help with first setup with EQ6.
      #2593110 - 08/20/08 02:13 PM

Hi all just a couple of questions about setting up the EQ6.Do you use the bubble on the tripod or do you use a real level on top of the tripod to level it and how level does it need to be, exact or just close. Are we on daylight savings in the UK or not.And how accurate do you have to be with your latitude and longitude,my latitude is 51.52 and my longitude is 0.602 is the latitude North and the longitude East,thanks,,,,Paul.

I must confess that I have never even looked at that little bubble level because it really doesn't matter.

My pier is close to level and I sure don't waste time trying for anything better than that. The only reason to level the mount is to make it easier for polar alignment. If the mount is level, there is no interaction between the azimuth and latitude adjusting screws.

After the mount is polar aligned, it does not care if the tripod is level. At that point, the RA axis is "level" with the NCP and that's what counts.

It's always easier to align the mount if your lat/long are correct. The SynScan hand paddle goes to tenths of a minute and degrees. You can interpolate seconds and still be good.

Forgive me, it's been many years since I lived over there, but I do believe you are on BDT right now and Essex is east of Greenwich.

Hi Paul,

Although I've seen some of the bubble levels that were "close", the bubble level on my EQ6 (Orion Atlas, rather) was wildly off. I use a bubble level (now).

Although you will undoubtedly hear different opinions, it has been my experience that the "Alignment Successful" message comes most easily with carefully leveled mount, accurate polar alignment, and fairly precise lat/long.

I do not know if you are on Daylight Savings in the UK or not.

Hope this helps.

If you want to level it, the built-in bubble is fine. It really doesn't make a whole lot of difference.

We can take that a step further, actually, and say that it doesn't make any difference whether the mount is level _before_ it is polar aligned. Level has zero effect on polar alignment.

Thanks for that i may get the chance to test it on Friday if the clouds clear,,,Paul.

I'll try with some general information; if it is old news, please just read on by.

First, the hand controller GOTO technology is called SynScan. You may see SynTrek; this is the non-GOTO version.

The easiest setup for any location is to set the time to current UTC, offset = 0, and DST = NO. Of course, that means you need to know what UTC it is!

The level is hopeless on most EQ6s, as is the latitude setting for the elevation. The most accurate way to set the mechanical latitude prior to polar alignment is to use an inclinometer (the sort of thing used to check the angle of walls or shelves) and set it on the top plate without the OTA. But, as Uncle Rod observes above, level isn't critical if you use other methods for polar alignment. I try to use a level and inclinometer because my setup is quite mobile; at times, over 300 miles between setups. So, if I level and have a good inclinometer reference for elevation, I can get Polaris more easily into the polar scope. However, a 1-star alignment followed by a Polaris GOTO and then adjust the pointing with the mount mechanicals can also easily get Polaris into the polar scope.

You will need to enter your coordinates in the hand controller in hh mm for RA and dd mm for DEC. That's all the precision you can enter.

I assume you will be receiving the SynScan V3.xx firmware hand controller. When you receive it, power it up (it can be powered in a stand alone mode, without the mount) and verify you have one of the latest versions, V3.20 or newer. The source of the firmware upload software for your computer to update the hand controller, and for the latest firmware to upload, is:

Skywatcher SynScan Firmware Downloads

If you do not receive the latest user manual(s) with the kit, try:

Syscan Manuals


Download both the SynScan 3.0 and 3.11 files. In addition, you might want to download all of the firmware files, since some have version description files included. You might need all of the odds and ends to have the complete documentation.

I see you have a 10" LX-90; is this the OTA you will use? I converted my 10" LX-5 to the Atlas version of this mount. It's been fantastic for the last 2 1/2 years.

A final comment; there is a good source of EQ6 help and information on Yahoo. Check it out for a gold mine of information, and friendly, effective advice:

EQ6 Yahoo User Group

Well, there's a start. We could also raise the possibility of EQMOD. That's a fantastic resource for running the mount that opens a wide universe of possibilities, including satellite tracking.

all good advice the only advantage of leveling the tripod is that if you are level then when you make azimuth adjustments it has no effect on altitude and vice versa.

If you are not level this is not the case as the axes are "mixed" up and azimuth adjustments will effect the altitude and vice versa which if you drift align means you cant independently adjust the axes

Thanks again guys I’ve fitted the Losmandy dovetail plate to the OTA today and the EQ6 Losmandy head will be here in the morning,as soon as I fit that I will be up and running.Still shows clear skies tomorrow night so I hope to find out how it all works, if all goes well I will try the DMK as well,,,,,Paul.
