The Moon and the Effect of Focal Length
Ever curious what the effect is of Focal Length. Attached photo shows the moon with different focal length. Background picture shows the moon with focal length 3000mm, the smaller ones 400mm and 200mm. All pictures taken with Nikon D60.
Celestron Travel Scope D70
This evening tried my new Celestron Travel Scope D70/400.
The moon was the target. Installing the Travel Scope is easy. I used my camera tripod instead of the Celostrons tripod as I already want to take some pictures. The view is sharp and since it's very light easy to handle.
Installing the Nikon D60 on the oculair is easy but limits the scope to handle easily as it become more heavy. Make sure the scope is rigour mounted and the tripod secured with some weight.
The Nikon D60 was connected using T-connector and the focal was enlarged with 5cm tube to have the moon sharp in the field. It's not needed to use a barlow 2x as the moon will not be in the focus.

Open sky... no comet Panstarrs
This evening open sky with low hanging clouds above the horizon. The moon above western horizon. But no comet Panstarrs visible with the naked eye. Picture taken at 7h30 PM. Or looking at the wrong place or comet hidden behind clouds. Next time more luck needed.
