Hmm, I wonder... (150PDS on Astrotrac!)


Recommended Posts

Just for kicks, I thought I'd try this:

That's a 150PDS on there!  The AT drives it without breaking a sweat, it could do with a smidge more counterweight, especially once I hang a DSLR on there, but a 130PDS just might be perfect....

Am I mad?!

Not many probably know this, but this complete AstroTrac setup has the same Load Capacity as the Advanced VX and HEQ5 Pro (15kg for visual).

Tho you would ofcourse need some extra counterweight when putting a 10kg OTA on it. That speaks for itself. :)

the th3010 head only has a 10kg capacity hasn't it?

and it does of course cost 2 or 3 times as much as the heq5 :)

The Complete "Travel" package the OP has (Mount + head + pier), has an advertised load capacity of 15kg.

Yeah, I saw that...It really doesn't make sense to me though as the same head also advertised on flo is only rated at 10 kg...not sure how a pier can "beef up" the head. surely a chain is only as strong as it's weakest link?

The head is designed to take a 10kg unbalanced load i.e. a camera and heavy lens on a ball head joint, the extra capacity is due to the counterweight system.

This. You don't get the counterweight system when buying just the head. Hence the lower advertised load capacity.

Still very impressive it can handle up to 10kg unbalanced tho.

yes you do

Hmm... then you would expect an advertised 15kg load capacity.

EDIT: Here on TS is the official description of the TT320XAG set and there it says 15kg load capacity.

Yeah, I know the astrotrac is rated at 15kg, but the head (TH3010) is only rated at 10 kg

It really doesn't matter really as I caan't imagine there'd be too many people hanging 15kg off their astrotrac. I love mine already and I've only had it a few weeks. the most I'll put on it though is my 60mm apo...anything bigger and I'll use the neq6. At the end of the day, numbers don't really matter, it's results that count and if you get results with 50kg on it then I'm not going to say it's wrong to do so :)

Absolutely! Love the design of the AstroTrac tho. It's as portable as it gets. Tho the upcoming Skywatcher offering will throw some competition in the mix.

That could be very interesting for camera + lens pics.  I'd love to know it's capacity, but I'm guessing it'll be stealing sales of the Vixen Polarie and the iOptron Sky Tracker at that price.

Me too having the load effectively at the center of the bearing gives it a large capacity for a small overall weight and not many mounts can do 15min subs unguided.

I think ive seen pics with a scope so its head to head with the astrotrac.

Looks fine to me except for when the wind picks up. On a calm night it should be okay but I wouldn't expect very long unguided subs, 60 seconds should be achievable, a bit more at a push.

My lens and camera combination balances just right with the large and small counterweights at their furthest, which weigh about the same as your OTA on its own.

Be careful if ordering another counterweight, I did and it didn't fit on the bar properly (by fractions of a mm), they wanted me to send my existing counterweight bar and counterweights to match them all up...

To be honest, I wasn't really that serious about it - but I am tempted to order up and try the smaller 130PDS.  Still might be a bit of a challenge unguided, but I could drift align.

I've seen pics with a frac mounted on the sw but to be honest, the 5kg max load is a bit off putting although it does come in way under the astrotrac...I'm not swapping though :)
