Hi Gary,
No I didn’t watch the whole programme. Pleasing to know that he did get credit for it.
Eric
Eric WatkinsParticipantPaul,
just checked an image on Wikipedia and the images match-no SN.
Cheers,
Eric
Eric WatkinsParticipantThanks Paul, mystery solved it would seem.
Eric
Eric WatkinsParticipantFollowing my earlier posts I have attached a couple of my images. The foreground star is obvious, however, linear stretching reveals a fainter star close to this foreground star that gets lost in the glare of the brighter star. I’ve not yet checked to see if this is normal in other archived images.
Images taken on 2018-04-20 @ 02:37 and 02:21 hrs Ut Unfiltered @ 60sec and 20 sec exposure respectively.
Using C14 edge F:7.7, QSI 532 CCD camera, binned 3×3
I also have V filtered images should they be required.
Regards,
Eric
Eric WatkinsParticipantP.S.
Apologies I used a Celestron 14 edge + paramount MEII + QSI532
Eric
Eric WatkinsParticipantHi Adam,
After reading your post I managed several images of M108 no filter at 60 and 30 sec and with a V filter at 60 sec at about 02.00-0230 UT on 2018-04-20
If you are referring to the bright centre (forground) star then this appears in images I’ve quickly looked at and hence do not think there is any urgency and will delay processing until later today as I’m far too tired now.

Eric WatkinsParticipantIan, further to martin’s excellent advice. Try visiting a local astronomical society on one of their open evenings. My local society holds monthly meetings when society members bring along their telescopes to view whats on offer in the sky for members of the public. If your lucky telescopes similar to what your considering may well be available to look through together with an experienced observer providing some initial instruction.

Eric WatkinsParticipantHi John,
the free software AstroImageJ;
( http://www.astro.louisville.edu/software/astroimagej/ )
does have a facility within it’s DP converter page that provides BJD time either on board or tick a box and it supplies the time from the uni of Ohio site mentioned on other earlier reply. Some useful instructions and manual provided by Denis Conti at;
However, the accuracy is to 5 dp and 6 respectively and you will have to set the DP converter to your site and target’s RA and DEC and be sure to always update the leap second tab before use.

Eric WatkinsParticipantGrant,
I still have a 13′ x x12′ roll of roof observatory with such a roof. I used well painted hardboard sheets nailed to timber for the walls. It’s still standing and was used for over 20 years and fell into some disrepair as a result of long standing serious illness.
I did find that during the summer the interior got very warm and equipment took some time to cool down. Condensation was never a problem.
I now have 2.7 metre dome on top of a wooden construction for which the dome and metal work (including telescope) suffer from condensation for which I use de-humidifiers that solve the problem.

Eric WatkinsParticipantHi Eliot,
I’d be interested to hear how you get on as I’d like to have a goat setting up a system in a few months time.
Eric
Eric WatkinsParticipantBill,
An impressive short film that captivates what can be done and why I’m very interested in getting into this area of research this coming Spring.
Regards,Eric
Eric WatkinsParticipantWilliam,
thanks for the info. I have the same DIY instructions for making the antenna. Time is really lacking at the moment. The ready constructed source is useful, I’ll see if I can get one to match the DIY specs for radio back scatter.
Eric
Eric WatkinsParticipantThis is an area I’d like to get involved with and introduce my nephew too and set up a double radio back scatter meteor detection station for comparison.
I know that the aerial can be made up, but I haven’t the time at the moment. Can an effective aerial be purchased for radio back scatter detection of meteors or if their might be any members who could make one up for a suitable “donation”?
Thanks,
Eric

yes I fully intend to. I gathered some info on equipment etc. Just need to check that this hasn’t changed i.e. improved cameras. Will try to get a system up and running early in the new year.
Eric
25 November 2017 at 1:40 pm in reply to: Meteor Spectra 2017 Nov – I87 Astroshot Observatory #578804Eric WatkinsParticipantWell done. This is a field I’m determined to get into next year.
The more results I see the more encouraged I am to do so.
Eric
Eric WatkinsParticipantTony,
where did you get your pier from? Looks substantial and I’m looking for one for my Paramount ME II. Their offer is ridiculously priced.
Cheers
Eric
Eric WatkinsParticipantYes Tony, there will be a fair bit of weight in the roof, hence trying alternatives to felt. If the weight of the roof does become too much to easily move then I shall consider using some form pulley system of motorization via automatic gates system.
Erioc
Eric WatkinsParticipantThat looks a good job Tony I’m in the process of building a 4.2m x 3.6 m roll off housing an 16″ F:6 Newt/ME as a 2nd observatory to my domed C14 Edge/MEII.
Could you provide the details of the roofing material you used-I’m looking for something other than felt

I’ve managed to find a met office site that has cloud date over 25Km square grid pattern. I’ll register with the site and see what they have.

Cloud coverage tables would be useful. An area I had looked at is the South West cost peninsular of Pembrokeshire- Dale through to Tenby, but it’s surprising how much of an effect the lights of Pembroke power station and the gas terminals of Milford Haven light up the sky. I was born there and can recall from early childhood a fair bit of rain, but there are stretches that have their own micro climate.
I have also been considering the south west.
Until recently I had thought of Spain or Italy, but with the advent of Brexit, that’s a non-starter.
I’ve not even had a mediocre night at my present location for a couple of months.
