Re: 3D printing and SHG

Thanks Ken,
I downloaded BASS. However I am working on a Mac, and the software cannot seem to run on my windows emulator. I will need to find a solution to have a windows partition on my mac to make it run.

Re: 3D printing and SHG

Hello all, Here is an update on my 3D printed spectroscope. It works very well! I just had to cover it with alluminium tape to prevent light leaking through the plastic body. Raw spectrum of a fluorescent lamp: you can see I have a "smile" problem, I don't really know how to avoid it. IMG_1341s - co...

Re: 3D printing and SHG

Just finished printing the body of the specrograph. The grating holder will stick out from the small hole on the top for rotation.

Re: 3D printing and SHG

Thanks Mark :) Highfnum, Most cities and universities now have a "maker space" where 3D printing machines can be used for very cheap or even for free sometime. Generally you have to first take a short course to learn the basics, then you can come anytime and print anything you want by yourself. That...

3D printing and SHG

Hi all, Quick question for SHG makers here: have you ever considered using a 3D printer for making a SHG? 3D printing would allow easy and rapid design of small parts such as holders for grating, slit or lenses. The material is also pretty strong and very light. For exemple I am currently making a s...

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 ...

I don't see any proms in CaK, are they uncommon?

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.

Thanks Alexandra :)
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

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, ...
