The MegaMOAG takes the design of the MonsterMOAG and adapts it for telescope systems with larger optical openings. It comes with the same camera-s...

MOAG means Manual Off-Axis Guider. It allows you to guide your telescope to obtain sharp, round stars by guiding in front of your filters using unf...

What about NII and H-a?This is a bit complicated. It is not well known that most H-a filters pass both H-a and NII. H-a emits at 656.3 nm and NII e...

This Astrodon Near IR-Luminance filter blocks below 700nm and transmits at least 97% of light above 700nm all the way to the limit of the Si detect...

The next filter to complement your LRGBH-a set is an oxygen filter. OIII (“ohthree”) emits light near 500 nm and is a blue-green- or teal-colored f...
