Askar M54 OAG (Off-Axis Guider) + Askar M54 Filter Drawer - Unboxing and Review

[@dalehollenbaugh6084]

Askar has updated their OAG aperture since this video was released. Instead of an 8.9mm round aperture, it now uses an 8.9mm x 8.9mm squarish aperture, which covers more of the IMX174 sensor. This change took place at least as far back as Oct. 2022.

Thanks. Does this work well for a Celestron 9.25 scope? I have an external Moonlite Focusing Flange attached to the tube. And I also have a 0.63x Meade reducer. Would there be any issues in focusing? My guiding camera is ASI 174mm.

Thanks for the video. How far down can the stalk go toward the optical axis?

I'm not quite sure. I have the OAG mounted now, so I can't measure it. I can say that I didn't have it all the way in on my APS-C sensor, so if you have a smaller sensor than that it could go in further and get closer to center.
