Lou, while I am sure that Rick could tell you, I checked Ed Ting's review of the 11 inch EL, and it was written in December 2000. Hope that helps. Bill Jensen...
And to narrow that age down, I purchased my 12.5" Starmaster in spring/summer of 1999 and that was *before* the EL model was being manufactured (mine is a...
If you'll contact Carl Zambuto, he has a record of each of his mirrors. He can tell you exactly when it was coated. You can easily communicate with him through...
I posted this on the Zambuto mirror site and thought it would be very appropriate for the Starmaster site. I posted this earlier this evening: "This first...
... Lou, Take your mirror out of the telescope... On the back Carl inscribed the date of manufacture, the serial number, and the focal length. Paul -- Paul...
Bob, congratulations on an incredible night of viewing! It's those rare evenings, when all the stars align, so to speak, that keep us energized for years to...
Bob Thanks for sharing that with the Mid Westerners that have never experienced those type of skies. I hope to run my 24"SM up till I have no more glass to...
I have an old SM EL 11 with Astrosystems 8132 step enoders and hardware and a Discovery 12.5" truss with the old 4000 step (tangent) encoders. I use an old Sky...
Yes, kind of confusing. I may have detected the slight problem. I mounted my altitude encoder on the Starmaster metal label with double sided tape. I did this...
The type of errors that the AN corrects for are when the mount itself is not square. If something about the encoder mounting is squirrely, that can casue ...
Hi Lou, As Tim has pointed out, encoders do come with various resolutions, including 4000, 4096, 5000, 8000, 8192 and 10,000 steps. You might want to check if...
Gary, I appreciate your reply along with the others. I spent some time studying your manual for the AN and it appeared to me that it could help with the type...
Hi Lou, Thanks for the post. Argo Navis allows you to align on *any* object, including the approx. 30,000 in-built objects as well as any of your own user...
I have the 14.5-inch with the Sky Tracker Go-To feature. The motors are powered by YUASA NP7-12 sealed lead acid batteries. Rick supplied a 500 ma battery...
... How long did it last? ... I hope you don't take this the wrong way. I am in no way trying to make fun of you or anything like that but maybe you are...
I have two batteries. The one that died lasted only about 4 hours of intermittent operation. It had previously lasted for 6 weeks of intermittent use (as...
Same as Mike, using the charger Rick supplied, I normally charge the battery for 12 hours. One battery is 6 years old and still kicking, while the other just...
The Vector Smart 2 amp 12V battey Charger is a two stage which can be used on all types: deep cycle, AGM, Gel, Standard Auto, etc. It will never overcharge,...
... A battery should not be drained below 50% charge, so 500ma over 8 hours is at least roughly correct, but it's important to note that the 500ma is a rating ...
Hello all, If you read on the side of the battery it will gives voltages for charging. You should adhere to the recommended max voltage to decide when it is...
... You don't even need to put it in stand-by mode to swap batteries. If you're powering the SC with the 12V battery, leave the 9V internal battery in and it...
... battery ... Actually I do power the SC with an external 12v battery. I have a battery mounted in the mirror box that powers the Sky Commander, the...
Apologies to the list if this has been discussed before. I notice on the Starmaster website the banner "Special Model Closeout Sale on the 10 inch f6 Hybrid"....
Keith, I talked with Rick, the owner of Starmaster today and he said that it is surprising that the 10" f/6 that many people had expressed an interest for has...
Keith, Starmaster has updated their website and is now listing how much of a discount they are giving on the 10" f/6 Hybrids. They also announced a 24" and...
I have a Starmaster 12.5" ELT which I love. I have noticed however that at about 45 deg. elevation it has has a very bad case of the shakes if I touch the...
Tim, I had that happen on mine. What is causing that is that the mirror becomes perfectly balanced in a relatively unsupported moment and it starts to...
