There is the Explore Scientific GoTo system which can be retrofitted to G-11 mounts. It uses stepper motors that are not noisy. The best information about this that I have found is at:

Thanks!

I noticed that Telescope Express sells stepper motors:


for another GoTo-system:

Hadn't seen that before. Not that I wish to exchange my G1, but perhaps when the day comes that want to...:)

Sorry for my detour. Back to subject.

Re: Just purchased GM811GHD

 

Thank you all for the help! I just got my GM811GHD!?

I bought a large rolling toolbox from home depot and bought some foam online to make a cheap but protective case such as the pelican cases (not airline safe though). I'll use this for the RA and DEC axis' and any smaller accessories. I got an Orion padded telescope case to carry the HD tripod around (that thing is a beast). Luckily my apartments have an elevator so rolling/carrying these down won't be too difficult.?

I also just purchased a QHY Polemaster that will come in the mail this week.?

Still deciding on if I need to get the RA extension yet. Might try to machine something myself to do something similar.?

Next will be to figure out how to DIY a portable 12V battery pack?

I'll probably make a more detailed post on how I DIY'd my carrying solution for the mount + tripod.

Can't wait for clear skies to try everything out!

Magnus,

The stepper motors are the original motors used on the G11, they do not support Go To, just tracking and guiding.

I replaced them only because I wanted to remotely control my telescope.

They are still available as an option on the web site.

Re: Polar Scope

 

Agree, PoleMaster is quick, easy and accurate.

Chip,

It¡¯s funny you should say that, the first thing that people comment about when they see my tucked in motors is ¡°they are a lot quieter than normal¡±.

I hadn¡¯t noticed because I moved from the stepper motors, which are effectively silent.

Regards

Hi Dale,


I will say this about the tucked motors, they made my standard G11 with Gemini 2-mini and latest high-torque motors a lot narrower and surprisingly a lot quieter for some reason. Combined with the RAEXK the need to do a meridian flip to prevent a mount strike happens a lot less often while imaging. For this it was WELL WORTH the money IMO and I'm really cheap which is why I bought a used G11 in the first place!?

I need to make a distinction here: I'm cheap which is not the same as being tight. Cheap people just want to get a good deal without hurting or limiting the potential of their gear. Cheap people know how to shop and identify the best possible gear and what a good deal is on it and then buy it. Tight people just keep buying inexpensive gear and suffer, endlessly upgrading until they become - cheap people!?

Been there, done that!

Re: finderscope bracket

 


I have a Losmandy polar scope on my smaller Losmandy the GM8 and it works very well for visual use but if imaging it's not good enough without additional work using the drift method, SharpCap or PHD2 and at that point why bother? I've tested and used?new Sharpcap 3.1, PHD2 and PoleMaster and IMO the dedicated PoleMaster is very accurate and faster. I much prefer it over the other methods for the simpler computer guided visual alignment method used.? YMMV but I just go with the now (early drivers had issues under Win10) painless PoleMaster.?

I'll add my two cents on polemaster.? For those of us having arthritic issues with bending down and having your neck at an odd angle, the polemaster is the best ever.? One downer is having to use a laptop to polar align.? If you are in a group and people are trying to get their night vision going, a blazing laptop screen can be irritating.??

I would have to agree with Brian. When you get the polar scope you have to align it. That gets frustrating. I had one I know. I went to the Polemaster for like $10 more and found it's a whole lot easier. Just my 2 cents.

Re: Polar Scope

 

if you're looking to save money, you might try the new polar align assist built in to PHD2, the latest dev release. it's free

I did some research on both the Polemaster and Sharpcap. Sharpcap is pretty inexpensive, so I may give that a try first. No point in buying another camera if I don't need to.

Re: G11 cable management

 

Hi Chip,

Thank you for all that information about the temperature and it's effects on the worm-gear drive train.? I think? I'm just? sensitve to having to spend money on a mount that's only 18 months old.?? Maybe I can coordinate a trip down the coast with getting it scheduled with Scott.? The tucked motors and new OPW on the DEC axis are attractive to me.

Thanks again.
Dale
Re: G11 cable management

 

Paul,

One of the reasons I bought the mount was because of the reputation for support and innovation.? I too think the system is very good.? Maybe I'm just a bit sensitive because my mount is only 18 months old and I wish it had tucked motors.?

Re: High precison worm vs OPW-11?

 

Here's an example of a tuck motor mod.??
Re: Polar Scope

 

I also bought the Polemaster. It works and it is
much more comfortable to look at the computer
screen than to crouch down low behind the mount
-- which, unless you live close to the equator
you will have to do -- and the further north you
are, the more uncomfortable the position is.

If you already have an astro camera (not a DSLR)
there is also a method called Sharpcap that I
have seen highly praised, though I havent tried
it. It also uses software and is apparently even
simpler than Polemaster:

Personally i'd recommend getting Polemaster from QHY. it will save you time and sanity.

Polar Scope

 

I am seriously considering a GM811G mount. The polar alignment scope is an option. Do I need this or does the Gemini 2 do an adequate job of alignment without it? How about time required to do initial alignment and follow up fine tuning for astrophotography?

Hi Don,

Can you elaborate on your drive setup? I mean, do you use dc serve motors tucked under with a belt drive?
