Baader Semi-APO Filter - 1.25" # FSAPO-1 2458398
Very nice to sharpen an achromatic refractor.
At the cost of dimming the image a little bit, it cuts down chromatic aberrations without too much impact on color balance. It also removes some light pollution (as long as your town still uses sodium lights). It certainly increase the usability of m...

Optolong City Light Supression / Light Pollution Reduction CLS Filter - 1.25"
Very Impressed.
This CLS filter fit perfectly into my unmodified Canon 5D Mark ii . I just set my camera for mirror lock up, pressed the shutter release to lock up the mirror and then just popped in the filter. I’ve tested the filter and am very pleased with the r...

Baader Premium Eyepiece Filter: Yellow, 495nm Longpass - 1.25" # FCFY-1 2458301
495 Longpass Filter
I have two small fast achromatic refractors and this filter eliminates the purple fringing on bright objects helping me to see more detail. It does produce a strong yellow coloring to everything viewed, much more so than a #8 light yellow filter, but...

GSO 1.25" Color / Planetary Filter - #82A Light Blue
Planetary filter
I brought the filter in hopes it would enhance the spiral structures around galaxies. It worked especially well on M51 where the spiral arms were enhanced.

Celestron 1.25" Moon Filter # 94119-A
Not what I expected
The moon filter I got was a black plastic material (rather than metal or aluminum) with grooves that didn't thread into my eyepiece.

Coronado 1.25" Secondary Blocking Filter for SolarMax - 10mm # BF10
Extremely expensive
I does the job. This is a basic 1.25" mirror diagonal (that would cost $50) with an ITF (the maier photonics equivalent would cost $75 and the BelOptik equivalent about $200) and the blocking filter itself. This mens that we are paying about $35...

Baader Premium Eyepiece Filter: Yellow, 495nm Longpass - 1.25" # FCFY-1 2458301
Sucks
Did absolutely nothing for my achromatic refractor. I had to pay for shipping it back and return S&H charge.

GSO 1.25" Color / Planetary Filter - #29 Dark Red

This filter when combined with an IR/UV filter can be the first step toeard trying Ha imaging. The band width will be very wide but the combo is an inexpensive way try this segment of nebula imaging. I have numerous GSO products and have been satisfi...

BST 2" Variable Transmission Polarizing Filter

I like that this filter can be disassembled into two segments and installed in front of my diagonal and the bottom of my eyepiece. Rotation of the eyepiece gives you the ability to optimize the polarizing effect on a bright target such as the full mo...

Celestron Oxygen III Narrowband Telescope Filter - 1.25" # 93623
Great Views
I purchased this filter to get better views of Nebula. The filter definitely highlights the contrast of the nebula against the darker background. The threaded filter fits all my 2" eye pieces and is a nice addition to my observing tools.

Baader Semi-APO Filter - 1.25" # FSAPO-1 2458398
Excellent product - It works as advertised
Read the "Semi APO" claims and bought one expecting to quickly return it for non-performance. Tried it in my Bresser AR 127L / 1200 attached to the 2" diagonal, focused on the moon, very bright stars and in daytime on a Birch tree down...

Baader Premium Eyepiece Filter: Yellow, 495nm Longpass - 1.25" # FCFY-1 2458301
Solid Chromatic Aberration Removal
Following the advise of experienced owners of fast acromats, there was a higher preference towards the 495LP over the Fringe Killer to remove CA. I have done basic tests and found the CA to be under control in my G'n'G SW120ST. Star fields ...

Great but
Negative point: As the product is shielded and I do not have technical assistance in my country, I would like electrical connection to be stronger. It seems a fragile.
