Because a telescope magnifies and often only shows a very limited part of the sky at once, it is often very difficult to find something in the sky. A finder offers the solution.
The essence of a finder is that it is mounted parallel to the telescope. If the object you are looking for is in the center of the finder, then the object is also centered in the main telescope. The finder often has a cross hair or some kind of bullseye that may be illuminated.
There are different types of finders. A small telescope finder lets you see more than the naked eye and this helps you to locate that weak nebula you're looking for. We often refer to a finder telescope as a Finder Scope.
A Red Dot Finder (RDF) projects a small red dot on a non-magnifying glass. If the RDF is properly aligned to the telescope the object you're looking for can be viewed through the telescope as soon as the dot coincides with the object in the RDF.
A Telrad is a specific type of Red Dot Finder where the red dot has been replaced by a certain pattern that helps to navigate the sky. A Telrad is often used with larger Dobsonian telescopes.
A digital non visual polar alignment aid is a Polemaster or similar device.
All sorts of finders can be found in this category together with accessories for finders such as illumination and mounting material.

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.
Deze kabel speciaal voor een astrovakantie gekocht. De aanwezige montering had nog een DB9 aansluiting. De asi air werkt prima met de kabel, geen enkel probleem gehad. Aanrader!
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.
Ik begrijp niet waarom een scope als deze word beschouwd als beginners….er zijn plenty mensen die ver gevorderd zijn,die een prachtige scope als deze gebruiken.
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.
