Calcium Swathe 23rd January

Cak-crop-colour I tried out my new 127/1200 refractor yesterday for a bit of calcium, I thought stopping down to 60mm would be fine, but the seeing really was that bad, realistically I should have stuck to 40mm. My plan is to have range of scopes that will be stopped accordingly to match the sampling of the pixel size of the camera used, with the size of the scope matching what the seeing allows. I plan to use this scope and camera combination at 72mm which will give me f16 at the filter. I had to do a lot of psot processing to salvage this image, normally my calcium images are minimally processed. Even with dodging snow showers to image it is worth it!

AR12797 & AR12798 in Ha 23rd January

Ha-crop-colour Difficult to observe in the snow with passing snow showers, but I wanted to get out and take a look. Using the SM90 I struggled to get evenly on band without my laptop screen and this was my best effort. The filaments closer to the limb highlight the solar jet stream of magnetic activity associated with cycle 25.

CaK Full Disk 22nd January

CaK-FD-colour The weather went from total clear skies to cloudy unexpectedly today over about 20 minutes. Fortunately I was able to grab a quick Cak disk with the 60mm f16 setup before the clouds sealed the sky. Its nice to see the sun getting steadily higher in the sky and also the new active region that has formed in the northern hemisphere over the past 24 hours. Something is also about to round in the northern hemisphere over the eastern limb. Looks like theres things to look at in the days ahead if the weather obliges, fingers crossed!

AR12796 in Ha - 16th January

ar12796-colour There was just enough time to run off just over 1000 frames for this image before the cloud rolled in. I did manage to get the filter tuned properly, but wasn't enough time to get rid of the dust bunnies off the chip. The new active region looks nice as do the filaments.

Ha Full Disk 16th JAnuary

HA-FD-DS-colour The sun came out briefly, very briefly, on Saturday lunchtime. I managed a full disk but didn't get time to tune it properly. Nice to get an overview though!
