Why SuperCharge your Star Adventurer ?

 

The Star Adventurer is probably one of the most popular portable 'tracker' mounts in existence. But like many of the Sky-watcher mounts we have found more performance! Mostly wide-field astrophotography is done unguided with these type of travel mounts, often with shorter lens focal lengths of less than 300mm and rarely more than 2 minutes per exposure.

 

We applied our build methodologies from our successfully accurate hypertuned mounts, and played with the Star Adventurer, pushing it as far as we could during summer testing. The standard mount has been tested in guiding from 2-4 arcseconds, and between 23-50 arcseconds by owners, from our research.

 

Tests have been carried out on the Star Adventurer but only on lighter payloads, but it can take an 5Kg+3Kg payload, so why can't you make the most of it?

 

The stock 1kg counterweight is fine for most setups, but with our exclusive BoDai CloverThree counterweight, three full 330ml cans take it to 1.2kg, with a max of 1.6kg, filled with sand or dirt. This means you can balance a 72mm refractor telescope, flattener reducer, DSLR Camera body AND a 50mm finder on this mount and reliably get under 2 arcseconds guided for over 2 hours (in tests) at a time, with Zero Dropped Frames!

The result is a stable mount that tracks at circa 1.6 arc-second (tested 4.5kg) or less (depending on payload and balance) guided and 10-12 arc-seconds unguided. It means that you can now run a camera body and lens at up to 500mm. OTA's under 500mm are best, unless it's a small 102mm (or less) Maksutov.

 

That's the whole point of tuning your mount. It's about not losing 30-40% of your effort in lost data. Over a four hour chilly evening, would you really want to lose over an hours worth of imaging every time?

All of these mounts are optimised, not some part of a production build where a median set of tolerances are used for productivity.

What do we do to make your Star Adventurer perform better?

Your existing mount casing is very carefully taken apart as there are several fragile wires. The RA axis is stripped down, ultrasonically cleaned and re-lubricated, to remove stiction, as is the front clutch plate and needle roller bearing. The motor block is checked and re-adjusted and the worm-gear bearings which are replaced with lower friction items, that we run-in ourselves that have the benefits of being longer lasting, smoother running and more responsive than standard bearings to provide better tracking.

We also remove the right amount of backlash from the final drive cogs, re-grease and reassemble the case.  It's fiddly, but worth the effort. You're welcome to try, but a third of our work by the way, is repairing 'home tuned' EQ mounts that didn't turn out well... The devil is in the detail. We use three types of lubricant in this build, which also improves the feel of the main clutch, and reduces the drag of the photo kit making it easier to balance. We load test with a small refractor, and check and adjust the RA to eliminate any residual backlash as part of our meticulous build. It's even more important to be careful with such a small mount to check, check, check your tolerances.

 

Below is a cropped single 10 minute (602 seconds to be precise) or our Star Adventurer with a 200mm EF lens (=320mm focal length  due to crop factor) on an APS-C Canon EOS450D. We have a stack of these and 5-8 minute ones, and will be adding other examples as we continue our development.

 

PHD graphs and more info is available upon request, as testing is always ongoing with all our mounts as part of our quality control. All our work on supercharged Star Adventurer mounts is guaranteed for 1 year.
