Denis BuczynskiParticipant
Hello all, I was able to observe on around 100 nights in 2018, this does not include the months of June Aand July where bright all night twilight stops me observing.So around a third of the nights have been used for observation this is simliar to other years I have been at Tarbatness. I reported 1540 astrometric postions of comets to MPC. An average of 3 positions for each comet gives around 500 comets (many are the the same comet observed on different nights). My two automatic meteors cameras (12mm and 3.8mm fl) recorded at total of 4891 meteors. Strangely there was only 1 digit differnce between the two cameras over the year (2445 , 2446).
Observational astronomy is a nice pass-time isn’t it?

Denis BuczynskiParticipantI seem to remember that visual double star measurments were the main use for this telescope, am I correct/ it is a dual reflecting telecope with 12 and 10 inch mirrors mounted in parallel fashion.
Denis BuczynskiParticipantHi Helen, here is a preliminary ephemeris by Nakano published on CBET 4569
Nakano provides the following preliminary ephemeris for the comet:

Talk of large eyepieces made me think of the thread on Antique Telescope Forum about the Great Melbourne Telescope and the low power eyepiece used on it. Here is a picture of the eyepiece with a field lens of 8 inch diameter! That is a large eyepiece.
Denis BuczynskiParticipantHi Erik,
Why do you need to adjust the uprights for levelling. Just use bolt down supports like these from Wicks (4″x4″) and cut them the correct length and use a long spirit level to get them true before fixing them. I have used these on a good few observatories that I have built over the years without problems.
Best of luck.

Denis BuczynskiParticipantHi Gary,
Great image of this comet in outburst. Lovely colour image with plenty of the tail detail recorded. I have saved this image for inclusion in the BAA Comet Archive. It would be appreciated if you would send any further comet images you take to thie BAA Comet Section at

Denis BuczynskiParticipantHi Jack,
I do not see a picture of McClean in my copy of Analysis of Starlight, only descriptions of his work.Jeremy’s request was for a reference to a picture of him.Attached is a picture of him from the PDF I referred to in my earlier post.
Best wishes
Denis
Denis BuczynskiParticipantHi Jeremy, There is a thumbnail image of Frank McClean in this PDF

Denis BuczynskiDenis BuczynskiParticipantSad sad news. Maurice was a pioneer for amateurs a great observer and always a pleasure to work with. Nick James and my self were able to confirm his SN discovery in 2011 , he was pleased about that. His London home observatory was always active and ever changing as he incorporated new technology as it became available. he will be sorely missed by all in the BAA who knew him. Rip Maurice.
Denis Buczynski
Denis BuczynskiParticipantI have been able to get observations on a good few nights since outburst occurred. I can get to the area of sky where it is located but it is in bright twilight for me here at Tarbatness. The 15th mag companion star just to the north of the nova is now showing on my images. Just to blow my own trumpet I got a reference in that Darnley/ Starrfield paper as being one of the first to report photometry. I seem to have good luck with getting onto nova quickly after outburst is announced.
Denis BuczynskiParticipantHi Adam,
I don’t know if I can help but I have a series of my own drawings of Saturn made during the edgeways ring plane passege of 1980. The moons are identified on 7 of my drawings. If these are of any use I can scan them and email them to you. Let me know.
Denis
Denis BuczynskiParticipantHi Eric,
I never watched the programme, although I knew about it. I will catch it at some point on utube. One disapointing aspect of the aftermath of Roy passing was that no one seems to have rescued any of his own build telescopes, including the 10 inch with which he made his comet discovery, nor any of his astronomical papers etc. Surely some one in his home town of Northampton would have known about his death at the time.
Denis BuczynskiParticipantThanks for posting this published obituary of John, it was an interesting read about a very interesting man.Sad that he is no longer with us.
Denis
Denis BuczynskiParticipantHi Gary ,
Interesting to see this new version of the VSS Circular. It seems to be the way that things are going these days. The BAA digital subscription will be good news for those groaning book shelves.
Denis
Denis BuczynskiParticipantThanks Peter and Andy.
I should and could have looked at Who’s Who myself. Just laziness on my part, sorry. It would be useful if the email addresses of the Trustees were appended to their thumbnail imags on Who’s Who.
Thanks Denis
Denis BuczynskiParticipantHello all and Happy New Year,
Looking at my observing data I see that I observed comets on 101 nights in 2017. That excludes the period between mid May to mid August when the twilight sky is too bright here in Highland Scotland. I submitted more than 1200 astrometric positions of comets to the MPC (3 per comet in a single night) and the BAA Comet Section. My 2 automatic meteor cameras recorded about 3000 meteors( some duplicates) they are turned off during the May – August all night twilight. This summary does not include any observations of Aurora nor NLC.Nor any nights I was away from home and unable to observe. not exactly New Mexico but not bad for the cloudy UK. Persistance and retirement from work are the key to observing regularly.

Denis BuczynskiParticipantHi Tony again,
I have now looked at my third copy of this atlas, which is named Atlas of The Heavens and not Atlas Coeli. It is published by Sky Publishing in 1969. All the charts in it are in negative form. This I think is field edition and not rare. The earler copies of the Atlas I have are, one that is entitled Atlas of The Heavens and was published in 1949 by Sky Publishing containing maps on individual sheets sized 24×18 inches. The other I have is one entitled Atlas Coeli published by Czech Academy( in 4 languages Czech, Russian, English and German) in 1962 it contains bound maps in sheets 21×15 inches. All are for Epoch 1950.0. Looking at your picture of the Atlas you have it looks a modern edition with a folding bound maps. This is probably the desk edition.This and the negative maps were probably able to be purchased together. So I think you have a modern set of maps and no hens teeth are present! Still a great set of star maps though. If you need any pics of the various copies I have let me know.
Denis
Denis BuczynskiParticipantHi Tony,
I looked at my early editon of this atlas and a later one and neither have negative maps included with them. Are the negative maps produced by Sky Publishing in the same way as the positive maps? Perhaps they have been copied from the positive maps by previous owner.When you say you want to research them, what are you wanting to find out?
Denis
ps Skelnate Pleso Observatory and its history is absorbing. The details of the people and and observers there is fascinating. Becvar was just one (maybe the most important) but Mrkos, Padjusakova, Kresak , Vovarova and the other comet discoverers and astronomers there were huge characters also.
6 November 2017 at 6:47 pm in reply to: UK Location of best number of clear nights and seeing #578726Denis BuczynskiParticipantThere doesn’t seem to be a lot wrong with the Tarbatness Peninsula in NE Scotland where I moved to 7 years ago. Plenty of observing opportunities and good views of Aurora too. Long way from anywhere else though, and a maybe a big cold for those southern folk who are used to warmer climes. But for observing I cannot complain.
Denis Buczynski
Denis BuczynskiParticipantHi Tony,
Two of my friends have built run off rooof observatories and they are happy with the outcomes. Here are some details of the rollers and rails they used.
http://www.rollingcenter.co.uk/
The rail for these wheels are the “Angula Z3”. They come in 3 metre length
The wheels were £4.44 each – I got 6
the rails cost £22.64 for a 3metre lengtH
The ‘V’ groove wheels & rails are superb – it really is possible to push it with one finger.Denis Buczynski
