174 or 432
new camera.
a zwo 174 or better a 432 is still worth it. what do you recommend to have speed and sampling around f30 in Ha

Re: 174 or 432
I would go with the one that has the highest QE in Ha. From there adapt sampling with a reducer if necessary.

Re: 174 or 432
It has a chip diagonale of 28mm, the quark has a free aperture of around 20mm. So even without reducer you will get heavy vignetting with this camera.TareqPhoto wrote: ↑Thu Oct 26, 2023 9:54 amIMX571 sensor camera.

Re: 174 or 432
You can use a camera with either a small chip like the imx462 or a camera with large pixels.

Re: 174 or 432
I don't have 462 but i really really wish or want to sell my 290 first then i can buy that 462 [mono] immediately, and about large pixel something like what? I have 174 and 432.

Re: 174 or 432
The 290 you can use with the daystar reducer. The 432 you can use too, its basically just right for the quark. No reducer needed in this case.TareqPhoto wrote: ↑Thu Oct 26, 2023 4:55 pmI don't have 462 but i really really wish or want to sell my 290 first then i can buy that 462 [mono] immediately, and about large pixel something like what?
