Celestron Advanced Mount GoTo - CAM

Hi All

I've been looking around - again! - on how to solve my imaging problem (used EQ5 with GotoStar controller_motors) and 8" newt.
The tube weight incl. all other accessories (dove tail bar, tings, finder, etc..) weighs 9kg and the mount just can't deal with this.

I've found the Celestron Advanced Mount GoTo - CAM which would cost 1400 NZ$ new, incl shipment and NZ GST.
Max weight listed is 12kg.

There's a review with photos, some are 150secs exposures, unguided.
AND they were taken with a tube that weighs 9.4kg all on its own.
(The ice on the tube is shocking, though...)

Is anybody here using this mount for imaging?

I just need a few voices to strengthen my resolve

Hi Silv. This is the CG5GT (Telescope Services gave it the "CAM" name), which is basically a somewhat upgraded version of the EQ5 that you already have. Biggest problem is likely to be the 10kg weight capacity, which means that it will be marginal for imaging with all but the lightest scopes. http://telescope-service.com/Celestr.../CAM_GoTo.html

Can you get the HEQ5pro at a reasonable price in NZ?

"somewhat upgraded", yes. in my newer link to the product, the load is stated as 12kg. (possibly due to 2" tripod legs?)
I noticed that TS-express overall gives cautious statements re load.

but a major thing might also be:
the customer with the C9 didn't have such a long tube like mine.
AND on mine, the main weight is at the top.
his tube's main weight was right over the mount head.
I don't know if that's true. But it feels wobbly just thinking of it.

ah, bummer. thank you for bursting my bubble, Shiraz.

No, the HEQ5Pro comes at 2000 NZD and more.

There's a used iOptron Mini Tower (first model) on trademe for $ 1.150.
Alt/Az mounting exposure time would be much longer than what I can do now. But again, my tube is probably too heavy and also too long.

I was almost buying the HEQ5 here on the classifieds. Flying to Melbourne and back same day. But in the end, there'd be no $ gain.

My driveway in the ditch, surrounded by slight hills and to the west and s/w by trees adds to the problem with my current EQ5.
I was lucky to find the Lagoon nebula at the Zenith. But exposure time was reduced to 3.2 seconds, still elongated stars. Frustrating.
The targets which allowed for 8 seconds 4 weeks ago, Derwish, omega centauri, carina etc are now hidden by the south western trees.

There's only so much drift alignment you want to practice when you are under the stars...

Oh, and even if I wanted to do visual observing, which doesn't appeal to me atm, I'd have to buy better eye pieces.

I can only go back to piggy back. or give up.

Good luck with your search Silv , something will come up I am sure .
I also recon that a HEQ5 is minimum for what you want .
The CG5GT is a good mount , as a mate up here has one under his C11 , its ok for visual but way to small for AP , but he is a totally visual observer so it works well for him ..
One thing do you really need a GOTO mount ? there is a standard HEQ5 for sale on Trade Me in Christchurch for $1200 at the moment ? a thought .
Hope it all works out mate .
Brian.

Don't give up - you'll get there.

ah, bummer. thank you for bursting my bubble, Shiraz.
sorry Silv

Your current EQ5 mount should give you much longer than 3 seconds. Did you try adjusting the worms to get rid of backlash? - could improve things a fair bit. Is there any way that you could get someone with mechanical experience to look at it and see if anything is obviously out of kilter? - your problems seem much worse than they should be and it is possible that something fixable is at the bottom of this.

thanks for inflating my bubble, Shiraz
I was grateful for you bursting it, too.

no, did not take it apart.
took it to Andrew from the Observatory here in Auckland but that's not his expertise, he said.
Don't know any other people here and somehow I doubt the two pigs in the paddock can help.

cute though.
I'll attach Sophie when she asked me for a dance, yesterday.

"something fixable" - why does it make me feel tired to read these words?
uhm. okay. will try and have a look. Shiraz, thanks!

Goto: not a must, no. hmm.
I did find Lagoon in the camera eventually. And that was pretty much without the GoTo function - the slewing up there was too far from target.
Goto and tracking are much much much better in the eastern lower altitudes where Auckland's city glow is. I probably have an EQ5 version afraid of the dark.

A new thought. Cheers mate!

The funny thing:
In April, I had ordered an HEQ5 Goto from ChCh but got delivered a non GoTo. And was told: "that's what you get in NZ when you order a HEQ5 Goto." Which made me furious! I suspected all sorts of criminal salesmanship. Hell hath no fury ... It must have been a misunderstanding on his side.

Would be funny to buy that now on trademe. Could be the exact same device I already had in April. Did he finally give up pretending it is the more expensive GoTo? (No, just kidding.)

any thoughts on this? Trademe: Meade LX200 10" f/10 for $2000

I checked the HEQ5 on trademe: the seller states 10-12kg max. load.
dunno if it has a different tripod than the white model or what takes 3kg off the load capacity.

read this first http://www.danlessmann.com/Articles/AstroMistakes.htm

my HEQ5pro will just track well enough for imaging at 11kg - less would be better. And forget it if the wind is blowing and you have anything like that load. However, it can work OK sometimes and it is almost certainly the lowest cost mount that could be considered capable of serious imaging of DSOs. If you go that path, would strongly advise that you get one with GOTO or you will have to go down another rabbit warren trying to find out how to make it guide later on - the Synscan mount connects directly to an industry standard guider and just works.

there's a QHY5 on trademe for 400

enjoyed the read!
fork Alt/Az mount: no astrophotography - in Ohio.

I should try to sell the EQ5 and buy a new HEQ5 Goto as was my original decision in April.

Wrong!
Probably something will still bug me. But that wouldn't be the mount. then.

pheew.

How would I describe the mount in Trademe?
That's a serious question.

Silv-$400.00 for a QHY5 seems way too much-talk to Theo at Gama Electronics

Thank you! Will keep that in mind.
I was merely illustrating how side tracked I can become.
an offer for red high heels for 20$ would have been more obvious. sorry.

Yes, how about it?
It's been on the market for 5 months, now.
Surely, all bugs will be ironed out by now?
And you'll be "ready to get way out there where those dim fuzzies live, right? "
Yeah right.

I like the blue.

The LX80 Meade dual mount was due to be released in Jan 2012. I spoke to Bintel about it the other day and all they could say was they had no idea about a timeframe.

It is vapour ware at this stage.

I was thinking about saving my pennies too for the LX80 but I've seen some very long posts on other forums about all sorts of problems with this new mount, in particular in EQ configuration. It seems it can't really handle the stated loads, more like about half and even then as an EQ imaging platform it still seems to be unstable for clean long exposures. It appears Meade have skipped a bit on the quality control, making some parts thinner than they should be and using plastic gears instead of metal so early adopters seem to be beta testers for meade to iron out the bugs. In altaz configuration it seems to be very good though. I'd avoid jumping on the LX80 (unless you are made of cash, in which case feel free to buy me one too , wait for it to reach our market and be out in use for a while and see if it lives up to its spec list.

Maybe a meade tube on an eq6 would be a better combo.

the NZ telescope online shop sells it, now.

Shiraz linked an article above about how to successfully waste money.
accidentally, it starts with a Maede product, new to the market, too.
and in it's wake, another new Maede product floats up.... both bad choices for the author.

Fun read. Rhetorically worthwhile, too. The repetition of

"ready to get way out there where those dim fuzzies live, right?

Wrong
!"

really sticks.

New products do need time to mature.

about the lx80, i rung bintel yesterday to ask about it. he told me the same thing about the payload. recons the biggest it can handel is an 8inch sct and a fat refractor. what happenned to the other 75 pounds(34kg) in dual scope mode. the eq problems are software related apparently and the ones they have recieved are supposed to be the new updated software.
such a bummer because the 34kg payload may have taken my big dob at 20kg and a big fat tracker. oh well back to my home made motorized base then. boho.
