To see a decent amount of detail on Jupiter you need to be around 150x to 180x magnification. Mars is a much smaller object and is very close to the moon so it will be washed out with light a fair bit.

To work out your magnification dived the scope focal length by the eyepiece size to see what you're getting. :)

with the 15mm you'll be getting 43x I think, with the barlow, double that, so 86, you probably want a bit more and as Kim said, moon at the moment will wash a lot of it out on planets

An f-5 scope ain't so forgiving on the lower quality eyepieces and barlows. A good barlow like the Tal 2x would probably help a lot with your 8mm eyepiece. See if you can borrow one at a meeting to try it out and see what you think :)

(You'd get 162x magnification with the Tal and 8mm)

Ok - but beware the seeing - it'll need to be good - don't forget when you magnify an object you also magnify atmospheric imperfections.

You want a clear sky with good transparency - the scope must be cooled for half an hour first - ensure your eyes are dark adapted - check collimation is spot on (do a star test to check focus and collimation) - and keep your fingers crossed lol :)
