December Solar Challenge
Post an image/sketch of a tree prominence you find on this Sun this December. We all know some proms are called hedgerow or tree proms as they appear to look very much like one. These are quiescent prominences.
For a bit of fun, the one that looks most like a Christmas tree can be SPOD on Christmas day
Let's see all these December trees and hedgerows

Re: December Solar Challenge
Here's my effort. Not sure that it's a tree though.

It's getting more and more difficult at this time of year in the north. Really quite unstable air and less well defined details with the extra air we're having to image through. Anyhow, some Sun is better than none

I was wondering about CaK imaging ? I saw info on the Baader Ca K line filter (1.25 inch filter) on the Baader website. Did not know how that would work with a normal white light set up (I only have Baader solar filters on the front end of a refractor), and no other filters. I dont have a solar wedge or continuum filters yet.
Is the Ca K line filter (looks just like a small filter with threads) about 1.25 inches diameter enough or do you need the full Daystar Ca K module costing over 1000 USD or GBP ? However, I then see Daystar has a Ca H module ? so are they looking at different lines ?
Badder K-line is about 279 GBP for the 2 inch version (less for 1.25 inch) and Daystar Ca H module is about 1070 GBP (+ you need other stuff and ERF)..

Re: December Solar Challenge
Hi Magnus,
I guess this should be discussed on the ‘this is Solarchat’ pages, but to provide a comment here, I would say you get what you pay for and the cheaper Baader filter option will not give a satisfactory result, assuming you’re interested in capturing chromospheric network details. The bandwidth of the Baader K-line is simply not narrow enough. I use a Lunt CaK module with an additional narrowband filter to tighten up the band pass.
You may have just sparked a debate as there are other favourable solutions.
Alexandra/Mark, please can this be moved to the main section?
Cheers
Stu.

Thanks for your input. I realised this Ca K imaging is too advanced for me at present. I have to do a lot of work in my day time job for the winter months, so will not be able to digest much, so apologies for taking up your time.

Re: December Solar Challenge
Hi:
Here is my X´mas tree looking version of a protuberance.
Thanks for looking, it was taken with a 102mm f/7 Stellarvue working at f/28 with a Baader 4X telecentric plus an old Daystar T-Scanner 0.45A° Ha filter.
Regards,
Eric.

It looks like you did not water the tree.
Best regards, here I put another tree, hope it does not fall over.

Re: December Solar Challenge
I'm back after about three weeks of renovating our house.
So much cloud in this period that it is impossible for me to see the sun...
I hope you see a kind of a tree in the older image, that's not a December sun.
