Does the Polemaster software account for the fact that the Earth's rotational axis does not point exactly at Polaris? Don Anderson

Understood. I will likely get a new laptop (Win 10) to use as my main astro imaging platform and relegate my 5 yr old Win 7 machine to a backup role. In the mean time, I will get the old XP machine up

Ray I dusted off my XP SP3 backup laptop and upgraded the driver as well as other astronomy software and I noted that I could not use the driver utilities unless I have .net framework 4xx installed. I

Just for the record, Al Nagler has stated that there is no problem using their NP scopes for solar viewing with a wedge. The rear elements are far enough forward in the light path that there is no hea

Ignore the last question Ray. I just read all the threads and got my answer. Thanks Don Anderson

So as I understand it from the Microsoft site it only affects access to the help files and doesn't affect the operation of the program. Is that correct? Don Anderson

Ok thanks Ray. Will check it out. Need to get a new main laptop and get rid of the 15 yr old XP anyway. Don Anderson

Ray I was going to try a Pempro run on my AP900 mount using an older XP Service Pack3 backup laptop (main one being fixed) I tried upgrading to build 136 from Build 135 and got the following error "er

Back in early March I queried Marj about whether an upgrade would be offered for the 900/1200 series mounts. She said no. Not surprising since to do so would negate one of the most powerful inducement

Of course. That makes sense. Sent from Don's iPhone

Great Pic of the Zodiacal Light Roland. Just wondering, is the faint streak just above the hill (lower right about 1" above the hill) a comet? Don Anderson

Vince What you describe sounds more like a clutch plug problem rather than a grease problem. Grease would not cause the degree of stiffness that you describe. I would get hold of George at AP and go o

Marj Would it be possible to retrofit-equip home/limit switch capability on 900/1200 mounts upgraded with the CP-4 utilizing possibly some type of magnetic reed or optical switch affixed to the RA & D

Get a second laptop. They are cheap!

Yes, when the natural rubber decays, it could be difficult to extract. Maybe a stick pin with the end bent into a hook would work. I suspect your estimate of a year life for the elastic could be gener
