Meade Series 4000 #3200 Lunar And Planetary Color Filter Set # 07544
Agena telescope filter set
Good quality with metal bezels (not plastic) and very economical. Easy on & off from all 1.25mm eyepieces. Agena delivered them promptly. The filters enhanced my planetary and stellar viewing. I highly recommend them.

BST 2" Variable Transmission Polarizing Filter
A must for viewing the moon
This made viewing the moon a much more pleasant experience. The variable filter makes it convenient for both full and less-than full moon viewing. I am no longer nearly blinded after viewing, and they didn’t seeem to affect contrast.

Baader UV-IR-CUT Filter - 1.25" # FUVIR-1 2459207A
UV/IR-Cut/L filter
It fits the need that I have for solar imaging/viewing. Highest quality. I like that the filter cases attach together.

Optolong IR Pass (685nm) Filter - 1.25"
Great filter for IR imaging
Very good filter at a reasonable price. Images taken with it are sharp and detailed, no distortions. Filter threads on my cameras and other accessories well, not sloppy, not too tight. I place it on par with my Baader and other high quality filters.

ZWO 1.25" IR Cut Filter # IRCUT1
Dark sky color correction
I was advised by zwo to use this filter to balance the extra green (rggb) found in the cmos sensor of the new and wonderful asi294mv pro camera. This filter worked as expected. The color out of the camera was beautiful.

Baader Premium Eyepiece Filter: Set of 6 Color Filters - 1.25" # FCFS-1 2458300
Best Color Filters I Have Ever Used
So far, I have used the light blue and dark blue filters on Jupiter and Venus with greater success than any other filters I have used. The green one works well on the Moon, especially when it is near full. I expect the orange to work well on Mars, bu...

Useful Mars Filter
Just received this Brandon filter and very pleased to see the quality workmanship that's gone into it. Looking forward to seeing the results as visibility of the 'Red Planet' increases.

BST 2" Variable Transmission Polarizing Filter
Powerful and Flexible Visual Tool
I particularly like separating the two polarizing layers, and threading one in the diagonal and one in the 2" EP. This makes adjustment of the polarization as simple as rotating the EP. Particularly useful for lunar viewing.
