    Hello Sheridan,

    Can the scope have an imaging camera attached? One way of checking rough polar alignment with an ME is to note the precise time (to, say, a few seconds GMT) when homing completes and the sidereal tracking starts. Then, immediately take an exposure of, say, 60 seconds. If there are plenty of stars on the image upload it to Astrometry.net and it will calculate the precise field centre. For an ME it should home at 0 dec and 2 hours past the meridian at the time you homed it. Of course this is somewhat dependent on nothing going wrong with the homing process (you get the bongs, so that is encouraging) and also the telescope being mounted parallel to the Versaplate…… It also assumes there are no trees or buildings from your site that are over 30 degrees high at an azimuth to the SSW…. Astrometry.net will instantly tell you if the field centre is far from zero degrees Dec. The sidereal time from the observatory at the time tracking started, minus two hours, should tie up with the R.A. calculated by Astrometry.net.

    It’s a simple test that should give you a rough idea how far off the polar alignment of the mount might be.

    Despite trying for over a year we have been unable to get our telescope’s Paramount ME set up accurately.
    If anyone is willing to come and assist we would be eternally grateful. We are based in Milton Keynes.

    Hi Connor,

    Supernova are too distant for any change in their distance or location to be measured. Though monitoring the changing brightness and spectra of brighter supernova is frequently done by members of the BAA Variable Star Section.

    I attach a plot from the BAA Photometry Database of SN 2026kid, photometry again by Ian Sharp.

    Robin Leadbeater is an expert at obtaining spectra of supernova. This is tough for amateurs as supernova are faint and typically require large telescope to obtain usable spectra. Here are a couple of spectra from the BAA Spectroscopy Database of SN 2026kid by Robin.

    Hi Dave,

    I’m 71 now but in good nick (comparatively!). Able and willing….

    Biggest issue impediment is that I live in Cambridgeshire…

    I would be happy to come up to Newcastle for, say, a couple of days and do what I can. Just need to sort out some dates, I guess.

    As I say, I’m in contact with a couple of ex-Newcastle guys – at least one of them may have been a user of the telescope (we shared Hugh Battey as a PhD supervisor) and another was a frequent visitor to Ken (Keith?) Runcorn’s so-called ‘field-free building’ (for geomagnetic measurements) which I believe was on-site with the observatory.- I’ll send this link around and see what happens.

    I would absolutely love to see that visitor’s book!

    Best Wishes and thank you so much for your efforts to save this telescope.

    Two images of the spectrum of the nova tonight in very difficult conditions. Just a handful of images possible through gaps in the cloud so not great.
    But wow!…what a change in just a few days. A very boring continuum on 26th and now really wide and bright emission lines. [They get wider towards the blue end (H gamma) due to the non-linear dispersion of the prism].
    Mike.

    Hi Trevor,

    How can you help? Firstly, we’re always after bodies to help us move the heavier items. If you’re fit and able-bodied (The terrain is not kind on the ankles) then get in touch and we can discuss.

    I am really keen to hear from former Newcastle students who used the telescope in its prime. They may be able to assist with project documentation, historical context and, in particular, observing logs. We have the Observatory Visitor’s book although this wasn’t filled in regularly. We’d love to know who used the telescope, when and what they observed.

    Another update:

    We launched our crowdfunding project on 28th August 2026. Two days later, we reached 75% of our initial goal of one thousand pounds. That’s tremendous. We now have enough money in the kitty to get the mirror re-coated.

    On 27 July, as part of my asteroid occultation work with my remote telescope in Galicia, Spain, I noted an interesting feature in the lightcurve of an occultation by asteroid (8007) of the star UCAC4 354-170588.
    Following subsequent analysis and peer review, CBET 5730 has now been published, reporting the discovery of a satellite of the asteroid.

    Jim Wild, RAS President, writes:

    “The Royal Astronomical Society welcomes an upcoming debate at the Houses of Parliament about cuts impacting astronomy and encourages all Fellows to contact their MPs to urge them to attend.

    It will take place on Tuesday 1 September from 1-1.30pm in Westminster Hall.

    Last month it emerged that measures to address a devastating funding crisis will put a wide range of UK astronomy projects, facilities and international partnerships under severe pressure.

    The recent warning that astronomy at Jodrell Bank Observatory could end has attracted significant public attention, but it is only one part of a much broader picture. Other internationally important programmes are also threatened, such as UK involvement in the James Clerk Maxwell Telescope (JCMT) in Hawaiʻi, prompting serious concern from the RAS about the future strength and breadth of UK astronomy.

    The consequences of the cuts are only just starting to emerge, and their impact will also extend well beyond astronomy, affecting other strategically important areas of UK science, including particle physics and nuclear research.

    Intense lobbying from the RAS and leading scientists has undoubtedly helped soften the blow for UK astronomy, but the future is still bleak and the cuts so deep that more needs to be done to campaign for a re-think.

    The latest analysis of the impact of the cuts across STFC-funded fundamental astronomy projects is 35 per cent, which sits uncomfortably against the headline figure of the 10 per cent budget reduction to projects quoted by UKRI and is much closer to the impacts originally feared at the beginning of the year.

    RAS President Professor Jim Wild said: “The Westminster debate is a chance for us to continue to make our case.”

    I have written to several of the Cheshire MPs, including the MP for Congleton where Jodrell Bank sits, about Jodrell and the cuts more broadly and have been assured of their support.

    I urge others to write to their MPs.

    Hi David,

    Thanks for the update. I’m glad that some positive progress has been made with saving the telescope and, possibly, part of its dome as well.

    How can I be more actively involved? I am in contact with several contemporary Newcastle students. I’ll see if they can help.

    best Wishes,

    Trevor

    My site was at AlbarracĂ­n. To the naked eye the corona looked golden, which I ascribed to the low altitude.

    Through a 100mm spotting scope at 60x, the corona was a very pale yellow. An enormous prominence on the left (east) limb was a brilliant red. The line on the other limb didn’t extend as far out but was much longer; it was the same colour. As soon as the first Bailley’s beads appeared I stopped watching through the telescope.

    We were incredibly lucky at that site. As the sun set it went behind a bank of clouds at about 40% phase. It reappeared a minute or so before totality and remained in clear sky until sunset. A few kilometres away in Teruel they had the opposite experience: clear for the majority of the partial phase and totality completely obscured.

    An update is overdue. Major sections of the Espin telescope have been removed to a safe place away from the vandals and the Urban Explorers. We were able to recovery both the primary and secondary intact. The primary has suffered following twenty years exposed to the elements. The secondary, still in its protective cover, was as good as new.

    We aim to recover the remaining Ash dome because it’s in good condition and will help with our fund-raising efforts, which are needed to cover the cost of the demolition of the domes and site clearance.

    We will establish a CIC to help manage any costs and, of course, any donations.

    So far, so good. I’ll post another update shortly.

    Best regards

    The view through my telescope of the eclipse. Best viewed with audio on.
    You can see the challenge of doing it on a windy day bobbing around on a rough Greenland sea.
    My apologies for poor manual tracking, I was also viewing it through binoculars.
    Canon 90D + Askar SQA55.

    The latest Astronomer’s Telegram, ATel #17960 details more spectroscopic observations. A bit better than mine….but they do have a 2.0 meter telescope on La Palma…!
    The narrow spectral lines don’t show well at the much lower resolution of my spectrum. But the atmospheric absorption (Telluric) bands are clearer…I’m looking through a lot more atmosphere than they are…(!)

    First attempt at a spectrum of the nova this morning. The sky was starting to brighten and the telescope only just cleared the observatory wall so a very narrow window of opportunity!
    The image covers the same field as the AAVSO chart shown above with the nova near the centre. It shows a strong continuum but little sign of emission lines yet. I guess it is still in the hot, dense ‘fireball’ phase. As it expands and cools the emission lines should appear as the continuum fades in the ‘nebula’ phase…it will be fascinating to follow over the next few weeks.
    As Gary mentions above it is bright. Two comparison star magnitudes are shown on the spectral image.
    The spectrum was taken with a 26cm, 3 degree objective prism on a 12inch F/3.6 astrograph and unfiltered CMOS camera.
    Mike.

    Thanks for this….always good to have a backup plan. Going to have a party with the neighbours fingers crossed, but have to get the telescope on the garage roof first to gain sufficient visibility.
