Hello, everyone!

At the moment I am looking into finally buying my first real equatorial mount.

To date I have always relied on my star adventurer v1 which has allowed me to approach the astrophotographic world without having to spend an enormous amount of money.

I also recently bought my first refractor a Sky Watcher Evostar 72ED (420mm-72mm) and replaced my mirrorless with an astromodified dslr.

I am realising, however, that I have reached the physical limit of the star adventurer, both in terms of weight and tracking accuracy. In fact, it only takes a minimum to lose polar alignment and no longer be able to track for more than 2 minutes. 

(Side note: against all odds, I managed to track for over 3 minutes without autoguiding at over 400mm focal length. Provided, however, excellent polar alignment with sharpcap and perfect balancing of the ota)

Getting to the point: I had my eye on the heq5 which seems a fantastic compromise in terms of stability and weight of the mount. The problem is that it is really difficult to find used ones and they cost far too much (~1200 euros) when new. In terms of performance, from what I understand, it would really be perfect: with the range it has, it would allow me to have plenty of margin with my current equipment and would allow me in the future to approach a medium focal length (~700mm), perhaps with a small newton.

To overcome the above problems I was also considering a downgrade to a normal eq5 synscan or even an eqm35 pro.

Are the latter two so much inferior to a heq5? In your opinion does it make sense to buy them or should I hold out and go straight for a heq5?

Do you notice any real differences in everyday use, or is it just a matter of stability?


Thank you very much and clear skies!!!

I have both mounts and I love my EQM35, very easy to polar align, works very well and i really have no issues with it, its also very light which makes it great for travel which i do as i can not image from where i live. 

The HEQ 5 is a beefier mount which can handle more weight. i believe 30lbs as opposed to 22 for the EQM. Its still light enough to travel with as well. I have no issues with this mount as well however polar alignment can be challenging as the polar scope illuminator is extremely bright so i like to align while there is still some residual light out there. But there are ways around that. Installing the EQM MOD software has a dimmer which helps with this issue.

I would go with the HEQ5 as it could handle more weight and i think tracking would be better with this mount. Check the website Cloudy Nights and you may be able to find a used one within your price range.

I am happy you are in the upgrade frame of mind. I have used the Orion Sirius/heq5 mounting for 20 years ( I have owned 3 over that time). I would get one, use it, love it and because I always had a nice scope on them, ended up trading them with other folks over the years. Of course, after I would make the trade, I would immediately regret the decision and get another Sirius. I also own the same OTA you have. The Sirius/heq5 and the 72 would be awesome. The EQDirect cable and Green Swamp ASCOM server (EQMOD alternative) opens the door to a very easy AP solution of your choice. I have a pic of my Sirius/Samyang 135 rig on my page… If you would like a picture of my 72 on the Sirius/heq5 for what your system would look like let me know.

If you like to tinker to save money. Maybe you can find an older mounting that is out of action (Bad motherboard, motor, etc) and DIY a drive system with the OneStep (i think that is the name) system. Your problem is, that everyone who has one, does not want to get rid of it or they have 6 people they know who want it when they do and they rarely make it to the boards for sale. Maybe you might have better luck finding someone who wants to sell the entire rig as a package regardless if you are interested in the OTA

I hope my testimonial aids you on your new mount quest.

Cheers and CS, Tim

I have also noticed the fact that it is very difficult to find any around....

I had also thought about finding one out of use but even there it's not so easy!

Thank you for your helpful reply and cs!

Having owned the EQM35 i can safely say that this is absolutely not a product you should be even considering, it is an EQ3 with extra marketing behind it to make it appear like a competitor to the EQ5. In fact the insides of the EQM35 are very similar to the EQ3 in the sense that it does not have bearings in the RA and DEC axis, but is instead supported by plastic washers, cheap lubricant, and not much else so any hope of achieving good and reliable guiding with anything but the smallest scopes is lost. The EQ5 is only slightly more expensive, but actually has bearing supported axis and so has a chance to work well where as the EQM35 has a guarantee of never performing well.

Get the HEQ5 to stay on the safe side. If you absolutely have to save money on this (recommend not), then get the EQ5 as it is a superior mount to the EQM35 in every measurable way.

Hi, thank you very much for your contribution. 

It is good to hear that the lower range of the heq5 is also good.

I'll see what I can find around.

Thanks again and CS!

I thank you for the opinion.

It is interesting to see how on the same mount (eq35) opinions are so conflicting: those who love it and those who hate it... I'd be curious if indeed, being entry level mounts, they actually have a different build quality for each production batch?

It seems that the opinion is clear: if I can raise the money, the heq5 is worth it. 

Thanks a lot to everyone and CS!

I imagine the EQ3 and 35 are quite cheaply manufactured so there is a high chance of receiving a "monday morning" unit from the production line. I disassembled mine to try and find something to improve and was not impressed at all of what i found. The complete lack of bearings and plastic washers shocked me the most, but i also found some metal particulates in the lubricant, and the lubricant was not very high quality anyway and was either applied too much or too little in my unit (the mount barely worked in Finnish winter temperatures of down to -27c). Cleaning the innards and applying a better grease (Superlube) improved performance just a little bit, but its no magic trick to make it a precision mount.

One mount not mentioned is the Celestron AVX mounting. I have owned one in the past. I don't like it quite as good as the heq5/Sirius because of not using EQMOD or Green Swamp. I also am not a fan of external motor cables. It does interface with CPWI software and can be computer controlled. A solid mount, mine tracked well and is similar in capacity and form factor to the Sirius/heq5 and is in your price range.  Just a thought.

I use the EQM-35 and find that is works great with 8-10 lb. of equipment.
The HEQ5 is obviously a better mount but the EQM-35 is light, easy to carry around and I do 10 minute subs with it all the time.
If you can find one in your price range I would get one.
I paid $700 for mine  (I think they are $999 now).
I have used it for 2 years with zero problems. I also have the EQ6 which is Superior of course that I use for heavier scopes, but
I use the williams 71 gt and the Williams z81 with 2600mc cameras on the EQM-35 easily.

It must be said that the -27 degrees certainly did not help to enhance the eventual qualities of the mount

Anyway, thanks again for the tip, I am more and more convinced to go in the direction of the HEQ5...

The price is almost identical to that of a heq5... I have an idea, however, that the Sky Watcher is more for me. What do you think?

Thanks!
