  1. Have scanned the instructions for the mount. Images are at the bottom. Rowan AZ100 Alt-Az Mount Please read all instructions before using your AZ100 mount. The AZ100 is very rugged , however, like any precision instrument it can be damaged by improper handling. Please refer to the diagram below for an illustration of the mount. Mounting capacity. The AZ100 has a capacity of 15-20kg per side depending on the lengths of the telescopes in use.Generally it is recommended to mount the heavier of the 2 scopes on the left side of the mount in the saddleshown. And if using one telescope attach this also on the left side of the mount as the left side is designed tohave a slightly higher capacity than the right.If using a counterweight shaft attach this on the right side of the mount in the central M16 hole of the saddle orusing the counterweight mounting flange. Azimuth and Altitude Clutches. The clutches are fully adjustable and can be set over a wide range to give the required amount of friction to theaxis. Altitude Lock Gently tighten to hold the telescope in position while there is an imbalance whern changing eyepieces. Azimuth and Altitude Damping Adijusters. Each axis has a pair of damping adjusters. These allow additional friction to the slow-motion controls only to ailow a smoother movement with large or long telescopes. Set them with approximately the same tension. Worm Adjustments Worm mesh adjustment may be necessary from time to time. The adjustment is straightforward and the user should not be hesitant to attempt this and in doing so will achieve thebest performance from the AZ100 mount Before adjusting the worm mesh check the balance of the telescope is as close to balanced as possible with the eyepiece and finder fitted. The worm mesh can be set by adjusting the worm mesh screws (A) and opposing grub screws (B) at the opposite end of the to the slow-motion control shaft. The worm block screws (C) should remain tightened (Approx. 2Nm torque setting) Start with the worm mesh screws (A) and opposing grub screws (B) loosened off. The slow motion shaft should turn freely with virtually no resistance. You may also feel a small amount of free backlash in the axis. Make very small inward adjustments to both worm gear mesh screws (A) and at the same time slowly rotate the slow-motion controls to feel when the resistance changes. Once a very small amount of additional resistance can be felt on the slow motion control , this is the point where the worm is just coming into contact with the wheel gear and the mesh is now initially set. Gently tighten the opposing grub screws (B) in to contact to lock the worm block into position. Further small adjustments can be made depending on the user’s preferences and telescope configuration. Cleaning When required wipe over with a clean cloth, preferably microfibre. Don’t use strong chemical cleaning solutions. Maintenance It is advisable to re-grease the worm wheel gearing every 12-24 months depending on use and environmental conditions. We recommend an Areoshel 33 or compatible grease. Remove the telescope from the mounting. Warning - if the worm block is removed whilst a telescope is mounted the axis will be free to turn uncontrollably. Remove the 4 x M4 cap screws from the worm block and lift away from the axis body. Clean the old grease away from both the worm and wheel gear. A tooth brush is ideal for this. Once clean re-grease the wheel with Aeroshel 33 or similar with with sufficient grease to to fill the gap in each of teeth on the wheel gear. Apply a thin coating to the central section of the worm too. Replace the worm block taking care to engage the worm to the wheel teeth then replace the 4 x 4mm x 12mm cap screws into the worm block. Do not tighten these until until you are sure the worm is properly meshed into the wheel gear.Re-set the worm mesh as per the procedure above.
  2. Rubbish here as well for the last few days but there is hope for Monday though. Want to give the AZ100 it’s first outing.
  3. Second the power supply being the likely culprit. Are you using a battery or an AC adapter?
  4. Question came up on my CN thread but perhaps Rowan will let us know. Perhaps some sort of micro adjuster plate to fit in between the saddle and mount?
  5. A question for John or Stu. When using two scopes on the mount have you found a way to fine tune alignment of both scopes so they are both pointing exactly the same?
  6. Forecast for Sun is maybe and good for Monday.
  7. Mount fits perfectly to the EQ5 Berlebach tripod although had to make up an adapter and thread the tripod to take an M12 bolt to allow fitting an EQ6 mount. Can’t understand why Berlebach doesnt offer an adapter or just produce a dual fit one. Can be changed from EQ5 to EQ6 in about a minute without using any tools.
  8. And more with Big Red mounted. Been searching for a mount worthy of Big Red for years. Can’t beleive it’s been nine years since I built Big Red.
  9. Load of better photos taken outside in proper light.
  10. It balances easily with the alt clutch only partly tightened. With the AZ100 you have the alt clutch knob, the alt lock knob and the worm gear mesh adjustment as well so you can adjust the mount to handle a poorly balanced scope if needed. It’s been designed for real world use.
  11. Lovely night for observing..........NOT
  12. Yes it’s the luck of the draw with the stock focuser. The tolerances of the parts used in one of these cheap focusers can stack up right and it can work very well or the tolerances can stack up the wrong way and it can be beyond any adjustment or fiddling with to make it work right.
  13. Here you go. Couple of pics from the manual. https://www.baader-planetarium.com/en/downloads/dl/file/id/175/product/2858/instruction_manual_for_all_baader_diamond_steeltrack_bds.pdf
  14. Annoys me that they push scopes with rubbish lightweight EQ mounts as beginners scopes. Wonder how many have been put off astronomy after buying one?
  15. Built to a standard not a price is the way I would put it.
  16. If I hadn’t already had a spare Altair saddle would certainly have bought the Rowan one.
  17. Test fitted the 8” Classical Cassegrain. Feels so different to the TS-AZ5 (Skytee). Much more stable with no feeling like the whole thing is going to tip over without a counterweight unlike the TS-AZ5. Movement is so much smoother and find the OTA balances a bit further backwards than the TS-AZ5. Found I could back off the Alt clutch so it just kept the OTA in postion but could move the OTA manually without the slo-mo controls but the slo-mo controls still worked fine without tigtening the clutch. WOW what a mount. Thoroughly impressed even without having it outside yet.
  18. Yes it is with an EQ5 top that I converted into an EQ5 or EQ6 fitting.
  19. Thought at first it was just a box of foam chips.
  20. Hi Steve And very nice it is too. Now if only the forecast for some clear skies on Sunday is accurate.
  21. First pics. Not short of mounting holes for the saddle. I used the Altair dual fit saddle as I had one and didn’t see any sense in buying the Rowan one and the Altair matches the mount very well.
  22. 15mm Ortho ............... OK actually the long awaited Rowan AZ100 Pics being posted in the Rowan AZ100 Owners Thread
  23. A box just arrived by DPD. Wonder what’s inside.
