Well my new "toy" mount arrived. Being Ramadan no time to play play with it.
Got it from penang vendor ( no relation except for a satisfied customer) the whole lot with all accessories. Will be used on the Gitzo tripod.
For those who like them small.
This you tube describes it very well.

Certainly a very portable EQ mount but without a goto.

I have some photos here:

I used it in the UK (where Polaris is gloriously high in the sky) and so polar alignment was fairly easy. 2-minute subs at 200mm were not so bad, a better polar alignment would certainly help (and a better tripod than the Benro A350EX I was using).
mymoon, can you share where you purchased it? and did you get the counterweight shaft and weight? I got mine from The Widescreen Centre in London, it was 299 UKP and the CW and shaft haven't shipped yet.

Re: Skywatcher star adventurer
I see that you have play-play with the "toy". I was there too around the QE birthday and the naked bicycle ride around London. But the delivery dates are not suitable for me. So I opt to purchase locally.orly_andico wrote:

Here unfortunately we may have to do drift alignment using the Robert Vice DSLR method. But using an autoguider (it does have an autoguider port) maybe a compass and inclinometer method will be sufficient for up to Canon 400mm f/5.6.
I notice too there is a mechanical DEC fine positioner and an electrical RA fine positioner(12X) to help position the stars for the drift alignment.
I got the complete set including counterweights and shaft from here

Re: Skywatcher star adventurer
1700 MYR = 664 SGD.
So almost exactly what I paid (306 GBP = 645 SGD).
Considering that you already got the counterweight and shaft, you got a better deal, because I now have to pay for onward shipping of the CW and shaft from UK to SG via SingPost/vPost.
I just measured the periodic error, it's about 23" p-p with a 15-minute period. Not bad actually.. typical China mount performance.

Question:
I note on other boards some discussion on equatorial mount's periodic error and how it can be reduced. Can it be done with this mount ?
More pertinent is it worthwhile.

Re: Skywatcher star adventurer
Somebody in stargazers lounge has taken it apart.
There is no PEC indexer. Hence PEC is not possible.
The solution is to guide probably with a stand alone guider like the lacerta mgen.
Or stick to under 2 minutes at 200mm.

Re: Skywatcher star adventurer
Did some more data capture. It has a 144-tooth worm. Fundamental periodic error is about 28" to 30" p-p.
I DIY'ed a counterweight shaft. No change in performance. Guided performance is about 2" RMS.
