SW Quattro 8" f/4 Impressive on Jupiter
Posted 23 November 2013 - 10:30 PM
The night was coldish (-4º C) and I left the OTA out for about 2 hours before viewing; I didn't use a fan for cooling.
With Jupiter high in the sky at about 2:00 a.m., the view with the 6mm Delos (153x) was very nice, and with the 5mm Nagler T6 (184x) also nice - nice bands, with irregularities/ festoons, and the Great Red Spot.
The view was significantly more pleasant than with the Skywatcher 120ED 900mm f/7.5 refractor, although, to be fair, the refractor didn't have as good a mount (an AZ4 on the 120ED vs iOptron iEQ45 for the Quattro.)
Still, in the battle of the Skywatchers, I'll choose the 200mm Newt over the 120ED. It seems that aperture rules, despite central obstruction and fast optics. The Quattro seems to have done the optics well.

It would also be nice to compare with a C8 - I no longer have one, but I'm confident it would compare well.

It would be nice to compare the performance with a Mewlon!
Did someone once say, "so many telescopes, so little money?"
Get yee to some star parties and hopefully encounter a Mewlon for comparison.
As for Skywatcher, they seem to have good quality in all their product line. Kudos to them.
