For maximum performance, the primary and secondary mirrors of your telescope must be properly lined up, or collimated. Collimation of an SCT telescope is usually accomplished by adjusting three screws on the secondary mirror housing to tilt the secondary mirror on its mounting plate until the image at the eyepiece appears undistorted. For Newtonian-style telescopes, including the Schmidt-Newtonian and Maksutov-Newtonian, collimation is usually accomplished by adjusting the secondary diagonal mirror, followed by the primary mirror, using a laser collimator or other collimation aid. Collimation is critical and often needs to be done each time the scope is moved.
Unfortunately, collimating a telescope with the factory screws can be frustrating because of the need to probe for the screws with an Allen wrench or Phillips screwdriver in the dark, and the difficulty of manipulating tools while looking through the eyepiece to judge the effects of the adjustments. Bob’s Knobs greatly simplify the collimation process by replacing the factory screws with thumbscrews. While looking through the eyepiece you can reach around on most scopes and quickly adjust collimation without tools.

Goede kwaliteit van product, nadelen zijn de battery cover en de polar scope illuminator, die beiden van plastic gemaakt zijn en niet een stevige indruk maken. De battery cover zat eerst vast bij mijn SWSAii, werd snel gefixt in de winkel zonder enig probleem. Zeer gemakkelijk om te gebruiken, denk wel aan een stevig statief voor het kopen van deze startracker.
I love this EQMOD Cable, because I can use all my "old" software on my Windows Computer without any change. EQMOD is my ACSOM driver for years now.
I mainly use APT, SharpCap, and Cartes du Ciel.
Thank You for a woderful product at a fair price.
Since many years I own a high-quality 102 mm refractor which I used on a very old mount which had tracking in RA but nothing else. And it was ok to use the refractor visually, but you shouldn't touch anything... I always dreamt of a light-weight mount to step up a bit. An important criterion was that it shouldn't be too big and heavy - I want all my equipment in one Zarges box, 80 x 40 x 40 cm3. I found the perfect mount with the AVX. It is probably stable enough to hold a much larger telescope - with my 102 mm refractor it is rock solid. The handbox is nice and compact, which I prefer to some of the competitors. I even started using the Goto, even though I am almost 60 years old, but it is simple and works well. Note: Do *not* buy the polar scope. At least in NL you can't really look through it, as the adjustment knob for the elevation is in the way (see the picture attached). You don't really need it anyway, as the handbox allows to align the polar axis. Summary: I am happy, and the price is reasonable too.
The quality of this scope is amazing and it is strong when it comes to viewing or/and taking footage of the moon planets or even nebulas…using either a smartphone or deep sky camera….
So 5 stars for Robtics and this telescope
Fijne telescoop voor astrofotografie.
De finderscope leek onscherp en na contact met Robtics bleek de zoeker scherp te stellen door het voorste zwarte gedeelte te draaien en weer vast te zetten met aandrukring.
Je hebt wel echt een coma corrector nodig.
