  • Identical filter thickness to existing standards, with utmost care for parfocality
  • Blackened edges all around, with filter-lead-side-indicator in the form of a black frontside outer rim, to additionally eliminate any reflection due to light falling onto the edge of a filter
  • Each filter coated individually, with sealed coating edge (NOT cut out of a larger plate with coatings left exposed)

Life-Coat™ coatings resist moisture, temperature extremes, and are hardened to withstand normal cleanings.

Baader Planetarium guarantees their Life-Coat™ coatings will not peel, flake or physically degrade and will withstand repeated cleaning with fine optical cleaning equipment. The Limited Lifetime Warranty applies to the original purchaser and does not cover failure from mis-use, physical damage through improper handling, or improper cleaning.

To make a warranty claim, simply contact your retailer where you purchased the filter with proof of purchase (commercial invoice) and a detailed failure description. The dealer will then advise of the next steps.

First impressions
Thursday, 16 September 2021  | 

My Ha and Oiii filters arrived yesterday and amazingly there was a break in the clouds last night to give them a try. Things were stacked against me. The seeing was poor, a 9.5 day old moon was less than 20 degrees away and my target M16, which was very low in the sky. So, when the first sub came in it was a wow moment for me. The level of detail on the Ha sub, I was very impressed with. I am in a Bortle 4 sky, but being early in the evening my neighbours had their security lights on, but the filter cut through all of that. Certainly on first impressions the best filters I have used, so will be interesting to see what others who have more experience than me make of them.
