i havent had a chance to check out the AN yet because of the weather but i have done an encoder/mechanical test and all seems fine so far.

i cant wait to check it out but im interested to know if anyone else has had a similar problem and im not sure what i can do to fix it other than either raise the height of the ota or lower the encoder somehow, ill post some photos if i get a chance tomorrow

Got my AN on Wednesday. All ready to go, not a star since due to the weather. Gave me plenty of time to set things up properly. Photos at;

I have upgraded from a Dave Ek Box with PalmDSC. I decided against a AN about 4 years ago and bought a StellarVue Refractor. Sold the StellarVue Refractor last week and bought a Argo Navis.

All the best with your AN.

Hi Paul,

Your install looks really good.

Hope the weather clears for you soon.

Thanks Gary,

I could have done with another 100mm on the main encoder cable to the AZ encoder Eg 1.3 and 1.4

I can live with it for the moment but, I didn't factor in the rotating tube.

Thanks for those photos Paul, they are very sharp and really show exactly what's going on. You must consider that I have never actually seen an AN outside of Gary's website and via photographs, so your shots were very interesting to me indeed

No worries,

I have done some more work on the scope, tiding the cables and permanently wiring a 12V DC battery connector into the scope.

I'll post those to the website shortly.

I have done everything but point the AN at a star. We've got the weather that Sydney had at the beginning of the week.

Mate, how can you stand it? It must be driving you crazy to have everything in place and no chance to use it, I feel for you Paul

Nice! Looks very ergonomic at eyepiece view. Classy looking scope, too.

if you need another 10cm length, you can cut and re-splice regular ol' telephone cable to get yourself some extra length for that encoder...

Paitence. The only thing for a situation like this. The forecast is lousy for the next couple of days as well.

I've taken the opportunity to remove the primary mirror cell and I am going to install some set screws (ones that can be undone with an Allen Hex Key) for the mirror clips. In that way I can remove the primary mirror without removing the whole cell.

Cheers Scott.

A lot of help but all made here.

One thing you cannot see is that the sides of the rocker are three pieces of Marine grade ply with a beautiful grain. The two outside pieces are 6mm the middle is 12mm, but have 10 large circles routed out of them. This cut down the weight of the rocker by about 3.5 Kg. By placing the 6mm Ply on the sides you would never know. Unfortunately, I actually never photographed the sides while they were being made.
