Asi 1600 cool + newton 200mm

stijn_walbers

Hi to all,

Me name is Stijn from Belgium.

Is there anybody who has a zwo Asi 1600mm cool in combination with a 200mm f5 newton telescope.

My questions are: do I need a coma corrector, do I need a distance ring, do I need a flattener,...

In which configuration worked the camera as he should work.

Best regards,

Stijn

Hi Stijn,

I use a ZWO ASI1600mm-C with a 254mm F4.9 newtonian telescope and it does require a coma corrector. I'm using the GSO coma corrector with all of the ZWO supplied spacers plus one 15mm spacer to achive the 55mm spacing between the sensor and the coma corrector.

Yes, Always need coma corrector and distance ring

Hi Stijn,

Hello, Ghswen.

I have the same camera as you and I was thinking about buying myself a newton of 254mm....

My doubt is that, according to the formula

Sensor resolution (arc sg) = microns / focal length x 206,265

3.8um/1200X206.265=0.65

I understand that if the sensor resolution is less than 1, the image is blurred due to over sampling....

Anyway, I'd like to know your experience with that focal length and that camera or, if possible, any photos you've taken with that combination.

Thank you in advance. (And sorry for my English)

Carlos.

you can bin2 with the camera

so this won't have problem
