  1. Being on furlough from work has meant I've been able to put some effort in to some Raspberry Pi projects, but not astronomy related unfortunately as I had to retire due to some very large trees. Here's my Pi 4b 4gb with a fan hat & rf transmitter hat on top. I've been working on a project with 2 radio controlled sockets to control my darkroom enlarger and safelight from the Pi. I used Node Red which is a very simple and intuitive programming environment that works well for this type of thing. Here's my control dashboard that I can access from my phone when I am printing.

  3. Very impressive, I've not visited the DSO imaging forum for a few years and you have certainly upped your game while I have been away. Beautiful image.

  8. Hello, Nope, never had a problem with this sort of thing. I used to bin all my RGB 2x2 and shoot a master flat using the Lum filter only at full resolution and then use Pixinsight to register it to the binned images. Sorry I can't be of more help. Would have to be a fairly bright red light shining directly on to the scope from somewhere to be a light leak.
  9. I used the 1.25" Cheshire back in the day when I was using my 6" RC.
  10. G'day Kirret, Stick to narrowand imaging with the modified DSLR, you can get a clip in Ha filter and extract the red channel of the image to get a pretty decent mono Hydrogen alpha image. How is the mount doing? Have you got it up & running now?
  11. let it lapse I'm afraid Lee, I've had to retire from the Astro imaging business due to several very large oak tress on National Rail property
