Although on a remote Scottish island, we get post deliveries every day except Sunday by Royal Mail, the only disruption occurs when the weather is too bad for the boats to sail. Mostly 24hr mail arrives next day or a day after, and on the whole it is the preferred method. DPD / UPS / Evri etc. go to Kirkwall and then our local agent picks those up and delivers three times each week. Callum

Here's an article about capturing cosmic rays with a DSLR: https://britastro.org/2023/capturing-cosmic-rays-with-a-digital-camera Callum

A nice double arc last night. Clouds came in afterwards stopping play. This is a composite of two frames, 10s exposures, ISO3200, 21mm, f/2.8. Callum

Aurora from Orkney on December 1-2
callump replied to callump's topic in Imaging - Widefield, Special Events and Comets
Thanks Paul - not sure what went wrong there! Callum -
Noticed rays and colour on the aurora-cam (webcam) with the sky not properly dark. Some significant action from 17:30 to 18:00 when the display calmed down and weather started to close in. Some massive rays and corona visible. /callump

A spectacular display of the northern lights on Orkney, started around 18:15 and kept on going until midnight. Multiple bands and patches reaching even to near the southern horizon. Lots of nice ray action. Just a few of the approx 500 pics taken. Sony A7s, Loxia 21mm lens at f/2.8, ISO4000 (don't ask), 3.2 or 2s exposures. No post-processing. A memorable night. /callump

On Orkney, was a great show earlier but a bit quieter now (21:40) - though still a nice double arc with rays and structure going on. Will need to get another splurge if it's going to be seen from further south which may happen, and with the Moon rising will get in the way. Pics still on my DSLR but here's a recent shot from my aurora-cam.

Not sure where I heard, but there should be plenty of stocks of RPi4s in June. /callump

For most auroras at northerly UK locations, a display is just white/grey to the naked eye. On occasions when the aurora is very intense red colour can be seen. Which I have seen from Orkney and from Gloucestershire. Cameras do pick up the colour well, but the apparent intensity depends on the processing done. I try to minimise the processing to achieve a more restrained presentation. We had a very bright aurora on Orkney on March 23, and I also took some real-time video - though it still shows some green / red tinges it is a pretty good representation of what the naked eye sees. I made a video of the display at: /callump

Not one of Martin's brews 🙂 Used to be the Red Lion, but we always went to the Crown (if drinking in Goostrey). /callump
