Uranus F29 and some moons at F4.5

SPX350 F29, EQ6, Flea3, Astrodon filters.

As Uranus is nearby I though I would nip across and take a quick look seeing was 6/10 - time 11.30UT - 30.10.10.

Sensitivity of F3 clearly better than DMK, some breezy movement so had to use 17fps. No disc detail but I did not really expect any, never image uranus at this length before.

The night before I also had a go at F4.5 with 3fps to see if I could see 14th mag moons and I could so don't need long exposure as with the DMK because of the F3's increased sensitivity. Not sure which are the moons but I think I have 3 of them - time 11.53UT.

Regards, John.
