Continuing the testing of the The Mounty UK-1411DF mount (Made In The Mlya). And the SVbony SV535 105mm f/2.8 APO telescope. This time with a sulfur and hydrogen-beta filter. Here, both sulfur and hydrogen-beta are present. Objects need to be chosen more carefully for this filter, but the result looks more interesting than "all red" with hydrogen-alpha.

Continuing the tests of the new "half-frame" SVbony SV535, combined with testing the new mount The Mount UCH-1411DF and selecting a "standard" filter for this setup. So far, the favorite among filters is the Antlia ALP-T Ha + OIII 5nm in the "regular" version, for optics "slower" than f/3.6. Because it is available. And oxygen, albeit slightly, does show.
