I recently purchased a preowned Sky-Watcher StarTravel120 OTA (120mm chromatic refractor, f/5) and trying to figure out what is the best configuration for planetary viewing.
I know this scope is not the best tool for planet viewing but still enjoy taking it out to my back yard once in a while...
This week I had some clear skies and managed to view both Saturn and Jupiter. Since this is a short FL scope, using a 6mm EP (Zhumell Z series) I can only get a magnification of x100 and the visible object is very small
I don't have any decent EP below 6mm but tried some cheap Sky-Watcher 3.6mm MA EP that I've got with the scope but the visible image of Jupiter/Saturn is still very small. I also tried using a 6mm Or. with a Barlow but the image was quite bad...
I already ordered a new dielectric diagonal (a SvBony clone form AliExpress) and now I consider buying a higher power EP.
What about a 2.5mm TMB? How will it work with my scope? Will it produce a "big enough" image of the planets?
Any suggestion about how to get better images from this scope?
