Moon filter piece for Skymax 127

[osilvab]

Hello,

I did some observations of the moon previously but I felt the moonlight is too strong in full moon phase, specially for the kids. Then I bought a moon filter Crystalview 2" for my Skymax 127, but it seems it doesnt fit on the thread. Im not sure if I am missing something here or I just bought the wrong filter.'

any advice or suggestion in which filter to use?

 

Thanks

What was you trying to attach the filter to ? Normally the filter would be attached to the eyepiece using the thread in the nosepiece or possibly the diagonal. In both cases the thread size of the filter should match that of the eyepiece or diagonal in use (1.25" or 2")

I though it would be possible to attach it between the telescope and the diagonal. I think there it is 2".  the eyepieces are 1.25" right. so probably I need a 1.25" filter 😕

A simpler option would be to cover part of the telescope opening to reduce the amount of light coming in. Most scopes come with a lid which has an opening and cap, try that.

In my opinion the Moon filters are not worth it.

You don't need a Moon filter unless you think you need a Moon filter.  🙂 It is bright compared with the night sky and will dazzle you for looking at faint night sky objects, but in actuality is no brighter than a sunlit asphalt road.   Do not cover part of the aperture - that just converts your telescope into a smaller and less capable one.

ND0.9 is the standard filter for smallish scopes. Some find the glare of a bright moon startling and with dark adapted eyes it can be, but it's harmless. I find the ND0.9 helps with revealing faint shadow detail and doesn't reduce the resolution of the scope like an aperture stop does.

I've tried a couple of neutral density filters, a green "thing", and a couple of colored filters.  I find a yellow #8 to work best followed by a medium orange #21.  The others were marginal at best IME.

I think I read somewhere that some people use purple filters on the moon, but I've never tried that.  OTOH, Antares 1.25-in filters sell for about US$10 - US$12 each, so experimenting is not costly.  You can even stack them if you want.

Usually I observe around first and last quarters though, so I don't bother with a filter.
