Stekkar Aurora, Iceland Tuesday 21st February 2023
There was only one real aurora display from a week in Iceland and here it is. Taken from 22.19ut till 23.29ut on Tuesday 21st February. Canon 350D 10mm f4 iso800 30s.
Sunocular Fun Tuesday 21st February
Away in the wilderness of Iceland it was nice to get a view of a hazy sun with the Lunt 8x32 Sunoculars.
These are a great piece of very portable solar equipment that provide meaningful views
All the main sunspot groups were quite easy to see, with the image below approximated what could be seen visually very well.
The end of the day was clear and cold and provided a lovely view of the conjunction of the Moon, Venus and Jupiter.

First Sunshine of the Year 5th February
First solar imaging of the year, and also first iamging with the solar spectrum rg38 0.3a Ha filter on the 100mm f8 APM triplet. TZ4 was used to get to f32 with the camera being the FLIR IMX174. Sky conditions were thick haze and these were taken with long exposure and very high gain just to punch through it all, very pleased with the results given this. Very much looking foreward to being able to use this new setup in better conditions.

Calcium Proms 15th October
Saturday started with clear skies and decent transparency, with the large active region(s?) of late heading over the limb it was a good opportunity to check out for CaK proms, and there were plenty!

Ha Full Disk 1st October
The sun gets ever lower in the sky but clear skies meant I managed a quick full disk in the afternoon. I was keen to try out my new Beloptik ITF filter on the BF15, and are pleased to find it has higher transmission, with exposure time of 5ms compared to the usual 6ms. The disk was taken with the double stacked 50mm setup, 2x cemax barlow and the ZWO183mm camera.
