My first (worth shouting about!) astrophotograph – Pleiades

So, a year since starting this hobby I can finally show something that I’m happy to post.   Hopefully it’s recognisable!

It’s a bit basic for all you battle-hardened astrophotographers, but it’s my baby, and I’m a proud father 😀
(Disclaimer: It’s only a 3.5Mb export from GIMP, so the quality here isn’t optimum; I tried uploading a slightly larger file, but got errors)

Whilst building up my kit I’ve aimed for a light(ish), portable, standalone setup, so I’ve gone through the educational tribulations of setting up and getting to grips with StellarMate on a Raspberry Pi simply because it appeared to be a one-stop-shop rather than a pick-and-mix of various applications and tools.  And us geeks like to tinker 🙂

In the past I’ve had problems with using its Polar Alignment tool, but it transpires that muddling by with the wrong cable, thereby under-amping the Pi, meant that for the price of a nail the battle was lost.  A 2 quid Amazon Basics cable meant that last night was my most successful ever.  The Polar Alignment tool worked a treat, and it was only at breakdown did I realise that the I’d left the Dec clutch locked all through the session, so the fact that I’ve not got any (overly noticable) star-trailing can only be down to the polar alignment (someone please correct me if I’m wrong).

Onwards and upwards.  Orion Nebula and Andromeda are – clouds notwithstanding – in my sights!

  1. I have slightly re-categorised your post to fit in with the website policies on categorisation – which should be one category for your name and another for topic – when you choose a subsidiary carry then you don’t need to choose parent category as searches will work with both anyway (so here you did not need astrophotography (parent category) as well as astrophotography-deep sky (child category) = the child was sufficient).

    1. Apologies; I couldn’t find anything like a FAQ or a guidelines doc, so I took a punt at some appropriate categories. I also didn’t see anything that allowed me to create new categories, so assumed that it was something that WordPress picked up from your login/profile.
      Maybe I didn’t look hard enough?

  2. It is amazing what can be achieved with unguided exposures – thanks for posting!
    Please state the object you be photographed in your posts for prosperity. You might like to add a comment now to say what it is.
    I am really interested in what you’ve done with your Raspberry Pi – not something many members have considered. Coukd I ask you to publish another post describing in detail (and starting simply for idiots like myself who don’t find these things easy to understand) how and why you’ve used a Raspberry On and how it has helped you?

  3. Great stuff Darren- it’s immensely satisfying when you get your first one and it’s really clear what it is.

    I’m really impressed that you’ve gone down the Raspberry pi route- I’ve read quite a few good things about it, but never quite plucked up the courage to tackle the learning curve!
