Continuing tests of the new SVbony SV535 "One-and-a-Half"
The filter is in the drawer in front of the objective lens. It seems a filter for "fast" telescopes is needed here. Only, it costs more than the telescope itself.

L-extreme or similar. Or an analog from Antlia or Askar.

So they will cost more than the telescope itself, whether it's the L-extreme, the Antlia ALP-T Dual Band 5nm Ha&OIII Highspeed, or the Askar ColourMagic... But there is the L-eNhance. And with it, in just over an hour, here’s what I managed to capture: https://deepskyhosting.com/5TiUNIg
