Re: ASI ZWO 1600MM vs ASI ZWO 1600MM Pro

The "classic" for solar imaging is the ASI174MM. It supports 1936X1216@164FPS Full well: 32ke- It is a global shutter camera. The 1600 supports "only" 1920×1680 57.7fps Full well: 20ke- It is a rolling shutter camera. But the 1600 has about twice less read noise which is a + factor. From the numbers...

Re: April 8 Observations and new Altair wedge!

A solar wedge gives much better/contrasted view(image) than a regular front astrosolar (or any other make) filter. The solar continuum filter is passing above 800nm, at least mine. I would strongly recommend to use an IR cut or an UV/IR. The polarizing filters are also generally passing in IR. Care ...

Re: Double stack Coronado SM

Very interesting this idea of having the SM60 almost "inside" of the SM90. The SM90 has probably a bigger central spot than the one of the SM60. Here is my experience about stacking 2 old fashion SM60. Stupidly, the treat of the front and rear of the SM are not the same, so an adapter is needed. Tun...

Re: 12" White light Newtonian

"Don't forget to de-aluminise the secondary mirror!"

If you do so, you will have a very strong filtering.
Maybe you want it that way, but keep in mind that you will have to collimate it!
