A TZ3 is on my shopping list too...
What the etalon you will use with this TZ3 ?
I will use it with my Quark (without the 4.3x telecentric) and also want to try it with my CaK setup.

Re: Any interest in this part? LS50C modkit

Does the 'unit' itself support the weight of the camera / eyepiece etc behind it, or, it the weight supported by the etalon housing Apollo?

Re: Experimenting calcium imaging with small refractors

I am curious to hear how the AP130 EDT works out because it has implications for my AP155 EDF. Bob, you have the f/8 I take it and not the f/8.3. The f/8.3 is the same lens as the AP155 but stopped down to 130. But even the f/8 is somewhat similar. George Hi George, Frederic has done optical report...
