    Poll: autoguiding

    Hi there! As I already mentioned somewhere else, I'm working on a new imaging software, (https://github.com/GuLinux/StarQuew in case you want to be an early tester) which is web based, and therefore ideal for lightweight setups (Star Adventurer + Raspberry Pi, for instance). At the moment there's no autoguiding capability, and I'd like to add that in the future, but this raised a question: how important is considered autoguiding nowadays, and how many astrophotographers actually use it? Traditionally I've been taught it's quite important, almost indispensable, but nowadays the advent of these lightweight mounts, and more importantly the new CMOS cameras which perform quite well stacking lots of relatively short exposures might render autoguiding less important. What do you think?
  2. Stunning entries, congrats everyone!

    DS vs Planetary Imaging?

    Sorry, I didn't read you already have a planetary camera.. that settles it then

    DS vs Planetary Imaging?

    I'd say they're opposite in many aspects. For DS you need a large field camera, while acquisition speed doesn't matter. It doesn't even have to provide USB connection (a DSLR like yours saving to SD card can be sufficient). For planetary, you need a fast (USB3?) camera, acquisition speed is the most important parameter. A wide field would be nice to have, in theory, but it would slow down acquisition, so usually planetary cameras have a much smaller chip size. Telescopes side: for DS you need fast scopes (F/4, F/5), since you need to maximize the light acquisition. On planetary, on the contrary, you usually use slower scopes (F/10) with focal extender, up to F/20 or F/30, in order to get the highest possible magnification. Mount side: on DS you need precise tracking, autoguiders to correct every error. Planetary imaging doesn't even strictly require an equatorial mount, and it could even be successful with a manual alt-az mount (Dobson et similia) With your setup I would indeed suggest planetary/lunar over DSO. You already have the camera, alright, but you'd need to buy much more stuff to get it ready for DSO imaging, while for planetary you'd just want to buy a fast planetary camera (they're usually not that expensive) and you're all set.
  5. Well, not yet for smartphones (or to put it better, it's compatible, but not optimized), but tablets should be ok. It's a low priority goal, but I'd probably concentrate a bit more on functionality first
  6. Hi all, I'd like to share with you a first beta version of my new software. You can think of it like an "Ekos light": a web based INDI client and sequence generator, particularly suited for embedded environments like the Raspberry Pi. You can find a the software and some docs about installation in the github page: https://github.com/GuLinux/StarQuew Please share your thoughts and feedback

    ZWO ASIair

    Seems so, yes.. they really didn't give enough details, but that's definitely a raspberry pi... Not sure if it's gonna be INDI based though, as that would imply that they'd support other camera brands as well, as long as they work with INDI. But anyway, I'm just in the middle of implementing something very very similar...
  8. Hi, It's a bit hidden, but what you need is the "Motor controller firmware loader" that you'll find in this page: http://ca.skywatcher.com/download/firmware/motor-control-firmware/
  9. Unfortunately there's no setting on it to force a clear sky I was able to do a couple of tests from the city, the best of which was this: https://www.astrobin.com/333208/?nc=user Slightly overprocessed, and with a huge amount of light pollution, but gives an idea of stars size, residual CA, etc. Overall, I think I can be very satisfied. Waiting for a real test though!

    INDI on the Rocks

    You swapped the nicknames, but yes, that's what I was meaning

    INDI on the Rocks

    It's not silly, but I can guess the reason: with your setup you will need your laptop to stay always connected to the Rock64/Raspberry server, otherwise it won't be able to shoot on its own. I'm currently working on a web INDI sequence to get rid of this requirement though (and all the VNC setup as well), stay tuned..

    Raspberry Pi 3 Model B+

    Yeah, that's a bit odd.. I run the ASI 1600MM which has a higher resolution, and your is a USB2 only camera, meaning it's *meant* to work at that bus speed... I'd say it's more likely a library issue, either by the INDI driver side, or the Starlight Express SDK lib (hard to say without more data).

    Raspberry Pi 3 Model B+

    There should be a list of UK resellers, I usually buy from pimoroni or thepihut

    Raspberry Pi 3 Model B+

    I might get one anyway, but yes, the missing USB3 is a downer. I got the Odroid XU4 for that, but it absorbs too much power for portable usage

    My TARDIS observatory in the snow

    I would ask you how your equipment fits inside that, but I think I kinda know the answer...
