Losmandy GOTO vs ??
Jay Stanley
With all the hoopla about the new GOTO Losmandy system I wondered if
anyone else used one of the other aftermarket Losmandy GOTO retrofits like "AIM Control" () or Skywalker"() They talk about servo based vs "brushless" motors..etc. What about accuracy, easy of use and alignment procedures? Thanks Jay |
I have been using the Skywalker II from Astrometric instruments on a
G11 for months now and it is a fantastic system. It needs a computer for full goto control, and is compatible with theSky V5. The microstepper motors track almost silently and it slews at 6 degreees per second with the sweetest singing I have heard from a telescope drive system. Astrometrics customer service is second to none and the system is very well built with the Losmandy retrokit perfectly engineered to match the mount with no problems. It has loads of features, the only drawback of which, is that some of them are still being implemented in software. Even as a drive corrector only (with no computer attached) it is a quantum leap over the standard Losmandy drive system. I am very happy with it!

Greg,
By drive corrector, I mean just a hand paddle with the ability to control the drives at varying speeds. Similarly to the standard Losmandy drive system. Astrometric have implemented TPoint with the Skywalker, but I am not sure if it's part of the latest systems or requires the purchase of TPoint seperately. I think it will probably run on the same PC as the SkyGuide software which is the very comprehensive controlling software for the Skywalker. Without a PC, the permanent error correction is not implemented. I beleive Astrometric are currently working on a completely stand- alone system, self-cointained in the hand-paddle, ala Sky Sensor 2000, Losmandy, etc. Eddie Trimarchi ~~~~~~~~~~~~~~~ Quoting Greg Crawford <gc@...>: Eddie,version of TPoint. Does the Astrometrics version have something similar? Isthis what you mean by drive corrector? |

Eddie, do you have any images on your web site taken with this new drive yet? Rockett Crawford ---------------------------------------------------------------------------- Capella's Observatory (CCD Imaging) |

Hi Rockett,

All of the images I have taken with the C11 this year has been with the SW2 control system. I have posted them to abpa over the months, but as yet don't have any one my web page. If you want to see them again, I will see about posting them to my page. I just managed to get my mount tracking well then i had to return my C11 to the shop. So I am scopeles for a while.

Regardless of the hoopla, the price of the system is quite amazing.
Consider the following based on Pocono's pricing. G-11 Package with Polar Scope $1895 G-8 Package with Polar Scope is $1449 G-8 (same as G-11) electronics package separately is $400 G-8 without electronics is about $900 G-8 Polar Scope is $145 G-8 Package if bought seprately is $1445. Now DSCs are $595 DSC Delrin covers are $70 (which I'm told you should buy) Aluminum Motor Covers are $79 (which I'm told one should also buy) Total for these is $744 and they are not needed with the GOTO, if I understand correctly. G-11 package with DSCs and 2 sets of covers = $2643 G-8 package with DSCs and 2 sets of covers = $2193 Difference to get GOTO with its features: G-11: $3195-$2643 = $552 G-8: $2495-$2193 = $302 So for $300 on the GM-8 and $550 on the G-11 you get GOTO. That's very nice, especially for the GM-8 I would say, unless I'm missing something here. The GM-8 is normally about $445 less than the G-11, but with GoTo on a GM-8 only costing $302, the Goto version is about $700 less than a G-11. That makes the GM-8 quite a buy I would say. Now if this system also eliminates the motor problems and "periodic error" problems that appear to be associated with the current motors, then this is a very good upgrade. The SkyWalker II + G-11 Combo is $3595 (about $400 more, so that's about a $950 upgrade over the base G-11 with DSCs). It will be interesting to see how the Losmandy GOTO compares with the SkyWalker although one thing I like about the skywalker is the ability to manually move the scope without the scope loosing position since all positioning info comes from the encoders and also it can uses TPoint adjustment values. Even better, if you can't afford it all at one go and don't mind tracking manually for a while, is that if you buy just a G-8 mount with no electronics, you add the GoTo later for the same total price as the GoTo package. From what I hear the GM-8 mount only comes with manual slow motion knobs in place of the motors (which would be nice to have any way if the power dies). It seems that G-11 isn't sold as just a mount, so you've got to shell out the extra $400+79 for the electronics as part of the mount price at the begining, even though you'll junk this gear if you get the GoTo later. So what am I missing here? Is the GM-8 GoTo much more than an equivelant GP-DX system? (Can't seem to find prices for GP-DX GoTo equipment anywhere) --- In Losmandy_users@..., "Jay Stanley" <jstanley@m...> wrote: With all the hoopla about the new GOTO Losmandy system I wonderedif anyone else used one of the other aftermarket Losmandy GOTOretrofits like "AIM Control" () or |
