Astronomy and telescopes

Discussion in 'The Pub' at netrider.net.au started by 69SIM, Sep 17, 2016.

  1. Hey all,

    I did a search before I started this thread and found a couple of references and a thread about astronomy and I thought to myself: "Self: Time to nerd up and start another thread", so here we go.

    Been a huge astronomy buff since I was a kid. My dad had this huge book that had all the latest images from all the ground based telescopes (David Malin) and some from the launch of the various Pioneer and Voyager probes. Over the years we collected lots of Nat Geo books with the Pioneer/Voyager planet fly-by's... I was like a pig in mud heaven!



    Wanted to become an astronomer but unfortunately you need pretty good maths and even though I have great logic solving (helped me to become a software engineer) my overall maths and memory is not so good.

    When I moved to Sutherland (The Shire - where all the nasty hobbitses are from *grin*) I immediately joined the Sutherland Astronomical Society (SASI) and thus began the great money pit that is buy and modifying telescopes! Every year we go to Mudgee for a week or so to a private "star party" hosted by the owner of the Mudgee Observatory (who is a SASI member) and 1 of 2 things usually occur, 1) We observe or, 2) it rains and we implement "PLAN B" i.e. quaffing of Mudgee wine :)

    Anyway, enough chatter. Time to post up some images of some of my gear:

    I don't have any photos on the computer of my first serious telescope, but here is one I nabbed from the internet. I had this scope for 10 years or so and it was a great little scope, could easily see a decent amount of galaxies in it under a dark sky (i.e. not in Sydney). It's a Celestron C8 SCT on a fork mount, 8" mirror, Schmidt Cassegrain Reflector:
    celestron_super_C8plus.

    I then upgraded when I turned 40 to the bigger brother but with the added bonus of it being a computerised Go-To scope. Enter what you want to look at (or it's coordinates) and off it went. This was a fantastic scope, the optics were really good but the Go-To system was a bit awkward to use. It's a Celestron CPC9.25 SCT on a Alt/Az mount, 9.25" mirror:
    IMG_0239.

    2014-06-04 14.52.53.

    A couple of images I took through the eyepiece using the iphone with this telescope... they are pretty poor quality but you get the general idea:

    Saturn:
    IMG_0236.

    Mars:
    IMG_0064.

    I then decided to get a big boy telescope. This is an Orion 14" Truss Go-To Dobsonian. This has the most superb optics. Unfortunately it was a new model and the Go-To system was a piece of sh*t and it's currently in a state of not working (though I can use it as a push scope) until I get around to getting a new mount build for it:
    2012-04-20 08.43.49.

    Without the shroud on (I have added a new computer/controller in this shot):
    2012-07-23 17.34.55.

    This is an interface I built when the base started playing up so I could use the scope in push mode without having to fk about with the original controller. I am using an iPad with some astro software to monitor the scope:
    2012-10-13 17.22.35.

    Along with the scopes (I only have the 14" one now) there is quite a few eyepieces, finderscopes, green laser pointer (which I am legally allowed to carry with my club membership) and dew control.

    For the past few years I haven't taken the scope up to Mudgee (rode the VStrom up one year and the others I've been helping a friend do some astro-imaging - now that's a money pit!). We did this shot of the Orion Nebula, Flame Nebula and Horsehead Nebula a few years ago. I was only learning how to manipulate the images so it's not the greatest but you get the idea:
    M42_Horsehead_Stacked_Adjusted_Cropped_Poster_SMALL.

    Thanks for reading.

  4. I've got an 8" reflector on a dob mount.
    For while I had a camera that I could get to focus on it (Point Grey something or other), but I'm struggling to find any pics.
    Here is one of the 2014 lunar occultation of Saturn, shot with my iphone (through the eyepiece I guess). That's Saturn at bottom right.

  5. The sun in white light using a dslr and 600mm lens with a solar filter. Sunspots and a bit of other structure visible.

  7. My first Ha (Hydrogen Alpha) images through a Lunt solar telescope, one in B&W and the other in approximate colour.
    The camera was my Nikon 1 V1 and these are single exposures. Much more structure visible in these Ha shots.

  8. And finally a proper stacked shot from the Point Grey camera on the Lunt solar telescope.
    Much more structure and features visible in this type of image.

  16. Yeah, I'd wanted one for a while, then found one secondhand at a fair price and grabbed it.
    I've since sold it, had it destroyed by Aus Post and got the money back from insurance.
    If you get a chance, get one. Mine was the 60mm pressure tuned model with the added double stack etalon. Really good once I got it on a decent tracking mount.
