LRGB filters (1.25")

Recommended Posts

I'm in the market for 1.25" filters, mainly for planetary. Does anyone have experience with budget-priced products from ZWO, SVBONY, TS-Optics etc.? The next tier seems to be Omegon, Baader, etc. I also noted Celestron filters at £275 on Amazon.  I'll be using a ZWO camera. Would it be better to buy the same brand?

SVBONY seem to have very high transmission (https://www.svbony.com/lrgb-filter#F9170A) according to the chart.

Here are some pictures of mine. I’m using them with a widefield setup of QHY9 and Nikon 180mm lens. So far I’ve just used luminance (and a baader Ha filter also in the wheel).

Thanks for the pics. Can their transmission levels really be that high?

Cannot speak for ZWO but the LRGB CCD set from Baader is superb.  They are 95% as good as the Astrodon ones at half the cost.  I highly recommend them.

The L filter has UV/IR cut and this is important when imaging with refractors to prevent star bloat.  By way of contrast the Astrodon L filter is very permissive I feel, too much so.

If you have the ZWO filter wheel then check the physical prominence of the filters in the wheel, too often the issue is that they stick out too much and jar the wheel.

I have a seven filter set of LRGBHaOIIISII ZWOs. I'm happy with them, but don't have a compare with anything else.

Those look very much like QHY filters
