  1. Received all the components now. This is the "Basic Hand Controller" for my second Onstep diy Goto system. I control slews by Wifi or Bluetooth from my phone using the Onstep app or SkySafari Plus which is brilliant, but for centering objects in the eyepiece a handset with real buttons is a far better tool for frozen fingers & dark-adapted eyes. The case fitted the hardware like a glove thanks to the precision 3D printing skills of @tooth_dr to whom many thanks. Components & Links Onstep Basic Hand Controller; https://onstep.gr
  2. Thanks for your help everybody, and a special Thank You to @tooth_dr who printed the case for just the cost of materials and postage, and shipped it across the Irish Sea , all in just a few days. As you can see from the above photos he did an absolutely superb job - far superior to any commercial offering. I'm still waiting for most of the internal hardware from various vendors. I'll post a pic of the finished item as soon as possible. It is a privilege to belong to a great forum like SGL, whose members are so generous with their time and so happy to share their expertise.
  3. Do you have diy skills? You could build an equatorial tracking platform for a manual dob. Lots of guides online. Or you could build an Onstep Goto system. Examples here, including a system for a 22" dob. https://onstep.groups.io/g/main/wiki/4414 Either option would cost much less than the premium of £850 for the Skywatcher Goto, versus the manual Meade.
  4. You might want to consider the WeMos R32 with CNC V3 Shield version as well. This option, which uses the same ESP32 chip as the maxESP, has only been available for about 6 months so it is still a bit experimental & not all the optional Onstep features have been implemented yet, but if it has the features you want the build is at least as simple as the Mega2560 options but with better performance. Just plug the CNC shield into the WeMos R32, plug in a pair of LV8729 drivers, connect power & motors and you have a funtional controller that can be directed by Bluetooth from your
  5. I prefer the realistic on-screen "look" of Stellarium but if you are printing charts Cartes du Ciel is easier because. By default CdC prints black on white, so no need to copy/paste into a photo/graphics app. You can place as many eyepiece or finder circles as you like on your chart within CdC before printing. Just the job for star-hopping. https://www.ap-i.net/skychart/en/start
  6. That's great @tooth_dr, thankyou. I would prefer black and 3 or 4 weeks delivery would be fine so I'm happy to wait till you need to change filament. If that's ok please pm me a rough price estimate & your email so I can paypal you the money. Thanks again.
  7. The files are from here; https://www.thingiverse.com/thing:3017274 They have been printed before. I would be happy to take the risk of the hardware not fitting.
  8. I would like to use this handset case for my next Onstep build. Since it is designed to fit the pcb it would look so much better than a bodged, off the shelf project box. Especially with my clumsy bodging. As usual with small items the online services look good until you consider their minimum order values & expensive delivery charges. st4_bottom.stl st4_lid.stl Would any kind soul be willing to print it for me? Obviously I'm happy to pay for it. Thanks for reading.
  9. I think so. You might have to put spring washers under the bolt heads. Using inserts would allow you to use softwood for the forks. Threads tapped in softwood would wear away quickly. Or you could use longer bolts with nylock nuts.
  10. I enjoy stargazing with binoculars but even with 10 x 50's the effect of handshake can be noticeable and trying to hold them still can be stressful. So I built a parallelogram mount to use with an old "EQ3" tripod, using materials already to hand. The forks & mounting plate assembly are made from 19mm oak, from an old kitchen-cabinet door. The "horizontals" are 17 x 57mm pine. The pivots are M6 bolts. The holes in one plate of each fork are tapped M6 (using a modified M6 bolt as the tap) so the bolts are tight enough to adjust and maintain the friction and locknuts a

  12. I do most of my observing with a 200p/EQ5 but am looking to add something a bit more portable in case we are ever allowed out of our houses again. So when I found a second-hand kit including an interesting 6" scope, an old but pristine EQ3-2 mount & a broken EQ3-2 tripod, locally for very little money, I grabbed it. The tripod had none of the scuffs you would expect from normal use but two of the plastic leg-connectors and two sections of the leg-spreader had been shattered as if someone had used them for Karate practice! Having read much on SGL about the ne
  13. I do most of my observing with a 200p mounted on an EQ5 Onstep Goto powered by a 12 volt leisure battery. I'm putting together a second, more portable setup using a smaller scope on an EQ3-2 dual-axis tracking mount which needs 6 volt power. This can use 4 x 1.5 volt "D" cells, which are a pain to keep replacing, or 4 rechargeable 1.2 volt cells which will work fine, but I'd have to buy a suitable charger. I could just buy a 12v/6v DC "buck" converter to use with my spare 12v battery but where's the fun in that? Looking in my box of "Electrical bits that are bound to come in us
  14. Don't complain. If a distant neighbour still has his Christmas lights up you can use them to align your finder. And if they include a well illuminated shiny bauble you may be able to use it for a star test on a cloudy night. "Always look on the bright side of life."
  15. If anyone is looking for a used Skyliner 200p dobsonian there is one for sale in Bridgnorth, on Facebook Marketplace. No connection with seller.
