Barlow + T Adapter,
Verified Purchase(What's this?)
This review is from: Celestron T Adapter/Barlow 1.25 Universal (Req. T-Ring) (Camera)
Excellent quality. Great for lunar/planetary work. An added bonus is that you can still attach an ocular or diagonal with the T-ring mounted, so focus is close switching between eyeball and camera!
Great price! I've paid more for a standard Barlow.
