SW Evoguide 50 Vs Samyang 135mm

[Mr niall]

Hello there. I'd really like to replace my truly terrible Canon 70-300mm. I know the weapon of choice for "not quite widefield" focal lengths seems to be the Samyang 135mm but they're not cheap (well they are cheap, really cheap for the quality but hopefully you get my drift) but the Evoguide is literally half the price. Literally literally (not quite literally)

Has anyone tried imaging with the SW Evoguide 50? Looks like it may be reasonable even if 240mm is perhaps a tad over what I would choose. The only risk is that I have absolutely no use for a guidescope so it may be an expensive mistake if I get it and it's terrible!

I just want a bit more reach than my Canon 18-55 kit lens which, in all fairness, is a lovely lens.

The evoguide is not corrected, so you'll get distortions on anything but the smallest of sensors.

Have tried it for fun, but it was only sharp in the very centre of the aps-c sensor, below examples are heavily cropped.
