  1. 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!
  2. 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 I might have incomplete/outdated info though, just go to the ZWO forum and do a quick search.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
  3. 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
  4. 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

    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?

    Oh ok.. that makes much more sense... sorry
  7. 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.
  8. This was helpful, I was wondering just the other day what that hole was for!
  9. 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!
  10. Cool, definitely waiting to be able to test it then!
  11. Cool.. pretty much what I was looking for I might try to contribute, although I have no previous experience with wxWidgets. Does it also work with a large FOV, like the Polemaster itself? I have an ASI 178mm with a 25mm c-mount lens, I was planning to use that as a polar assistant tool. This might be a problem: as I stated before, it should also work for manual mounts (like the Star Adventurer, the RA motor is way too slow to rotate a decent amount of degrees). Do you support, or plan to support, manual mount rotations? Cheers, Marco
  12. Interesting, I'll give it a go. Is this somewhat similar to Firecapture and Ekos polar alignment modules? I was about to start coding something similar as well, since Firecapture is Windows only, while Ekos tool has a quite "restrictive" workflow, designed for automated observatories, and quite difficult to adapt to a StarAdventurer, and I wanted something much closer to Polemaster. I certainly hope yours will suite me Just a question: any particular reason you shipped it with PHD2?
  13. I made up my mind: just bought the TS Photoline 60mm. It was a really close match with the WO 60mm, but I'd rather stay safe with the lower focal length.. I already have enough trouble with polar alignment with my current 200mm!

    Well of course, but I was mainly referring to myself: I don't have any flattener/reducer at all, so I might as well buy the right one from the beginning Be aware that the flattener listed in FLO is only a flattener, not a reducer, hence you'll have a bigger focal length. I'm trying to make up my mind, but I'm still very undecided between the WO, and a couple of TS-Optics photoline scopes (a 60mm F330, which I'd prefer for the shorter focal length, but it's a bit too much expensive compared to the WO, and the 72mm F400, only slighly more expensive than the TS 60mm, but of course heavier and with an excessive focal length for the Star Adventurer). But on the TS scopes there's this focal reducer listed: https://www.teleskop-express.de/shop/product_info.php/info/p10025_TS-Optics-PHOTOLINE-2--0-79x-Reducer-4-element-for-Astrophotography.html As you can see from the description, depending on which scope you use it, you just need to adjust the distance between the reducer and the camera. Maybe the same applies to your WO reducer? That's another thing I'm very interested into Pictures without the reducer... I have an ASI 1600mm, so smaller chip, maybe I could do without it as well

    Interesting review, I'm evaluating this for myself as well. Do you think the defects in the border are due to the reducer not properly fit? As far as I know they have to be at a precise distance from the camera, depending on the focal length...
