The Moon is bright, this is basically a necessity. Much more comfortable viewing and better contrast.

So Glad I Bought This...
22 January 2021  | 

I have never viewed the moon through a scope before, low and behold it''s bright and fierce to my eyes when viewing without a filter. I am so glad I purchased this. It didn't affect the views i had at all and made viewing the moon so enjoyable both with a 25mm and 10mm eyepiece.

Astro Essentials ND Filters
08 December 2020  | 

I brought the set of 3 of these small but amazing filters. These are just as good as expensive rivals and if the moon is a tad too bright you can always add on another ND filter. The detail of the moon's surface is incredible with these filters - offering quite an immersive experience. I also found the atmospheric shimmer, particularly when the moon is in the mid-lower regions of the sky, somewhat lessened. Gone are the days of being temporarily blinded when moving from dark sky objects to the moon. Thanks a million FLO - your products and service rock.
