Important update we received from Apertura: The telescope now has an updated primary mirror cell, new injection molded back cover, and a new larger focuser locking screw. On the first production run the primary mirror cell assembly was very sensitive to the mirror clip tension. Too much pressure on the clips resulted in the triangle shaped stars that you experienced. The new telescopes have an updated design and are now resistant to showing "Pinched Optics" even if the mirror clips are too tight. The most recent shipment and all the new shipments already come with these upgrades and we are calling customers who have the first release of the scope to get them the upgrade parts at no cost.
From what I understand the reason for the pinched optics is to protect the mirror during shipping. There are instructions to relieve the pressure on the mirror and is detailed in the manual.
The fact that Cuiv also had pinched optics means it's an issue at least some of these have, and I think it's ridiculous. It's supposed to be a basically image ready reflector and beginner friendly, and the last thing you want beginners doing is fixing pinched optics. They need to sort that out asap.
@@l.m2517The problem is that these scopes are made in China and quality will always be an issue. I've heard horror stories not only with this scope but with the Sharpstar HN130/150s' also. If your paying 2 or £300 for a scope I can sort of accept it (sort of) but these things are going on for 1 and £2,000!! They're having a laugh.
From what I understand they ship the mirror a little tight so that the mirror doesn't move around during shipping. When you get it you're supposed to take the mirror cell out and take a sheet of notebook paper and try to slide in between the rubber grips and the mirror and once it barely slips under the rubber grips you're good. Yes it's a little bit of work to do but would you rather have a broken mirror when it arrives at your house. I've had a huge issue with boxes showing up at my house that look like they've been thrown around.
@@PeterStaniforth no, if you want to know more email apertura or highpoint scientific they will tell you the same thing. I have the carbonstar and it is an exceptional scope.
He's using the ASI2600MC Duo. It integrates a separate guide sensor immediately above the primary APS-C sensor on the face of the camera itself. The system does everything from that guide chip while the APS-C sensor does pure imaging duties.
I have pinched optics as well, but damn does this thing make good photos! AM3, no counterweight, no issues. My only problem is I still don't think I really know how to collimate. I line the cross hairs up using the front adjustments and the dot with the rear. Seems to look good. Maybe. :)
He said 'a beginner Newt'. Those who are just getting started in astrophotography don't need to spend that much. Purchasing a used DSLR, wide angle lens, a 'star tracker' & a tripod will get you started.
