Moon filter

Postby Sophiecentaur » Sun May 15, 2016 11:15 pm

I have been looking at some lovely views of the Moon with my new Baader Hyperion Zoom (which I am really pleased with and would recommend to anyone who wants a set of good 8 - 24 mm EPs) The step change in quality from the 'kit' EPs that come with the 8" Dobson is really significant and I get the feeling that I would have to pay an awful lot more for significantly better performance.
Any road up, it seems that I would get even better views if I use a Moon Filter. The question is which one? The magic 13% seems to crop up in the adverts. Is the 1/8th brightness particularly relevant for Moon watching? Also there are various other types of filter on offer. It would be very helpful to get some feedback with personal views of what and why in this matter.
Would £20 get me something worth having?
Cheers in advance.

I have a very cheap moon filter that came free with something and it's well worth using, as the moon can be eye watering bright otherwise.
As for what'll work best for you, it's very hard to say.
You could try asking at a local astronomy society. You may be able to borrow a couple to try out.
Scopes: Meade 8" SCT, Skywatcher 127mm Mak, Raffle winner of SW ST80
For imaging: Pentax K5, Asda webcam, Star Adventurer (new toy)
For companionship: Mid Cheshire Astronomical Group.

Just to add my two pen'orth! Some people I know like using a variable polorising filter. The brightness of the moon varies so much, and this little device allows you to adjust the brightness as desired.

Here is an example, but there are others and you may get them cheaper elsewhere.

I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

You can also use just one of the polarising filters from the pair to improve planetary viewing.

I 2nd this VERY strongly. It is also very useful for viewing Venus and, sometimes, Jupiter.
How can I be one with the universe when we don't know what 96% of it is.
