Re: GM8 lubrication

 

Moly greases are great in their place -- very high load bearings and sliding contacts.? But neither the GM-8 or 11 have any surfaces that are that heavily loaded.? In addition, the matrix that Moly greases use is not that different that lithium greases tends and tends to dry out leaving a rather cake-like residue.

Go with a synthetic grease designed for wide ranging temperatures.? Super Lube is fine (although I think the addition of the Teflon particles is overblown/overrated) as are several other synthetic greases.

Pre purchase questions GM811G

 

Hi all,
New member here.? I have settled on the GM811G with HD tripod and have a few questions.? In no particular order, they are:
1. I plan to autoguide with my ASI120mm camera to the mount's ST4 port via laptop or the the ASIAIR Pro, but am not familiar with the TTL connection.? What is the difference between ST4 and TTL and is there an adapter needed here?
2. Can my Polemaster function with the mount (assuming there is an adapter)?
3. Are any components sourced from China?
4. Will the HD mount will ride on my Scope Buggy without modification?? I did not note any dimensional information on the website.
5. The Losmandy website indicates that this mount is in stock.? I will want some accessories such as the RA Ext Kit and GPS.? If one placed an order today, approx how long for shipment?

I am sure there will be more.? Your indulgence is appreciated.


Safety limits

Tony Gabriele
 

I need to change my safety limits as the telescope does not slew to a given point in Carte du Ciel given the "Invalid DEC coordinate" error which I understand is a gemini ascot error message. There is a Losmandy video on how to change the values but its not clear what I would change them to.
Suggestions?

True. They're expensive but you get sun reflective coatings outside and dew suppression rubberized coatings on the inside. Plastic inside alone would provide nucleation sites for dew.?

I found motorbike covers from ebay come in different sizes and shapes and work a treat. Telegizmo is niche and overpriced BBQ covers IMHO. These days every accessory that has the word "astro" or "telescope" has an insane mark up. Another tip if you're looking for cylindrical bags to carry your tubes look no further than drum sets bags. They're good quality, heavy duty and great padded carry bags.

I am using Superlube in my GM-8, works great. But I also have a can of industrial moly grease that I used to use on the brakes in a high performance sports sedan many years ago. It seems to plate itself on any metal surface -- was curious if this might be usable as well?

Thanks,

I use the MP50 on the spur gear. I find it keeps the worm wet and has a nice consistency. But nowhere else.

Re: Polar alignment scope light alternative

 

It came from ebay, basically a battery box with a wire and flashing led, I didn't see a non flashing version but sure there would be.


Re: Polar alignment scope light alternative

 

I could only see the video when i .logged in to the forums

that looks like it would work. is there a non-flashing version? i feel like i might get seizures looking at that for too long!


Polar alignment scope light alternative

 
Edited

Hi all, this is the flashing led I spoke about a week or so ago for the Polar scope, have not had the chance to try it due to rain etc but hope it will work ok.?hope the video plays ok


Re: Cover for G11 with 9.25 SCT and guide scope

 

Bought a large reflective tarp (silver one side, blue the other), folded it in half with the silver side out and asked wifey to sew up the ends making a sufficiently large and inexpensive cover. Use it inside my ROR observatory for the telescope and GM811G mount.

+1 for telegizmos covers

I leave my scopes out 24/7 365, including rain and lately temperatures up to 118F (you read that right) and my scopes and equipment have weathered it just fine (pun intended haha)

I also added a bit of radiant heat shield to the top to avoid the sun beating on it too much

Ideally, I'm looking for something discreet, e.g. green in colour (which I know is not ideal) but that's not a showstopper. I was recommended the Telegizmos cover for 12-14" EQ/GEM mounted SCTs. That sounds like it might be too bog (and I don't want loose covers flapping about). Until I get a ROR built I envisage leaving the setup out for a couple of weeks at a time if not more (depending on weather). Once I have the ROR the cover would be used for camps, dark site visits, etc. Suggestions welcome.

Re: PHD2/G11T connection problems

 

Nice work Jeff

As I recall, you did a major upgrade into some really long focal lengths, so getting even this far is a pretty big step forward

What are you trying to accomplish?? Get PHD2 auto-guiding working -or- control the mount -or- start up the mount?

Carte du Ciel & GM8+Gemini 2

Tony Gabriele
 

I want to use Carte du Ciel to control my Gemini. I first do a Gemini startup and confirm all coordinates using the GPS satellite attachment. So times & coordinates are correct pointing to Polaris. I set it as my home position with the Gemini and then connect the Carte du Ciel.?
Unfortunately when I ask the scope to slew it goes in the opposite direction.?
Any ideas how to correct?


Re: GM8 lubrication

 

I've just used SuperLube (PTFE) on my G11. Too early to say but I am expecting it to be fine.


Re: Counterweight bar safety screw

 

Thanks. I have some of those screws at hand so will try to find a suitable washer.


Re: Counterweight bar safety screw

 

Thanks all, it might help if I spelt the name correctly!?


Re: Purchase question.

Richard Benoit
 

I bought my G811 in March from High Point Scientific but it was shipped directly from Losmandy so I know it was properly adjusted. I've bought some additional parts direct from Losmandy as I found a need for them. Their customer service is great and they respond promptly if you have any questions or comments.

Richard


Re: Purchase question.

 

Hi Stosh

Here are a couple thoughts for you:

all dealers have the identical product. They sell packaged solutions

Losmandy direct has the (relatively new) option of configurable mounts, so if you want something specific you can choose the options, and maybe save some $$ depending on the options you get ?

the flip side is we are way backordered on all mounts. Interest in astronomy has just been.... astronomical (for lack of better word, or perhaps the perfect word ha!)?

Scott personally hand tunes each mount that goes out, and I'm fairly certain the resellers do not do any additional QC efforts (at least afaik)

I’ve been doing lots of research, and I’ve decided that the G11G with the HD Tripod is the correct mount for my current and future requirements. ? The price is the same at every authorized vendor I’ve checked, but some vendors don’t seem to charge out of state tax and some offer free shipping. ? Aside from this, is there any reason to order from a particular vendor or from Losmandy itself? ? Shipping speed and having to wait on back orders is not a concern for me.? I’m more interested to know if certain vendors are known to qualify control the mount before shipping or are known to better package the mount to prevent shipping damage.

Thanks.
