  1. Raising my DIY game with this machine

    That's very compact! And it seems to be very versatile... Let us know, I'll probably think about it myself..
  2. Planetary Setup - Feedback/help required :)

    With a high focal ratio as yours (F/10) I'd choose a different camera with small pixels, like the ASI 178. This would allow you to get to the limit of your telescope resolving power, but without using the barlow lens. It's the same setup I use on my Maksutov, I have a slightly higher focal ratio (F/12), but it should be ok in your scenario too. I'd also prefer mono cameras over colour, but that's another story... If you can't buy filters and filter wheel now, you can always start with mono imaging, and buy them later on.
  3. Canon d700

    I have the 700D, and it's a pretty nice camera, but surely not the best you can buy for planetary/moon. I use it mainly for wide field astrophotography and obviously daylight as well. The best option for moon (and planets) is a dedicated, preferably mono camera, particularly for the moon, since you'd probably discard any color info anyway. ASI cameras are widely used, well supported among all OSes, and relatively cheap.
  4. Well my reply to that is pretty easy, usually... I reply with another question: "How far can you see with your naked eye?" And that's when they start to understand how it works.. since they might at first reply "a few kilometers", but then, what about the moon? Or the sun? or naked eye stars, by the way, and even M31....
  5. Time to say goodbye :(

    I can understand very well how you feel, less than 2 years ago something quite similar happened to me, when after some observations I left my equipment in my car, and almost everything got stolen. Not as expensive as your equipment, I guess, but still, more than a couple of thousand of euros worth, and I too did spend a lot of personal time improving things doing some mods. I think you'll probably benefit from a break. I'm pretty sure that when you'll be ready again, and the thought of it won't upset you anymore (well, not that much at least), you'll find a way forward. In my case it was... well, I wouldn't say "beneficial", but I was able to get new equipment more suited to my needs, focusing on transportability and lightness. I really hope you'll be able to recover as much as you can, and the best of luck on whatever you choose to do.
  6. Hello from Bodmin Moor - new Dark Sky area!

    Welcome Hope to be visiting your area in the future, seems to be an interesting observing place!
  7. What Guide cam for Linux

    Hi, Your setup reminds a bit of mine: I have the shooting software implemented as a python module + script on a raspberry pi piggy backing on a headless INDI server. Main difference is, I don't use any autoguider (yet). Here's the code: https://github.com/GuLinux/indi-lite-tools/tree/master/pyindi_sequence The main repo also includes a raspberry pi setup script, a webserver with some logging info, and various API/addons (for instance, I also print status on an OLED display). Strictly answering your topic: ASI cameras work pretty well on Linux - among the best I've tried, I'd say. The ASI120 in itself is a bit of an exception: for many users it just works, but apparently some models do need a firmware update before, and some other models seem to refuse to work at all. I might have incomplete/outdated info though, just go to the ZWO forum and do a quick search. It would be pretty difficult to get image directly in python though, as they don't support the V4L2 interface. You could however use indi (+ my module if you like). I might be interested if you can get an autoguider algorithm with python and opencv, the autoguiding feature is the main thing missing in my scripts, if you'd like to contribute it would be cool. Cheers, Marco
  8. Hi, No, it was dev2, unfortunately I haven't had more time after that. I'll try with a bigger rotation then Anyway, it's not a guide scope, that's the point! I'm trying to do something quite similar to the polemaster
  9. Hi, Quick feedback from me: The interface needs some refinements, but you're on the right track I tried using this with an ASI 178mm, and a 25mm lens. I know it's quite a short focal length, but it's more or less what the PoleMaster uses, so I'd say it might be worth implement support for such wide field of view. Right now, there's no way to zoom in, I've tried to do the polar alignment procedure anyway, but the app crashed on the third rotation. Still, I know it's kinda of an edge case
  10. m33

    Well, probably a little less denoise would improve it (did you use a mask?), but otherwise, I like it a lot. Very nice stars in there, tiny and coloured! What equipment (and processing SW) did you use?
  11. Star adventurer mini Eq3-2

    Oh ok.. that makes much more sense... sorry
  12. Star adventurer mini Eq3-2

    The star adventurer can hold up to 5 KG, according to specifics. This might already be stretched, I would say the ideal maximum payload weight would be around 3 KG. I don't know exactly what the skywatcher 150 is, but the best guess (the explorer 150p) is a 5 KG OTA without any accessory (you'd probably want to put a camera on it, I guess, plus adapters, and a heavier counterweight, an autoguider, even an OAG with a secondary camera is still some decent weight added). Plus there's the matter of the focal length: for various reasons the best focal length for the star adventurer is under 300mm. You can stretch it to 400, if you use RA guiding, but since it doesn't have DEC motors, that's about it. The 150p has a 750mm focal length. Way too much for the Star Adventurer. You'd have to reach an extremely precise polar alignment, and even then, it probably won't be enough. In summary, no, I'd really recommend to buy something else for astrophotography. The star adventurer is a really handy and versatile mount, but not that versatile.
  13. This was helpful, I was wondering just the other day what that hole was for!
  14. Hi everyone, Just a quick notice about 0.7.0 release: http://blog.gulinux.net/en/planetary-imager/downloads Unfortunately there are no great news since the latest 0.7-beta3 version, didn't really have a lot of time lately, but a lot of bugs were fixed in the meantime, including some more testing on the OSX and Windows version. QHY support has been temporarily dropped, since their SDK is being updated in the meantime. Lots of interesting stuff will now be implemented for 0.8, so keep tuned!
  15. Cool, definitely waiting to be able to test it then!
