Agena Synta / Vixen Style Dovetail Mounting Base / Shoe for Finders - For SCT # SCTFURB
Nothing special, but . . .
It’s exactly like the one that came stock on my GSO Classical Cassegrain. I wanted to mount another one so I could have a RACI Finder in one and a red dot finder in the other.

APM 1.25" 6.25x Coma-Correcting ED Double Barlow # APM-Komakorr-DoubleBarlow
Versatile barlow
I have only used 2.7 so far. excellent optics and clear views are possible with this barlow. And a second one to boot if your telescope can handle it. I have yet to explore the true value of this barlow.

Celestron Star Pointer Pro Unity (1x) Finder # 51635
Nice pointer
Since there is no red dot in the middle of the finder's field of view, it is very convenient to use when star hopping to faint objects.

Explore Scientific 1.25" 5x Focal Extender / Barlow # FE05-125

This focal extender is somewhat smaller and lighter that I would have guessed for a 5x. I see no obvious problems with the light being passed through it. This extender is too powerful for my telescope (130 mm reflector) with most eyepieces, but is e...

This is a good buy
I haven't had this diagonal for very long but from what I can see from two nights of viewing the moon is that it shows a definite improvement in contrast. I'm using it with a 102 f6.5 refractor. The view looks better on the moon than the di...

Explore Scientific Finder Scope Reticle Illuminator # FNDRILLUM
Versatile Illuminator
I use this on the polar scope for my AstroTrac. Works very well. However, this and other similar makes have one fault. Their dimmer control needs work. That's usually the first thing that goes.
