Hello All

I was asked for some suggestions of possible filters to improve observation of Mars for a refractor and the only two that sprang to my mind was a good orange 21# filter and maybe a LPR like the Baader Moon & Skyglow or the Astronomik CLS.

However, it got me thinking so I would welcome suggestions from anyone else if they have some other ideas.

Additionally, I would be very interested to know if anyone has tried and can actually discern any difference between some of the high-end coloured filters (such as an Orange 21#) versus the budget brands for a third of the cost?

All suggestions and input would be warmly welcomed.
