Beautiful and tested with case!
The best sun filter I've ever tried!
The Sun appears both in its entirety and in close-up with a large amount of detail and clear vision, contrasted and superior even to the various Lunts and Daystars that I have had in the past years.
Single stack: brilliant protuberances and spicules! Double stack: everything and more!
Unfortunately I no longer use it so here it is ready to give you the most beautiful emotions!
Plus CeMAX 25mm Coronado eyepiece and original case.
VI: You don't need to go any further with the operture and don't settle for anything less!
PS: With Double Stack, i.e. with the combination of two integrated Etalon filters. This reduces the FWHM of the light in the H-Alpha line to less than 0.5 Ångström.
Without Double Stack this value would be less than 0.7 Ångström.
Price: 2700€ and shipping comprensive
