The Sun - 23rd Feb 2019

Foggy and cloudy this morning but then the cloudy parted and left us with a sunny afternoon. There were no spots in white light but some faculae on the limb. I also did some polar shots, looking for polar faculae but there was almost no activity at all. There was a nice plage area in Ca-K as well as...

Finding Scopes That Are Well Corrected For Ca-K Imaging

Simple question, when looking at potential new scopes is there a way to tell if it will be sufficiently well corrected for Ca-K imaging? My assumption is the only reliable way to tell is to try it, which is kind of limiting. Thinking of moving from my achro Skywatcher Evostar to something like an F/...

The Sun - 15th Feb

Another glorious sunny day here. AR12733 continues to rotate into view although it shows no sunspots at this time. Loads of prominence activity in both Ca-K and H Alpha. Seeing was not the best today but I made do :P Proms were pretty faint hence some are quite well stretched! 1.jpg 0.jpg 2.jpg 3.jp...

Re: The Sun - 14th Feb

Thanks Alexandra, Franco :bow2

How far north / south do faculae have to be to count as "Polar"? I wonder if the group in my image from yesterday qualify as they did seem to be at higher latitude than normal (bottom right of this image)

Feb 10th - A Bit of an experiment!

I've been considering a short focal length frac for a while, mostly to get full disk images quickly in poor conditions but also to be able to capture full disk surface and proms that I can overlay. A Bresser AR102xs popped up on ABS for a decent price a couple of weeks back so I went for it. It's fo...
