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_...

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...

Hi all,

It may take some time to load.

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.

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
Cheers,
Taratasy
