Lumicon Comet 2"
Recensione di D. P. su 11.05.2022 14:28:03( 3 / 5 )
I bought this filter a few months ago on this site. Unfortunately I haven't been able to use it yet, as comets are not often seen. But I am really disappointed with the real transmission of the purchased filter, as each Lumicon filter (Farpoint Astro) is accompanied by a transmission / reflectance certificate; and the one shown by the site, reaches 97% from 505-510nm, while on my certificate, I indicated at 501nm 82.31%, 511nm 86.92%, and 514nm 84.20%, so far from the data provided by the diagram demonstrative, much less performing. And of course, I didn't want to buy a second choice filter, also considering how much I paid, and therefore, I don't understand, why there is so much difference.
