Astroberry, KStars + AVX mount help
callump replied to lw2689's topic in Discussions - EEVA Equipment
You might want to try plugging the USB -> Serial into another of the Pi's USB sockets. As James says - try running an lsusb to see what devices have been detected. Have you got anything else plugged into the Pi? /callump -
Hi Mike, I'll post a write-up of the setup into the Discussions in the next day or so. Callum

I often get Safari tabs being reported as "this site is degrading performance" (or something like that) - quite often Facebook but a few others too. I was getting a MacOS crash, which seemed to be happening when switching from one tab to another - but it was not clear if that was the cause or not. I switched ti Chrome for a while, but having to re-enter site passwords was a pain, and Chrome has this lazy page loading which is annoying. I found an article about McOS crashes which poked a finger at Energy Saver | Enable Power Nap - switched that off and no more crashes. Still sometimes get slow Safari tabs though. I'm not sure it is much worse or better than 6 months ago though... I presume you are on the latest release of Catalina? Sorry - not much help I know... /callump

Thanks Martin, well, here is the Pal 10 image - negative view. Pal 10 is at the centre and I think you can make it out - certainly it is right by the astrometry.... Callum

Last nights sky was pretty rubbish, but I thought i would see if the 'new' setup would work better than my last attempt having fixed the back-focus 'problem' I had before. All taken with a C11 and 0.63 FR, and ASI174MM mini camera. All 12 x 10s exposures, stacked in Siril. No darks or flats (obviously from the images...). Tried also for Pal 10 but not a good enough image to share here (just about visible with extreme stretch), and NGC 7006 but the cloud had closed in too much by then. M27 M57 M71 /callump

Astronomy Clubs near Camberley/Farnborough?
callump replied to Gmx76's topic in Getting Started General Help and Advice
Cody AS have an observatory at what used to be the RAE - they have a very nice 6" Zeiss Coude refractor. /callump -
I use two Raspberry pi's running IndigoSky (one for the mount, one for cameras), and the CLoudmakers apps for telescope control and imaging. Polar alignment with PHD2 (Polar Drift Alignment is what I have used, but there are two other tools in PHD2). For post-processing I have most recently been using Siril, and then final tweaking in Affinity Photo. All these are MacOS native apps. /callump

Help for a lost soul with very little astronomy experience.
callump replied to Mackem's topic in EEVA - Discussion
I has been thinking about getting a Night Owl, but it is looking like it wont be in stock until 2021 now... /callump -
Linton, I used matt black Correx - its a bit thicker (with hollow cores) but works ok imo. Callum

I've been using IndigoSky for a little while now - it all seems to work pretty seamlessly as a server. All controlled through a simple web page. (I did have a problem connecting to my home WiFi network but that was fairly easily solved). /callump

LX200 protocol implementation (Python)
callump replied to freiform's topic in Discussions - Software
If you are talking about the LX200 classic - then the communication protocol is just an RS 232 serial link, 9600 baud. If you mean the commands and responses, these are documented in the back of the Meade LX200 instruction manual. There is also some sample code, but in Basic so maybe not directly usable... Callum -
I made a very successful finder using a pin rather than cross-hairs. The tip of the pin (or needle) is placed at the center, and in use it does not obscure the object you're aligning on (if you get my point :-) /callump
