Topic: Hello
Hello, I’ve just joined and wanted to see if I could post properly. I’m strictly a visual amateur astronomer and I am also physically disabled. I have several telescopes ranging from a 60mm refractor to a 235mm SCT.
Telescopes: One Newtonian, three Maksutov Cassegrains, seven refractors, and a large SCT.
Hello everyone,
my name is Andrea and I’m from Italy.
This is my first post on this forum since I’ve joined the BAA this spring. I hope my message finds you well.
I’m not really sure if this is the best section to make a post about this topic or if it would have been better to put it on the “History” forum. Anyways I’ll give it a go here.I’d like to know more about an antique Steinheil Muenchen refractor telescope that I’ve recently found on a local website for buying and selling astro-gear. I’m really interested in buying it, as I’m quite fascinated by its history, but I have to admit that I’m not an expert in ancient telescopes (this would be my first one) and so I hope that some of you can help me!
Under this message you’ll find attached some photos that the seller has shared.The instrument is 70mm in aperture and bears the serial (I think) number 8915. We don’t know in which year it was made. It comes with several accessories and in particular three eyepieces of different (and unknown) focal lengths. The telescope is complete with a lens cap and a removable black mounting block has been added to allow its use with some modern mount, since the original one is absent. The seller has told me that the instrument is usable, but probaly in need of some cleaning and restoration. I haven’t personally seen it yet, because it’s a two and a half hours drive from my hometown to the seller location.
The seller doesn’t know how much he should ask me for it (he has received wildy different quotes) and I don’t know how much to offer. Can you guys give me a quote?
Thank you for your time and I hope to hear from you!
Kind regards,Andrea
Topic: Globular Cluster Marathon
Many of you know that I have been imaging small planetary satellites of the gas and ice giants. My stamp collection is now almost full in that the remaining ones are below magnitude 22.0 at best. Some of you may be aware of https://britastro.org/section_information_/deep-sky-section-overview/observing-programmes/globular-clusters/the-gc-marathons-part-i-galactic-globular-clusters which I wrote a couple of years back. Unfortunately, a couple of links there were broken when the BAA site was updated but http://www.astropalma.com/Projects/GC_Marathon.html still works.
Accordingly, I have now started imaging GCs and will eventually put them in the BAA gallery and my personal web pages. I have only managed 14 out of 158 so far but hope to pick up a few more in the next week while Sgr et al. are still visible. At least twenty are too far south for a telescope in La Palma and a few more are visible only in the IR. To summarize: only 10% have so far been done.
I urge others to join in this escapade.
In reply to: Rev T.E.Espin’s Calver telescope :action needed
Hi Denis,
Thanks for this. Very interesting.
I have a personal interest insofar as I was a Geology PhD student in Newcastle 1976-1979 and my supervisor was the late Dr M. Hugh Battey. I seem to recall that he was one a select few who used the telescope for their own devices – he frequently invited me to join him in observations but, alas, I never was able to. This failure I have always regretted.
I believe the observatory was located at the Closehouse Estate to the west of Newcastle – at the time this was the University’s main sports centre and I often played football there. I believe the University sold off Closehouse some years ago. I always wondered what happened to the observatory/telescopes. A few years ago at a BAA meeting in Newcastle I was told that the observatories were no more and that the telescopes were in store (= lost). Believing this, I felt the University had committed a gross act barbarity.
Closehouse is now, I think, some sort of luxury hotel. It was suggested to me that the hotel now owned what was left of the observatory but my informant was not sure. I haven’t been able to find much information about it.
Are we talking about the same place? Or has my age-addled memory failed (again)?
I would be very keen to see these items at least preserved if not restored. I would help as much as I can, but I fear this would be not much in a practical sense.
Best Wishes,
Trevor
In reply to: Two Large Sunspots Groups
Thank you Denis and Mark for your images of AR2993 and AR2994, now archived. Another large sunspots has joined the show over the north-east limb.
Topic: VSS Meeting
Are there any plans for VSS meetings? It seems a long time since the last one (The joint BAA/AAVSO meeting in 2018?)

BAA Systems AdministratorIn reply to: The death of Rob Moseley
Denis,
So sad to hear about Rob’s passing. He was the chairman of the Coventry & Warwickshire Society when I first joined in 1985, and was very welcoming and friendly. I remember him lecturing to C&WAS about his observing from Conder Brow. He seemed to drift away from C&WAS and from astronomy in general over the years, although he would from time-to-time turn up for a meeting. I’m sure we’ll commemorate him in the Coventry society at our next meeting.

In reply to: Suggestions for CV stars in the Southern Hemisphere
I have come across a paper by Kato et al “Photometric study of new southern SU UMa-type dwarf novae
and candidates: V877 Ara, KK Tel and PU CMa”
So I am occasionally imaging PU CMa as it may be coming up for a superoutburst in January/February. The other two will be better placed in the spring.
In the meantime, I have joined G Poyner and IL Walton in following V1159 Ori.

In reply to: BAA Christmas Meeting
I would also like to add my thanks to the team who put together the streaming of the Christmas Lecture. Having missed the last few due to rail engineering works and then SARs-Cov 2, it was a pleasure to have been able to watch this event live on-line.
As a supporting member of the Natural History Museum (BM) I feel privileged to have twice had the opportunity to join a small group visiting the behind-the-scenes work area at the NHM where the meteorite collection is kept. On both occasions we were shown specimens by Dr Caroline Smith who was excellent in her explanations of these different types of visitors from outer space.
Professor Sara Russell’s mention of the analysis of meteorites through the electron scanning microscope and the x-ray by-product from firing the electrons reminded me of another visit to the NHM where the group on that occasion was able to handle one of the solar panels from Hubble which was brought back to earth by the space shuttle. These panels, which are basically as thin as crisp or peanut wrappers, have small impact holes. The scientist fire the electrons at the impact holes which reveal the structure of those holes and from the x-ray by-product the scientist are able to tell if the impact material was natural or man-made. If the impact material was man-made it was likely to be rocket fuel and through the spectral analysis they could determine if it came from an American or Russian rocket due to the different chemical compositions of the fuel used. I forget the exact ratio of man-made material to natural material but, if memory serves me correct, it was around forty five percent to fifty five percent. My understanding is that rocket fuel is less of a problem nowadays due to most satellites being placed in geostationary orbits.
The talk by Professor Heymans was excellent and interesting Sky Notes as always.
Many thanks,
David C Rayment.

harvard edu also gives reference to the BAA Journal: 1986 96, 5 P299 by Peter Johnson, so should be on the BAA archive DVD.
Apparently joined BAA in December 1940.
Topic: West Yorkshire
Hello all,
I have just joined the BAA and I am also a novice to astronomy. I bought a dobsonian skywatcher last year and have plenty to learn! Are there any observing sessions run by the BAA in the Yorkshire area at all?
Thanks

I had fully intended to be there in person – I had a ticket!- but was “inconvenienced”. So it was marvellous to join by Zoom, the quality was excellent and the event most enjoyable.
In reply to: Tatton Park meteorite
Hello there Jeremy – I don’t have an answer but I see the photo is by a certain Mike Peel.
A chap of the same name used to be a BAA and VSS member. Is this the same MP, and has he rejoined if so I would be very pleased to know that. Mike used to live in Lancashire.
Might you try and contact the photographer to see if he has anymore info.

David Sellers has just published a comprehensive biography of Charles Thomas Whitmell (1849-1919) a school inspector and amateur astronomer from Leeds.
Whitmell was elected to the BAA on 1895 November 27 and the RAS on 1898 December 9. He went on the eclipse expedition to Navalmoral, Spain, in 1900 where he met Lucy Foster. They subsequently married in 1903. Lucy shared Charles’ passion for astronomy and she joined the BAA in her own right on 1902 February 26.
The usual price is £27:00, but David has kindly offered a discounted price of £18:00 to BAA members. To get a copy please apply by email to Magavelda Press: magavelda@ntlworld.com
Further information about the book can be found at http://www.magavelda.co.uk/books/9780954101312.htm
