Hello Everyone grin.gif

 

I intend to get into solar observing and imaging and have decided on a Lunt 40mm, as well as a solarquest mount.

I am a lot less sure about the camera.

 

I was initially considering the asi 178mm because it seemed ideal for full disk shots. But reading about the grid pattern issues, which appear to be inherent to the sensor, I am not sure what else to look for.

Now I am looking at the asi 174 due to it seemingly being the most well regarded for solar h-alpha imaging, but it would undersample with a 400mm focal length. I would pobably need a barlow.

 

Would seeing become a concern when imaging with a 174mm and a 1.5x, 2x or 3x barlow? (this would be my first time using a dedicated astro camera, forgive me if this question sounds dumb)

Are there any other options I could consider that are less expensive than the asi 174 mm (120mm, 290mm)? I am not dead-set on full disk images, I could compromise on something that can't capture a full disk if it is likely to be issue free from NR and bayer matrix

 

Alternatively, how difficult is it to mitigate the issues that can appear on the 178mm?
