    There's gotta be a couple of us kicking about in the forums. I know of at least one other. Might be good for a more southern hemisphere biased place to discuss.

    I have only been dabbling for a few months since I got my gear. It's been pretty disgusting weather since so haven't had too many decent sessions. yet.

    Current hardware setup is:
    • Skywatcher HEQ-5 Pro mount
    • Skywatcher BD ED100 900mm refractor scope
    • 0.85x field flattener and reducer
    • Piggybacked ZWO 280mm guiding scope
    • ZWO ASI 120mm autoguider camera
    • Literally the cheapest Windows 10 laptop I could find with 64gb hdd to run all the control apps (Acer Spin 11 I think it is)
    Current software:
    • Astrophotography tool
    • PHD2 Autoguiding
    • EQMod
    • Stellarium and StellariumScope
    • Pixinsight for all the processing.

    I don't really have a decent image to share yet. I've been focusing mainly on Carina Nebula for the time being because it's big and bright. I managed to get about an hours good exposure time one night and then 90min more exposure time a second night but being a noob I forgot to check my field rotation and can't integrate the two sets without losing a fair bit of periphery :(


    Please tell us what you have!

    Awesome to see you posting!

    We have similar setups as you know Holden. I currently have the following:
    • Skywatcher HEQ-5 Pro mount
    • Skywatcher BD ED80 600mm refractor scope
    • Piggybacked ZWO 280mm guiding scope
    • ZWO ASI120MC-S USB3.0 Colour
    • I am currently hoping to use my Surface Pro 3 to run it all, but with only 1 USB port I'm not sure it will work out unless I use a powered hub (reducing portability)
    I had a lot of trouble getting my guide scope focused, but finally managed to get that sorted...just in time to hurt myself at work. With 3 fractures across both arms, I don't have the strength to play and probably wont be able to for another 3 weeks or so. The concussion I caused myself at the same time has definitely addled me, as I have been struggling to sort out the software while I'm incapacitated and struggling more then I should be!

    Anyway it would be great to see if anyone else is around, post your location if you are too, might be worth a meetup if anyone is relatively close by!

    EDIT: I'm In Liverpool, Sydney

    Damn! That's a terrible thing to happen, mate. I hope you heal quickly!

    I was going to PM you and see how you were going but decided I'd just make the thread.

    Surface Pro 3 at least has a USB A style port though yeah? Could be worse and you need to use a USB C hub. I wouldn't trust one of them as far as I could throw it in my experience with the ones on my Macbook Pro.

    I'm in Oxley, Brisbane.

    So i picked up some loan gear from a friend, Celestron CPC 1100 - 11inch Cassegrain, Alt Az fork mounted with goto, but with a wedge, so hoping i can still take decent photos!

    So much to learn!

    Hey guys, i'm at 90% health now, and starting to play again. The guide camera is completely useless, and I will be getting a replacement in the m,ail over the next week or so (it was broken as I originally thought)

    The wife and I are going for a drive from Sydney down to Mungo National park at the end of the month, so hoping to get my gear sorted by then so I can have a good time in with the dark skies!

    Any thoughts on a ZWO ASIair ? (https://www.bintel.com.au/product/asiair-asi120mm-mini-kit/?v=6cc98ba2045f ) Looks like its about to get polar aligning, and looks pretty compelling to me!

    Only immediate issue for me would be that you would need a ZWO main camera to get the most out of it, although it would solve the issue I have with multiple USB ports on my Surface Pro 3 (Use the SP3 for imaging from my Canon's, control and guide from tablet)...hmm, decisions decisions

    I'm not a fan of proprietary all in one solutions. I much prefer my cheapy laptop I bought for just $299 which will let me run any mix of apps and gear I want.

    ASIair is one hell of an expensive raspberry pi.

    It's been months since I've managed to get outside and image :( Towards end of summer I was dewing up really early in the evening and it's been rainy/cloudy as lately.

    I hear you on that, but the fact that it IS a pi makes me feel like it's less proprietary.

    Shame I can't find an image of the OS somewhere to test it out

    Which is one of the problems I have with it.

    I think something like windows laptop + indigo when it's in a usable state will be a better fit for controlling the gear from a tablet/phone.

    Trying to get Stellerium +Stellerium scope up and running at the moment, it is a bit painful, do you need to have an autoguider for it to work properly?

    Hi All,

    I go in and out of my interest and its either because of the weather, or how much free time I have to do it. The struggle is also between wanting to do some visual or photography too! I have only ever imaged from my metro backyard.

    My setup is:

    Meade LX-90 8" ACF
    0.66 FR
    2" Diagonal
    Losmandy counterweights
    QHY8L CCD
    Canon 40d on piggyback
    Raspberry Pi running iAstroHub (for remote access/control)

    Cats Eye

    I am starting to get the itch again and as the weather warms up I think will be getting back out again.
