The camera is JAI BM-500GE, a B/W camera which can capture 5MP@15fps.

I have extra one for sale, price US980.

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:

Merlin66, I have been waiting for Surplus Shed slit for several months... I will try the blades with magnet later. The collimation for this toy is not so easy, the sharpness of the spectrum lines are not good and not even, I think I will try to use laser light to help collimation later. Can you send...

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

Thank you all, I was following the design of VHIRSS:

Is this slit better than a homemade one? In which way? Thanks!

I can find the filters have been relisted now!

Is there anyone know the price of repairing a decontacted etalon?
Or is there anyone here can provide recontacting etalon service? B) B)

It seems the 0.1nm filter pair is sold out, will there be more in the future?

May I know if a blocking filter is neceasary after using this Omega filter pair?

Is this spectrohelioscpoe under construction?
Is the size small and light enough for most equatorial mount?

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:

Thank you all for your welcome!
I'm planning to mod my PST and will need your help in the future.
