I have a 294MC-Pro that I bought in 2018, and I have an issue with the red channel with very narrow band filters. From what I understand, it is a coating issue with the glass in front. Would purchasing this fix that issue? I would love to use this for duo narrow-band imaging again but it is really hard to get a good image with a restrictive filter like an L-Extreme.

Ho una 294 MC Color Pro, e dopo tante indaginj ho notato che il vetro protettivo non è perfettamente limpido e vorrei cambiarlo.
Ho un rifrattore e leggendo in giro vedo che consigliano un ir-cut per i rifrattori.

Se ce una scelta tra un AR e un UV/IR-Cut. Grazie

Should the protective window for the ASI294 be installed pointing in a specific direction, or is the anti-reflection both ways? Can this contribute to halos around bright stars?

Thanks

It is used to protect sensor. AR or UV/IR cut depends on your photograph need, both were OK.

David Churchill – :
As a follow up to my earlier post/question. I have added a IR/UV cut window to my ASI183MC. I purchased a 31mm Optolong filter. It’s the same thickness as the AR window and seats nicely on the existing O-Ring. I added a 0.5mm filler around the edge to keep the filter centered…. works great!! I just wanted to pass this along incase anyone else has a similar need.

Hallo, ich habe die ASI178MM und habe eine Frage zum AR Schutzfenster. Mein UV- Venusfilter hat ein IR-Leck und erzeugt schwache Geisterbilder . Ich habe das AR Schutzglas von der Kamera entfernt möchte wissen ob es besser ist das Glas wieder vor den Sensor zu setzen oder stattdessen einen reinen IR-cut Filter zu kaufen.

You can replace it with IR cut if you want.

Where can I find instructions on how to remove the protective window? I read the instructions on how to clean the sensor and window but it does not mention there how to remove the window itself. I haven’t received my camera yet so it could be a simple step but in case it is not can someone point me in the right direction?

Does it matter which way around the glass is placed over the sensor? I took mine out of my 120MM for cleaning and lost track of which side faced the sensor.
