Here is the place to talk about all those equipment(Telescope, Mounts, Eyepieces, etc...) you have. Not sure which scope/eyepiece is best for you? Trash it out here!

Is this mount gear quality same as Atlas EQ?

it's pretty much the same. do note that you can get a used Atlas for under $1000 USD ( = $1200 SGD). Figure another $500 SGD (tops) to have it shipped, = $1700 SGD + GST.

that should give you an idea of how much a resale unit here should cost..

This time I will try sirius EQ-G mount as it is lighter then atlas. I don't want carry too much weight. If it is too much for me then I have to go back to use my GP2 mount again ha ha.

If I have the GP2 with the HAL-130 legs, I would just get proper motors for it and use it instead of looking at HEQ-5.

I just got my EQ-G mount but it's not the mount that can be easily transport to the remote without any trolley. Probably have to find an easy folding trolley which have Soft Wheel. Anyone have any ideas on transporting trolly for such mount?
Thanks.

I'd also be interested in such a trolley... if it exists.

Hi,


EQ- mount Polar alignment takes long time to do.
I don’t have any place to fix the mount permanently, looking for
Other option to place the mount at the same place each time visits.
It should require to do little bit of polar adjustment.

Any ideas?

Thanks.

With practise, you should be able to perform drift polar align within 30min.

Have a nice day.

I am using the payware WCS-DSI, which is specific to the Meade DSI camera. There also is a version for ordinary web cams.

By drift-aligning through my 900mm FL scope, I can get a polar alignment accurate enough for 7-8 minutes unguided.

And (contrary to its instructions) it is possible to drift-align on just about any star, or even one of Jupiter's moons. You just have to pick a target close to the celestial equator (which Jupiter is). This enables really fast azimuth alignment.

For aligning in altitude, a star close to the pole is better, but even a star close to the equator will show drift if you wait long enough. And at a long focal length, it won't be a long wait.

Generally if the initial polar alignment isn't too bad, I can get the azimuth zero'ed in with 3-4 iterations of WCS-DSI which is about 15 minutes. Ditto for the altitude. So... yeah, 30 minutes still.

WOW! That's very long for 900mm FL unguided... are you using a GOTO mount?

Have a nice day.

Nah. But he is using an Astro-Physics mount :)
