Images of the Sun, our local star, at a range of wavelengths with specialist solar telescopes. Imaging tutorials, solar bits and pieces for sale, talks and outreach with the Charlie Bates Solar Astronomy Project CBSAP.
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.
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!
Monday was nice and sunny, I managed to get a trio of full disks. The sun is nice and active at the moment...
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.
Finally the opportunity to do some solar observing! The autumn sun is starting to get low now. Images taken with various setups.
