Hi, I am looking at my first mount.

I have narrowed down the list to these three options that are in the same range

- iOptron EQ30pro, 15kg payload,
- Skywatcher Heq5 pro 15kg payload
- Orion Sirius 13.5 payload

Recommendations?

I want to control the mount from PC, including guiding from PHD via ASCOM. I understand with skywatcher I need a special cable for EqMod, not sure about Orion and iOptron.

iOptron has some extra features (like GPS) but I's also the most expensive.
What about gear/motors and tracking performance?

Thanks

The iOptron models are the ones I know the best so I would opt for this one on your list.

 

iOptron iEQ30 Pro Equatorial Mount

Includes Tripod with 2" Diameter Legs & Hard Case  $1398.00

However here is a discussion about the HEQ5 vs the NEQ6 which will give you more information on the HEQ5 Pro

 

https://astrobackyar...m/heq5-vs-neq6/

 

Consider that the iEQ30 and the HEQ5  are actually almost the same price when both have the GPS.

 

Also consider that the EQ6-R Pro is only just a little over $220 more with GPS added and is a much more substantial mount.

 

I know nothing about the Orion Sirius so I can't comment on it compared with the others.

 

There's a saying here on CN and it's " Always go with the best mount you can, even at the expense of the ota."

These are all closely comparable.  Performance likely varies more with individual samples, than across mounts.

 

You'll need a cable/adaptor for the iOptron,   "RS232-RJ9 cable" is included, but you also need this, unless your computer has an RS232 port (unlikely).

GPS is mostly needed for polar alignment, a PoleMaster will do that better/faster/easier.

 

I buy iOptron because the old man needs the light weight.  <smile>

The Sirius and the HEQ5 Pro are pretty much the same mount. I would take either over the iOptron simply because of a very long history of excellent performance with those mounts.

 

GPS is only an advantage if you don't own a smartphone *and* have no internet connection when imaging *and* forget to look up your intended site in advance. Not much of a reason to buy something.

 

Don't expect to use 15kg loads for imaging without performance degradation. Marketing and reality are different things.

Thanks for reply


I will use a polemaster, so I understand GPS is not essential.

Both heq5 pro and eq30 pro can be controlled via ASCOM from PC and PHD2, correct?

I once red somewhere that the Sirius is lacking of the most modern connection, not sure about it.

Yes they can.

Skywatcher HEQ5 = Orion Sirius

The Sirius can do ASCOM.  You also may need the right cable for it.

The 30Pro may be a bit easier to set up, could be I'm just used to iOptron.

 

I mildly disagree with Stelios, the 30Pro, the second generation of the 30 series, is a well sorted mount, a solid performer for that price class.
