Skywatcher ED100 & WO Reducer

[Dave Moulton]

Focal reducer info on the Skywatcher ED100 seems to be thin on the ground . So if there are any Skywatcher ED100 owners thinking about this then maybe this image will be of help.

The image is a single 10 minute exposure just as a test. 1 dark frame used as well. The image does have its problems vignetting is an issue but not that bad. Stars also not too bad as long as you could crop the image down a bit. Not much worse than in standard trim I think.The pic is full frame BTW

Scope…….Skywatcher ED100 Pro

Reducer….William Optics 0.8 Mk111

I did do the same test on my Skywatcher ED80 which surprisingly came out much worse. If anyone has managed to get this reducer working nicely with the ED80 I would be interested to see a picture of the results and info on spacing etc.

Cheers,
