Sorry to say this but a 5" is too small to be much good for DSOs. In dark skies 7" or 8" aperture is where it gets interesting. In light polluted suburbia you should have kept the 10".

The alternative is to forget DSOs and consign yourself to being a lunar and planetry kind of guy. Maybe not a bad thing if you only get out occasionally.

By way of example at Blackheath recently under superb sky, we had a 130mm triplet APO, a 150mm mak and 180mm mak.

What was interesting is that the 180mm could show markarians chain quite nicely. In the 150 you saw the "eyes". In the 130... fuggedit.

The 180 was also just able to pull in lots of the mag 9-10 faint fuzzies around Leo, though these were all hopeless in the smaller scopes.
