Post X8-flare prominence animation

Hi all,
I made a short timelapse of the loop prominence emerging from the sunspot AR2673 soon after the flare, enjoy :)
It may take some time to load.

Re: Building a basic spectroheliograph

So, I played a while with the SHG spreadsheet and I found out a good design for my new SHG. It will have a classical design using camera lens, greatly inspired by Chagnard's work. The different parts are: Telescope: a 50mm f/10 lens, fited in a PVC tube Slit: the one from Surplus Shed Collimator: 20...

18 August prom animation

Hi all, Yesterday's solar prominence was very large so I made my first solar timelapse using my Lunt LS50THa and Zwo asi-120MMs camera :) I took 14 images every 5 minutes. It was a real pain to stack everything together :!: I wanted to take more image but clouds got in the way around noon. Anyway I ...

Re: Lunt LS50THa Full Disk

Thanks both of you.
The proms are clearer because on the first image I pushed the gain too high resulting in a lot of noise, so I was not able to use the wavelets in R6.
This time I put the gain at 10.

I just made another one today, I think it is better (less sharpining and better color). The prom on the upper right is very nice.

Lunt LS50THa Full Disk

Hi all,
Here is a full disk I made today with my Lunt LS50Tha and Zwo ASI 120mm-s camera.
The seeing was average.
I was trying to improve my false coloring and I think a found the RGB values that suit me! R: 3.2; G: 1.2; B: 0.3

The third one is very impressive! I am just wondering is that the photosphere at the limb?

Re: Building a basic spectroheliograph

Hi Merlin66, In your book, chapter 7 page 132, you write that the " Small Refractor Classical Spectrograph " would achieve " a dispersion of 0.15 Å/pixel, a resolution (at Hα −6563 Å) of 0.61 Å (R = 10800) and a wavelength coverage of 244 Å.

The Sun in a pinhole — solargraph

Hi all, Last March I made a solargraph i.e a very long exposure of the sun using a pinhole camera. I made my camera from a beer-can loaded with photographic paper, strapped it to an electric pylon facing south and let it there for about 3 months. You can see the path of the Sun getting higher and hi...

Re: Building a basic spectroheliograph

Hi Guys, It has been a long time! Since last time I completely stopped my SHG project because of a lack of time (end of holidays, had to go back to study) and lack of motivation, I must admit. Now, I still don't have much time, but I want to try again and build a new SHG (the old one was too wonky, ...

Re: Littrow SHG prototype

I had the same thing with the Zwo ASI 120mms.
The webcam worked perfectly well... It really seems it depend on the camera.

Is this effect related to newtons rings ?
