SVBONY MK105 Maksutov-Cassegrain Telescope Compact and Telescope

Product Description MK105 telescope; for planetary visual and planetary photography; for advanced planetary; binary star visual users and planetary photography users There is no chromatic aberration in imaging using the MK105 catadioptric astronomical telescope; the imaging principle of the astronomical telescope is the reflection of light; and there is no dispersion of light; so the entire optical system does not need to worry about the chromatic aberration of imaging; it is suitable for outdoor observation of celestial bodies such as the moon and planets The MK105 catadioptric astronomical telescope is compact and short; making it easy to carry around; for astronomical telescopes with the same focal length; the overall length of the telescope is only about half of that of the refractor telescope; the metal mirror body structure ensures the stability of the optical structure during transportation MK105's secondary mirror coating adopts high-reverse electrolyte coating technology; with a reflectivity as high as 99%; which greatly improves the imaging contrast of observation targets such as planets; at the same time; the tapered extinction tube design is adopted; the extinction efficiency is significantly improved; and stray light is prevented from interfering with the viewing experience The barrel of the MK105 telescope adopts the design of double star-seeking bases; one built-in base and one leaky base; which is convenient for customers to connect more necessary astronomical accessories; in addition; the lens barrel is equipped with a standard 75-degree mounting dovetail plate; which is easy to install and is compatible with mainstream brand equatorial mount mounting bases

105mm Aperture &1365mm Focal Length
The compact telescope features 105mm large aperture and 1365mm long focal length. And that ensures great amount of light entering the telescope and high resolution, an ideal scope for making detailed lunar, and planetary observations.

99% Reflectivity Dielectric Coatings
Maksutove telescope largely reduces aberrations and renders crisp and clear views. Meanwhile the MK105’s high quality meniscus lens (fully multi-coated), primary mirror (multi-coated of precision aluminum coating) and the secondary mirror (99% reflectivity dielectric coatings and multi coating) ensure high transmittance, high reflectivity and high contrast.

Compact and Portable
A perfect transportable, grab-and-go telescope, easy to pack in a bag, and with its sturdy metal construction it will be sure to survive a few bumps and knocks on its travels.

Conical Extinction Tube for Stray Light Elimination
Utilizing Conical extinction tube prevent stray light from interfering with your viewing experience.

160mm Vixen-style Dovetail Plate
The mount rail is of a Vixen style dovetail design to easy attach, and the screw holes size are 1/4” and 3/8”, compatible with plenty of mounts and tripods.

Dual Dovetail Mounting Base
Dual dovetail mounting base design is available for more than one finderscope to attach and brings great convenience for conditions like there requires the finderscope’s position to be changed when you match the telescope to a different mount.

MK105 Maksutov-Cassegrain telescope exchanges the conventional front corrector plate of a Schmidt with a convex meniscus lens, resulting in a smaller secondary mirror that limits obstruction and increases contrast, while eliminating the need for periodic collimation. New feedback about MK105! It has now been almost 5 months since we released the MK105 telescope, and we have hundreds of customers who got it and are using it to capture planets and the sun, and even try to do some simple deepspace observation. How does it perform? Or maybe you're interested in it now, but still concerned about its quality, yes, it has had some negative reviews, but most of the issues have been clarified and resolved. We've rounded up some of the recent feedback about it, and let's see what they said. Bruce Stoneman ---- Svbony MK105 105mm Maksutov-Cassegrain telescope (the 2 close up images) SV48 90mm Achromatic doublet telescope (the full disk (blah) and most of the sun) SV305pro planetary camera Svbony eyepiece extension tube (needed for focusing sv48) Baader "white" polymer solar filter sheet Svbony UV IR cut filter Svbony .5 focal reducer for the full sun on the sv48 (the image wasn't great) Taken from a deck on a second floor condo so was easy to switch telescopes. I added color to 3 images left one as is (purple tint from one of the filter settings in firecapture) Harry Ellingsen My setup with MK105 and SV305. Did some modifications with remote control of focus and clock drive. Works perfect 松本龍郎 Somluck RungAree --- Celestron NEXYZ 3‑axis universal smartphone adapter Svbony MK105 Paul E. Cizdziel ---- I have been impressed with the visual performance of the MK105. I like it! But recently I tried to do some imaging with it on a few star clusters. For someone like me who is used to smaller refractors (SV503 80ED is my largest scope), it was difficult to "handle" the MK105 in astrophotography. At a focal length of 1365mm under Bortle class 7+ skies, plate solving did not work due to lack of stars (presumably?). So I needed to plate-solve with an aligned smaller guide scope (no problem). In addition, I could not get guiding accuracy low enough that night to be suitable for such a high focal length. Also DSS would not stack most of the images due to a lack of stars. Finally, in the 2 images below, you can see what appears to be a bit of a coma effect in the stars. Is this a collimation issue? However, if I intentionally put the stars out-of-focus tthere are nicely concentric donuts shapes on the bright stars, which I thought meant good collimation? So is this possibly an out-of-focus issue? I did not anticipate all these challenges with trying to use the MK105 for astrophotography. Like I said, it's really great for visual use, but so far I am a bit frustrated with astrophotography. Any comments or suggestions would be helpful. I intend to keep trying!
