Gavin -- I have a Losmandy dovetail attached to the top of my Parallax rings holding a Meade 16" LX200GPS OTA. On the rail rides a Tak FC-100. The FC-100 is a doublet, and considerably smaller

The Mach 1 is reviewed in New Products in the Dec. issue, page 37, entitled "Staying on Track" ... A good read .... Dave

Hello I have a 14" LX200R attached to an AP1200 using a set of Parallax Instruments rings. The setup is housed in my observatory and I'm very happy with it. I was wondering whether I could attach a

The Nov issue of S&T has just arrived and the "next month's contents" does not mention it. Likewise the contents list for the Dec issue of Sky &Telescope, vol 114, No 6 on the "www.skypub.com"

Hi Dean, I have the 48" port. pier that I use when I go to my ranch. My imaging scope is either my TOA 130 or the FSQ. Check out my web site. www.astrodave.com/oharra Tom O'Harra about the

Hi Joe, I come from the school of thought in astrophotography that there is no substitude for stiffness, like in auto racing there's no substitute for cubic inches. A lot of ideas for astro

Hi Don, My engineering background reminds me of these pitfalls as well, and it is a concern at the back of my mind, but I still wonder how much stiffness in this application, is really enough.

Hi Joe, I really don't think PVC pipe buried in the soil is going to be a very good pier. The ringing that you mention is a high frequency tone, that the PVC pipe wouldn't have compared to a metal

Hi All, While waiting for my new mount to get finished, I am thinking about the portable pier height. Currently mine is about 38" and the 1200 mount is 2" taller, so if I had a 36" tall AP pier it

Hi, The other benefit, I was considering, is that it can be sawn to length, with some work. However, you can do a deal with a contractor doing road work, and he will cut one evenly, to your

I went with a portable pier from Particle Wave Technologies for my Mach1GTO/TEC-140 combo, the Monolith LT with 12" extension. The LT heritage from the flagship Monolith pier is unmistakable, as is

The bending can be captured using strain guages (gages for US speakers) Would anyone be prepared to give all of this a go ? I liked the idea of the 10" concrete drain pipe - I cannot see that

You are trying to measure the motion of the pier. Use an accelerometer, not a microphone. a mic to port.

Can anyone tell me if version 4.12 of the GTO Keypad firmware is still shipping with the current Mach1GTO mount or has there been an update released? I read somewhere that it is to be updated soon.

Todd, See my answer on the ap-ug site. Larry power to

I'll be listening closely to this one as my Mach1 mount will be delivered shortly too. I just dont have the scope or camera you have so I may opt for the aluminum tripod. Todd

Larry, What are you putting you mount on? What tripod? Todd wrote: volts DC supply be
