[SuperG]

I'm having a hard time here trying to decide; they're both triplets. I'll only be doing DSO astro imaging and currently with a cooled IMX294 sensor.

On the one hand, the Esprit appears to be well made and apparently has a built in flattener. The 400mm FL does mean I'll be undersampling a little.

On the other hand, I don't see too many of these Saxons in the wild. But they are a rebranded Explore Scientific right? It's got more aperture and I have a 0.8x Orion reducer to use with it. So the focal length will be just south of 600mm. The build is unknown to me.

Any comments or suggestions?
