filter wheel and filters

[cbbella]

hi, i have a qhy163m camera and i'm about to buy a filter wheel from aliexpress.  could anyone advise me on the differences between these two please.

this one is £207 for the QHYCFW3s-SR 1.25x7 or the QHYCFW3-S-US 7x1.25  QHYCFW3M SR QHYCFW3M US Inch 36 Mm X 7 Ps Elektrische Filter Wiel Elektrische Telescoop Filter Wiel|Monocular/Binoculars| - AliExpress

and this one is £175 for the 7 Position 1.25inch   QHYCFW3 S 36mm 6 ps 1.25inch 7ps electric filter wheel electric telescope filter wheel|Monocular/Binoculars| - AliExpress

i'll be using it on a skywatcher 200p F5 ota.

as for filters i was thinking a Ha filter and also these as they're optimised for the asi1600 which i think has the same sensor as the qhy163m.  https://www.firstlightoptics.com/rgb-filters-filter-sets/zwo-125-lrgb-filter-set-optimised-for-asi1600.html

what are your thoughts please

I'm afraid I can't help with the specific question but you might get more luck posting in one of the main imaging forums here as this one is mainly for EEVA equipment and not so many people appear to use filter wheels for EEVA.
