It is an Antares secondary to be installed in a Teeter Dob that should deliver here in the next month or so. They're still out there. But everything else is approximately crazy these days so you might have to keep trying for longer than normal. (Whatever that was.)   

 

If you learn of changes,please let us know.

 

I have a couple of their secondaries and they are

Definitely in business and still rocking

 

But when I placed my first order over a year ago, I didn't get any reply from Antares. After more attempts of communication from another email address Frederic finally answered and it turned out that my first email somehow landed in the spam folder. So maybe better to call.

With my second order this April - because of the covid thing - USPS kept the package for three months (so the tracking info said) before the secondary went further and finally reached me in July.

 

 I highly recommend Antares secondaries

I placed the order yesterday and that was it.  I'll wait a couple of days for confirmation from them (Paypal already confirmed) before bugging them.

I've bought 3 from him the past year and they all showed up within 5-10 days, no confirmation emails. I wouldn't worry about it for at least that long.

Anyone know how thick their 3", 3.5", or 4" secondaries are?

Also, are they bk7 or borofloat?

I can only measure the portion I can see through the secondary holder which is at the major axis end of the secondary. It is 27mm thick at that point on my 3.5” mirror.

 

Antares make their secondaries from Pyrex/Borosilicate. They occasionally make some from quartz.

Borosilicate can be BK7 or Pyrex. GSO says borosilicate but also specifies BK7. As long as Antares specifies Pyrex, that is a plus.

27mm/1.41 is 19mm. At least that is 1mm thinner than the GSO 88mm secondary, which is 20mm.
