Mars through a 4" refractor at 125X

I took a look at Mars this weekend through my C102 and was very
delighted with the view. I was using an 8mm Radian about 125X. Though
the image was a little dark (my small aperture) after a few minutes I
was able to see a lot of detail on the planet along with the polar ice cap.

That's great Bruce! Try to increase the magnification to 150x - 200x
and use a #21 or #23 filter. You maybe surprised at what the C102
can do.

talking about filters: what filters (for Mars observations) can/should I use
with a ETX105?

Well, I would try those that won't cut down the transmission too much.
I have great success with #21, #23 (now that Mars is soooo bright)
and #80A filter (I think I need a #38 now that Mars is soooo bright too).

For general Mars work:
My current favorite is a variable polarizing filter (used with a 5"
telescope). A former favorite was a #23A light red filter. An orange
filter would also be worth considering for that size telescope.

Other filters can be beneficial for certain specific features; but the
above is IMO a good 'short list' of the best overall Mars filters for
use with small to medium aperture telescopes.
