Recommended Posts

Hi, 

I was wondering how much can an EQ-2 mount carry because have found a good telescope and i wieghts 4.54Kg but i am wondering if my mount can hold that much weight,

If you can achieve balance, it will be fine, you don't have any motors to burn out. Getting balance may be the problem and you may need to do some DIY counterbalance work. But yes, just get the scope.

It might also depend upon the size of the telescope. Something small and compact such as a mct might be ok but a longer telescope might act as a sail and wobble in a slight breeze.

No load capacity for the EQ-2 is quoted, but the load capacity for the more substantial EQ3-2 is given as 5Kg.  So you figure it out...  It appears that a telescope weighting 4.54Kg will be at best on the limit for the Eq-2.  The practical result will depend to some degree on whether the telescope is long (traditional refractor) or compact (Maksutov). In any case, for a "good telescope" you might consider a mount upgrade worthwhile.

By any chance is that a Celestron C6 you are looking to buy?  The C6 tube weighs 4.54kg...  We have the C6 XLT and use it mainly on the HEQ5 or ZA4 but occasionally on the dual drive EQ3/2. Because the Celestron is so short and stubby it actually works okay on the EQ3/2. Takes a few secs to settle down but useable. Imaging would be out of the question but visual okay. I use this as a lightweight setup to take down to my nephew and niece. Saves lugging the HEQ5.

Because the counterweight bar is long on the EQ3/2 we have had absolutely no problem balancing the C6 using the two supplied weights.

The tube length is critical as well as it's weight.

A light but long scope will overpower a mount even if it is well within the load limit.

For a while Celestron used to supply the C5 SCT on the EQ-2 mount as an option.

If it is the C6 OTA that is contemplated, it looks that you can get it with a Astro-fi mount or SLT mount for the same price.  If that's correct, you are getting a free (but wobbly) GoTo mount worth around £250.

I used to mount my 're-modded' ETX105 or C6/SCT-XLT on a small EQ mount; then sold it. It was OK, but I would not overload it.

Then came along the Vixen GP; (which I have also sold); which was about twice the size, just over twice the weight. Better in terms of build quality, reduced vibrations, etc., I could also mount both 'scopes side-by-side', (though balancing is critical for smooth manual operation); and not possible with the smaller EQ.

I now use an AOK-AYO or Tele-Optic Giro alt-az mount as shown below...

      Hi all, 
      I have what might be a silly question regarding alignment of the start adventurer:
      Are you able to align the mount without being in sight of Polaris? 
      I'm weighing up my mount options and was curious if this is possible. Most of my AP will be done from my balcony and unfortunately the North star isn't visible at all from this point. 
      S.

      FLO sent me this beast of a mount for review, and after a few months use I've finished said review. If you don't want to read, then scroll to the bottom to see the video. If not, let's go.
      From the top, the dual type Vixen/Losemandy type puck, and at the back of mine it had 3 5521 type power ports for powering equipment, and 3 USB ports (2 powered) for connecting to the internal USB hub network. Whilst I didn't exactly use this network, it's still very handy to use, especially being on the puck - it means you don't have to worry about any slack on your cables and they won't pull. A handy feature. The power ports seem to be of a different type to 99% other astronomy hardware though, which means you'd need to get different connectors, a major inconvenience which still will make itself known later.
      The mount includes an iPolar system, which is absolutely awesome. Sure the UI looks like it's straight out of Microsoft Paint but it's certainly function over form as it's quick and uses plate solving to align. This means you can polar align even with a semi-obstructed view to the pole. It's powered by a USB2-B port at the back of the mount with no need for external power. There is no manual polar scope on the mount so a computer is a must for polar alignment.
      The carry capacity of 31.8kg is a hefty amount, though it's advised to not exceed 21kg for astrophotography. I never loaded it up with this much equipment however the sheer build quality and performance of this mount leads me to have no concerns whatsoever about using that much weight, or even all the weight. It's always advised to use underneath the stated maximum capacity anyway.
      The altitude adjustment knob is a hefty coarse worm gear style affair. Embossed with the iOptron logo. It's a nice way of adjusting, especially when coming from GEM mounts where you have to undo/do up two individual bolts. However on my mount it was let down by an abhorrent squeak it made when raising it whilst the mount was loaded up. When going down in altitude sometimes the gear would jump a bit and let the mount down even further than I wanted. Azimuth adjustment was fluid and great.
      The control panel includes its power port, power switch, hand controller port, ST-4 port and the USB port. The USB port can be used to control the mount via computers, and is also the other end of the internal USB network. It is USB2-B. 
      A major issue I found was the power port. It wasn't the standard type DC centre-positive tip style that all my other astro equipment used. IT's also a standard female type port, whereas I would've liked to have seen a screw type connector for this price point. But yes, the biggest gripe was the different style port, which meant I couldn't power it using my power box (without getting more cables), and had to use the supplied plug.
      The carry case is a substantial and very sturdy box. It's foam cutout and very tight in holding the equipment. All but the counterweight goes into this box and I believe it could really survive quite a harsh fall. It's very well built.
      Slewing with the CEM70 was quick and fluid, it was also quieter than I was anticipating for such a large bit of machinery. Using its own dedicated software through the laptop was intuitive and there was little to no learning curve. The axis clutches, whilst using a small switch, feel solid and substantial with a nice meaty clunk when engaged. One lock position is the EQ Home position which makes life a lot easier.
      When guiding, I was regularly getting values of 0.4-0.6" total error. This enabled me to take extremely long exposures if I so desired, though I mainly did  5 minutes, I was able to do 10 under testing. Unguided (just sidereal tracking) I was only able to achieve 2 minutes before trailing was found with my Evostar 80ED (reduced to 510mm) and ASI 071mc Pro. Now in full admittance the mount was unbalanced as the Evostar package was too light for the mount. 
      The counterweight, if moved too high up the bar, will strike the body. So you would need to buy a lighter weight if you wanted to balance a lighter load on the CEM70.
      Also when attaching it to a tripod or a tri-pier, you do need to bolt down 2 spring loaded bolts down with the supplied allen key. Now this is a bit fiddly and adds several minutes to the setup and tear down times. Though I suspect iOptron made this mount with a permanent setup in mind so if you're putting this into an observatory then this won't be a problem. For me, who setup and torn down the rig each night when using it, became a bit of a chore.
      Overall I found the CEM70 to be an extremely capable mount with a lot of features. Whilst there are niggles that detracted from the user experience; the altitude gear squeak and the non standard power ports. Other features improved the quality of life and user experience enough to vastly outweigh the drawbacks. The iPolar system is particularly capable and excellent, the carry capacity, build quality also and guided performance, as well as the internal USB hub. 
      I think this would be a nice investment if you were looking to mount larger scopes on, or decking out an observatory. I can't afford one but if I was making my own permanent setup I would severely consider buying one.

      Anyone have any idea where I can get a replacement counterweight bar/shaft for my EQ5 mount? 
    • By xvariablestarx
      I recently moved back to Ireland, having been in the USA a long time, and I had to leave my 8 inch Dob behind. What i did bring was two OTA, a 80 mm Orion Goscope refractor, and an Explore Scientific  100mm Mak. Now i do has a basic alt az mount for these but i have a longing for a very basic GoTo system like the iOptron cube-e. Would that work ok?
       
      P.S. sorry if this shouldnt be a beginner question

      Hello all. Thank you for taking a moment to read this & offer your suggestions/ advice. I'm sure my basic question has been asked many times: "In your opinion or experience, what are the first, most important, necessary accessories I should add in order to maximize the the use and ease of a newly acquired Celestron Nexstar 127 SLT ? I have a power supply adapter, 9mm,10mm, 25mm eyepieces, 2x Barlow and 90 degree diagonal mirror adaptor. With a modest budget and a 2 week deadline, I've researched numerous reviews and narrowed some choices to additional Plossl eyepieces, an assortment of filters or a dew shield. All of and these can probably be purchased within my budget but I'm even willing to take the plunge on an upgrade to a better mount, which I have no idea where to start. Any and all suggestions, advice and opinions are gladly appreciated. Thank you all, from across the pond in northeastern US.
