Celestron Regal M2 20-60x80 (52305) review

An ED-glass 20–60x80 angled spotting scope in a magnesium alloy body, with XLT coatings, dual focus, a rotating tripod collar, a 1.25 in astronomical eyepiece mount and a T-adapter ring.

The bottom line The one spotting scope here that crosses properly into astronomy, because its eyepiece comes out.

The fitting is what separates it

A standard 1.25 in eyepiece mount. Every other spotting scope on this shelf has its zoom eyepiece built in; this one accepts the whole astronomical range — a wide-field eyepiece for star clusters, a short one for the Moon, a nebula filter screwed into the barrel. That single decision turns a birding scope into a small telescope.

The glass and the body

ED objective glass to control colour fringing, XLT fully multi-coated surfaces, and a magnesium alloy housing that the maker describes as lighter than the usual aluminium. Those are three separate claims and each addresses a different problem: colour, transmission, weight.

Focusing and framing

Coarse and fine focus rings, a rotating tripod collar with detents so the eyepiece can be set where the observer is, and a sliding sunshade with a sighting line along it. The sighting line is the detail that stops a 20x scope being difficult to aim.

The blanks in the listing

Field of view, close focus and weight. For an instrument at this price those omissions are conspicuous, and this page states them rather than importing figures from elsewhere.

Availability

What it publishes, and what it withholds

Strengths

  • The 1.25 in eyepiece mount makes this the only scope here that takes astronomical eyepieces
  • A T-adapter ring is included, so a camera body attaches without another purchase
  • ED glass, a magnesium body and dual focus in one instrument

Compromises

  • Comfortably the most expensive scope in this group
  • No field of view, weight or close focus figure is published
  • The XLT coating is a proprietary name without a transmission figure

What observers ask about this one

What does the 1.25 in mount change?

Everything about its astronomical use. The zoom eyepiece comes out and any 1.25 in eyepiece goes in — a wide-field for sweeping, a short one for the Moon, or a nebula filter screwed into the barrel. No other scope in this group allows it.

Is the T-adapter ring the same T2 thread?

It is the same system: an M42 × 0.75 thread with a 55 mm flange distance, which a camera-specific T-ring converts to a bayonet. Supplying the ring removes one purchase from the imaging chain.
