The angled-viewing Regal M2 65ED Spotting Scope from Celestron combines a high-transmission optical path with a nitrogen-filled magnesium-alloy housing to deliver reliable imaging performance at low light and in unforgiving weather conditions. At the core of the Regal M2 are fully multi-coated optics, including BAK4 prisms and an extra-low dispersion (ED) glass objective that minimizes chromatic aberration and maximizes light gathering. Multiple layers of Celestron's proprietary XLT coating on each lens preserve brightness and transmit contrast-rich images to the eyepiece.

This version of the Regal M2 spotting scope includes a 16-48x eyepiece that is ideal for intermediate- to long-range glassing. The broad magnification range, comfortable 20mm eye relief, and twist-up rubber eyecup make this zoom eyepiece well suited for long-duration observations. The scope's standard 1.25" eyepiece mount will accept most astronomy eyepieces, which enables a near-infinite number of optical configurations.

Complementing the image quality and weather-sealed construction of the Regal M2, several features enhance the scope's functionality and observer's user experience. An included T-adapter ring permits DSLR camera mounting to the objective assembly, transforming the 65ED into a high-transmission digiscoping platform. The rotating tripod collar has a 1/4"-20 mounting socket and is detented at multiple positions to provide the observer with alternate viewing orientations. A sliding sunshade, sighting aid, and dual-focus mechanism equip the Regal M2 with the functionality needed for a wide range of outdoor glassing applications.

How do you relate the magnification (in this case 16-48, as I understand it) to the specs of the Accessories Eyepieces? These are listed in mm, not magnification. Thanks
Asked by: John
To calculate the magnification, simply divide the focal length of the scope (382mm) by the focal length of the eyepiece used. For example, if you used a 10mm eyepiece, you would have a magnification of 38x.

A common criticism of this scope is that the mounting foot is too far forward. It appears that if the foot/support ring were turned around, the overall balance would be better. Can this be done by the user?
Asked by: John
Unfortunately, the foot/support ring cannot be turned around.

question

I have tried the following: Regal M2 -> t-adapter ring -> t-mount -> EOS-MFor testing I used a focus target taped to a wall and found that: - when the centre of the frame is in focus, there is slight blurring toward the edges - there is very noticeable pincushion distortionI realize that this may not be critical when digiscoping wildlife.Do these issues always appear when using a t-mount to hold your camera sensor up to an eyepiece?Is it possible that switching to a better/different eyepiece will avoid these issues?
Asked by: Anonymous
This is normal at times. It depends on the scope and how you are focusing in. The problem with switching the eyepiece you cannot thread the T-Adapter onto the eyepiece with the T-Ring. My apologies for this inconvenience. Also there might be some distortion because of the lighting?

question

Can the mounted scope rotate when attached to the tripod?
Asked by: MAURICE P.
Yes, the scope can be rotated by loosening the pan/tilt tension knob at the top of the tripod. Then use the pan/tilt handle to locate the object and tighten the knob when it is found.
