Reviews & Ratings for Konus Digimax-90 Telescope 1770 — 2 reviews — Page 1

Bought this Konus Digimax 90mm second hand and didn't pay much for it. New retail is a bit steep in my mind for this, but an excellent value used.

My other telescope, for reference, is an 8 inch reflector Orion SkyView Pro.

Very pleased with the terrestrial and the planetary viewing of the Digimax. Came with no name (Konus) 17mm and 10mm EPs. The 10mm is a bit unclear for my viewing taste, but the 17mm is one of the clearest in my EP collection, comparing well in clarity to my Orion 25mm Sirius plossl. Better clarity than my Orion 20mm Expanse and 6mm Expanse and 4mm University. I used the 17mm with an Orion Shorty Barlow and the image was still clearer than with my 10mm, 6mm, and 4mm EPs alone.

I have the 20mm and 15mm Orbinar (Seben) Plossls, and they are both less clear and fuzzy so will likely use them mostly for terrestrial viewing. The 10mm Orion Sirius beats the 10mm generic (Konus) provided with my Digimax in image clarity as well.

There is no fine adjust control on this scope for positioning, so tapping with my hand is the best method for "fine adjustments" and then waiting for the scope to top shaking. The Skyview has fine control knobs for subtle position adjustment which is very useful. Jupiter was surprisingly close in image quality on the Digimax to my SkyView, but the Skyview is easier to locate and track with than this Konus, particularly at higher magnifications. Clarity is better on the 8 inch as would be expected at the higher mags.

Good quality optics and the motor drive system works smoothly. Clear and easy to follow setup. Included accessories are decent quality. The only problems are finding additional accessories for it and it does not come with an AC power adapter so you must use batteries and try to find one that will work. I would recommend this telescope for novice to intermediate users.
Pros: Good optics, easy to use, included accessories
Cons: Additional accessories
