    If you are wanting to image planets / Moon you probably need to connect the camera to your laptop.
    There is a MacOs version of Firecapture that works well for me.

    If you want to connect by WiFi you’ll need some sort of computer attached to the camera – something like a Raspberry Pi with INDI or Indigo installed can work if you want to take longer exposures. But does not really work well streaming video.
    Or you can connect a ‘standard’ computer to the camera and use some sort of remote access app (like VNC) to control it remotely via wifi.

    Hope this helps.

    My current favourite star atlas is the interstellarum Deep Sky Atlas

    See: www.deep-sky-atlas.com

    Its available from Amazon and other places – it is a bit expensive, but it is a really nice, easy to use atlas.

    Thanks David,

    I don’t read MagPi as much as should – good articles there.

    Yes, they got in touch with my local society too – and one of our members (Peer Cadogan) will be appearing on the piece and be talking abut EB. Unfortunately John Harris (who is also a Cotswold AS member) was away in France at the time of filming.

    Thanks for the feedback Bill & Ronan.

    A very enjoyable weekend, I thought, and much thanks goes to all who did the real organising of the event.

    And it was great to meet up again with so many astro-pals.

    Cheers,
    Callum

    I have aligned fits images using Python, AstroPy and the astroalign package.

    If interested email me, and i’ll send a fairly trivial example python script.

    Nice looking obsy BTW.

    Cheers, Callum

    Thanks for alerting us Bill – actually the CPRE got a little ahead of us, as this is a joint BAA / CPRE project that we have been working on for the past couple of months. Helpfully the CPRE kindly offered to host the website submission forms and process the results.

    I hope members will take part, and spread the word to their local societies, forums, and encourage friends and families to take part too.

    Many thanks for the feedback on the livestream – this was just the second time the IoP tech team had done this form their new HQ and a first for the BAA. 

    Sorry if finding the link was a little tricky (thanks Lars for posting) – we’ll take this as a learning point for the future.

    Everyone – have a very Merry Chrsitmas.

    Hi Paul,

    you are not the only weirdo on here – I use mainly Macs and also a couple of Raspberry Pis with Linux – and i’ve dabbled with other Linuxes in the past.

    For convenience, though, I do use Mac version of MS Office…

    Maybe you looked at the ImageJ photometry tutorial currently on the front-page – ImageJ is cross-platform and should run well on Linux/MacOS.

    But sorry not able to provide much in the way of practical help on any VSS questions. But you certainly have my moral support!

    Clear skies,

    in reply to: Longest focal length eyepiece #580032
    Callum Potter

    There are some eyepieces with a 3 inch barrel diameter.

    There is a ‘short’ 30mm from Explore – which I saw at a show last year – a monster of an eyepiece.

    But there is also a Japanese 80mm eyepiece available from APM – but not cheap – though if you have €2k spare…

    Of course you need a scope with a 3″ focuser too…

    Having examined the governing document, affiliated societies do not have a vote – any vote from an affiliated society will not be counted.

    Voting is open until October 15th, so still time for members to get your vote in – either electronically or by post.

    Thanks,

    Hi Xiaoli,

    M64 sits in the constellation Coma Berenices, which is a bit low in the sky setting in the west at sunset, so is pretty much un-observable at the moment, and I think that remote robotic telescopes in the northern hemisphere won’t allow you to observe that low.

    Really it is a Spring constellation, though might come into view for imaging Feb onwards, depending on the telescope location.

    If you are at school, you could try to get them to get you access to the Faulkes Telescopes, which have some nice big robotic telescopes.

    There are a lot of galaxies available at the moment, so you might need to pick a different one depending on your project needs.

    Best regards,
    Callum

    Hi Grant – currently working on it – will let everyone know once it’s confirmed. Probably Birmingham area, though.

    Hi Andrew,

    always difficult scheduling meetings – the calendar gets pretty congested at some times of the year. 

    The annual programme is usually fixed up up to two years in advance, and the Sept meeting is usually the first weekend of Sept.

    Winchester next year is the same weekend as Spring Kelling (only weekend the College is available).

    BTW have penciled in March 23 for the Deep Sky Section meeting next year – assuming there is no major conflicting event. Location TBD.

    I can never remember if arc-minutes and arc-seconds are ‘ and ” or vice-versa!

    Does make hunting for some objects rather problematic!

    Decimals are used on iTelescope plans, so conversion is usually needed from catalogue and internet sources…

    Hello Graham,

    though probably most local societies will not need to register (and pay a fee to the ICO) it does not mean that you don’t need to follow the regulations.  The regulations apply to all businesses and organisations that process personal data – whether electronic or on paper.

    Registrations are just the way that the ICO is funded, and the exemptions for small clubs and the like are more or less the same as under the old law.

    So I am afraid it is not a silver bullet.

    Regards,
    Callum

    Good luck with the project Edward – I will look forward to seeing your results.

    It would also be interesting to hear about your experience with the Hyperstar – an idea article for the Equipment and techniques section.

    All the best,
    Callum

    Another Hyperstr user is Grep Parker who spake at last years Deep Sky Section meeting – though not all about the Hyperstar, though he did mention it in the task. Hopefully this to the video link will work: https://britastro.org/video/7951/9337
