I plan to take a shot at Neowise 7/10/20. My scope will be an Astro-tech AT66ED 66 mm F6 and my camera is an ASI224mc. This is the first time using the 224mc. I have used my 174mm to capture solar. Can anyone give me an idea on settings for capture and gain? How long for exposures? I will be using SharpCap.

400mm is WAYYYYyyy TOOOoooo long, and the 224 WAYYYyyyyy, WAYYYYYYY, too small.......The Comet is 12X the size of the moon

A 135-150mm camera lens on an APS-c sensor is working good for me, if all you want is comet and it's full tail..

If you want some foreground, you need 105mm or less

How about a 103 mm f7.7 and 224mc? Or a 174mm? I'm new at comets. I meant a 66mm in the original post.

You're not going to get anything with the 224.......besides an extreme closeup of the nucleus.....

The Comet is HUGE......more than 12X the size of the moon.

Do you have 10mm fl camera lens you can use ?

If you have a regular photography camera and a tripod, you can get a wide field image. I got Neowise that way. If the camera has manual settings, and not a point and shoot, ISO 400, about 3 seconds, and f stop almost completely open, experiment with f stops. Better than nothing.
