I dislike about living here, namely the lack of a dark sky. Indeed, we can normally see stars out one side of the house due to bl**dy "security lights." Why do my neighbours need either to turn these full time all night, or set them up so they turn on whenever you look in their general direction.

If you want a dark sky, we found that the cottage we rented overlooking the sea in the north of Skye (yes, yes) was the best I have ever seen. Indeed, the sky was so clear it was a little overpowering: I guess we can normally see a few hundred stars at most here in the Midlands. Up there, there were thousands and thousands I am sure I read somewhere that there are 6 000 stars visible to the naked eye. Is that right?

The first time I saw the Milky Way was around 1970 from the Scout Camp near Romford.... I bet you can't see it now from there!!

Yes.  I sleep with my curtains open.  When I first awoke at 6ish, they were shining in on me.  Venus looked fantastic without my glasses on.  An out of focus fiery thing.

I'm no astronomer, but I thought that yesterday at dawn the moon and Venus were the clearest that I'd ever seen them. Thanks to the dog needing a walk.

Didn't know Venus had a crescent though - but I suppose any planet will have, so thx for that.

Thanks T42. Not tried Mars yet. It is on the list but time and weather are the limiting factors at the moment.

The biggest impediment is set up. Deploying a tripod and scope for visual is a relatively quick process but, the set up for imaging can be quite lengthy. Polar alignment can be one of those things that goes like clockwork or takes forever!

Oh for a permanant pier or, best case scenario, a back garden obsy :D

5 day old moon 10th feb 2019
(https://i.imgur.com/2Gpv0JT.jpg)

The terminator is bisecting (from North to south) Mares Frigoris, Serenatis and Tranquillitatis.
Crater Theophilus is prominant about 1/3rd of the way up the terminator heading North, identifiable by the prominant mountain at its centre.
The prominant crater just North of mid point, with a bright Western rim and dark shadow within is Maskelyne. Move West from here to just within the terminator line and you reach the location where Neil Armstrong took his 'One small step for man....' (50 years ago this July 21st).
Slightly East and North of Maskelyne, a point of uplands/ mountains intrude into mare Tranquillitatis. This is the site of the Apollo 17 landing on 11th december 1972 in the Taurus-Littrow Valley.

Because of warnings from here we went out and watched the ISS pass overhead tonight. It couldn't have been a clearer night for it, a shame about the street lights but otherwise very clear.

Well very clear for my partner. I, on the otherhand, found out that it's not just my new cycling glasses that give a bit of double vision at distance. My new normal glasses do too. I hadn't realised due to only really being at home, at work, or on the train since I got them  :facepalm: Not that I can exactly go back to Specsavers at the moment.

Still I got to see two ISSs pass overhead at least.

And in reality it was just a bright dot moving fast but it was really really cool when you think about the fact there are three (currently) people up there gadding along at over seven and a half kilometres a second.

NASA are about to make an important scientific announcement about the moon.

I'm betting they've put Cheesoid in charge of infrared spectrosocopy, and will be stepping up the Artemis programme inna drill-baby-drill stylee on the basis of the results.

(Either that or volcanoes.)

When the sun sets on 21 December – the winter solstice – people looking up to the sky will see Jupiter and Saturn closer than anyone alive has ever seen them before.

In a Restaurant at the End of The Universe kind of way:

For anyone who misses the astronomical pairing, there will be another chance to see the sight in 2080.

No. It's the other way around. It's a winter constellation.  As the year progresses it makes its way west until it is no longer visible in the night sky.

Thx.  Now I'm confused as my increasing useless memory was telling me I see Orion to the SW in the summer nights.  I must be a half a year out.  Typical geologist is my excuse - I spend most of my time looking down and not up.

In town, so quite a lot of light, but Mrs B & I just saw a few from the back garden.

Not like when I was 14, though. Rural southern France, camping outside an old farmhouse taken over by PGL Adventure Holidays, flat on our backs looking up at the dark sky saying "There's one!", "Another!", & so on.
