Deddly Posted July 2, 2023 Share Posted July 2, 2023 Is it a filter for taking photos of the sun through a telescopic lens? Quote Link to comment Share on other sites More sharing options...
AlamoVampire Posted July 2, 2023 Author Share Posted July 2, 2023 Nope, not a solar filter. Its filtering for something very specific. Here is M31 taken using a similar filter i found on the internet 175907022023 Quote Link to comment Share on other sites More sharing options...

AlamoVampire Posted July 6, 2023 Author Share Posted July 6, 2023 (edited) @Deddly it is a clip in Hydrogen Alpha filter for canon eos cameras. The particular wavelength of Hydrogen Alpha its letting pass into the camera is 12nm for this particular filter. Hydrogen Alpha can be filtered to other wavelengths, but this one in particular is 12nm or nanometer. Its used in deep sky astrophotography. 093907062023 094107062023 Edited July 6, 2023 by AlamoVampire Quote Link to comment Share on other sites More sharing options...

Scarecrow71 Posted July 7, 2023 Share Posted July 7, 2023 It looks similar to an Edison bulb, but that is not correct. Definitely some kind of tube. Probably related to light or sound. Quote Link to comment Share on other sites More sharing options...
AlamoVampire Posted July 7, 2023 Author Share Posted July 7, 2023 Edison bulb? No. Tube of some kind? Yes. But what kind? 195307062023 Quote Link to comment Share on other sites More sharing options...
AlamoVampire Posted August 8, 2023 Author Share Posted August 8, 2023 Ok since its been a month and no one else has guessed. Its a radio vacuum tube for an older radio. @Scarecrow71 since you were closest I think you earned the honor of next picture. 023008082023 Quote Link to comment Share on other sites More sharing options...

Deddly Posted September 15, 2023 Share Posted September 15, 2023 (edited) Antarctica would have sufficed, but I guess you looked at the file name. @AlamoVampire wins with an amazingly fortunate wild guess.
