Moon filters

Since the filters for telescopes are just color gelatine on glass, what do i do for my camera lens? can i just use the standard color contrast filters for black and white photos, or do i need something more?

I guess they make telescope filters that way because they don't get a lot of rough handling like camera lens filters? A viewing filter is probably not going to work right for B&W photography.

Beware of color filters that are also not for B&W. Some of them look like they're B&W filters, but they're designed for color correction, and won't necessarily give you the added contrast of B&W filters.

Moon filters are just neutral density filters. So you want an ND filter for your camera. You can also use a variable polarizer as a variable ND filter if you want. Planetary filters are just single colors, so again that's easy. But other telescope filters can be way more complex, for example a typical deep sky filter will have 2 notches for oxygen and one for hydrogen. Buying a camera-sized version of one of them will make your eyes water.

When shooting the moon, isn't the problem that it is moving across the sky at a remarkable rate such that the sort of increase in exposure from a ND filter is liable to give the moon that elongated oval look?

Moon filters are largely for eye comfort with visual astronomy. They're not used as much for photographic astronomy since you can control light at the shutter. So there's no link between filters and tracking in any meaningful sense. You can get telescope-sized and camera-sized Equatorial mounts quite cheaply.

My issue is the glow on the moon. It really shows up on the paper when il get the enlarger going and im not sure if im actually focused or not.. and it looks funny on the finished print.

Can you show us all an example?

Thanks
