A telescope looks at celestial bodies and at the same time it is looking through a thick layer of air. Unfortunately we do not have much influence on the quality of the air. What we can influence is the quality of the air in the telescope itself.
This quality and in particular the temperature of the air has a major influence on the quality of the image produced by the telescope. You can compare this effect with the vortices above an asphalt road on a hot summer day. A telescope only performs optimally when the optics of the telescope have cooled to ambient temperature. As a result, the temperature differences between the air and the glass of the telescope are eliminated and warm air flow coming from the optic does no longer disturb the image.
In order to allow the optics, not to mention the air in the telescope tube, to cool down faster, a specially suitable cooling system can be used. These cooling devices allow cooler outside air to circulate through the telescope tube. This causes the telescope tube including optics to be much faster at ambient temperature resulting you to be able to start the observation session earlier!

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.
