Hi All,

This Lumicon 2" Night Sky H-Alpha Filter is designed for black and white deep sky astrophotography. This filter is a long-pass filter with 50% transition from blocking to passing at around 640 nm. Transmittance is 90% or more for wavelengths above 650 nm. The Lumicon 2" Night Sky H-Alpha Filter can be used either as a severe adversary to light pollution, or for enhancing the contrast of emission nebulae as well as other night sky objects that are bright in the infrared. Threads into industry standard 2" Digital Imagers, 48mm Thread.

I bought this filter back in the 1980's for use with Kodak 2415 Tech Pan Film, ah those were the days... So the case shows it's age but the filter is still in great shape.

Asking $50.00 which includes shipping and PayPal fee.

Need a 48mm to 49mm step up ring for this filter? Add $5.00 and it's yours.

Clear Skies,



  • Condition Excellent
  • Location Brookfield WI
