Re: 201305124 LS80T Sun

It seems the forum has changed the above image to a larger size with less details version.
This is a lower res. but more sharpening version, hope you like it:

Re: My newly DIY spectroscope and first light

I don't know how to make a good metal slit, so I just use a piece of paper to make a temp slit.
I think I will find a metal one and replace current slit.

I got a 30mm x 30mm grating from a China surplus shop and don't have its detail spec, I guess around 600g/mm

Contacting 2 pieces of glass (video)

You much see this video if you are trying to recontact your etalon.
The 2 pieces of glass stick together automatically!

Re: 20120429 C8 White Light Sun with ASI130MM

Thank you Merlin, I think the most difficult part for me to do the mod is to find a cheap large (>150mm) ERF / red filter.
It would be great if you can point me the right direction :woohoo: :woohoo: :woohoo:
