  1. Very grab and go. I have a set of pockets round the ex-camera tripod I use so scope/mount, batteries and eye pieces can be taken in altogether. The azgti does need carefull altitude balancing, as in don’t switch weight of eyepieces. If you unbalance it can have tracking issues. Peter
  2. If there is no risk of it being bent then you should be OK. The machines I have can handle a 20cm cube, So would be fine. Good luck peter
  3. It’s early in the season, hopefully plenty of more attempts possible. Peter
  4. Cold feet - muck Arctic sport will sort you out. When you get to good skies, you don’t want anything to cut the session short (apart from the sunrise)! Peter
  5. Great to see people getting out to dark skies! Such a shame the coffee couldn’t have given you a crack at the Cone... hope you won’t have to wait long for another outing. Peter
  6. ....the curse of Bartels “one eyepiece, many scopes” philosophy! Of course if you “open the other eye” your brain can now do clever stuff with the extra information- reduce noise, improve contrast... even Mel is moving this way (albeit in his super sized, super fast way), should enable him to dredge up yet more IFN for the rest of us. Peter
  7. 3dprint-U.K. do SLS nylon, you pay for the bounding volume so you could pack extra goodies inside for the same cost. Any bureau using the HP FusionJet would be good too - high throughput machine. If you FDM it I would be tempted to add a few longitudinal ribs inside (if the design allows), just to lower any risk of delamination from flexing. If you use a tough material and print thick layers you won’t need to bother.... I always like to make sure prints aren’t too fragile... stops end users questioning the technology. peter
  8. Good to hear it delivers... easier than setting the Explore. Peter
  9. I’ve printed some dovetailed bits for attaching GPS and lasers to things. Cheap 3D printers tend to stop at around 20cm size prints. The bigger the part the longer it’ll take to print. What sort of size is the part you’re after? Peter
  10. There are epoxy based coati by a you can apply if you want smooth and water proof. The only time I heated a part of up in an over it melted and left a small puddle! How have people got on with leaving prints outdoors, how long does PLA take to get damaged? I print solid PVDF for pretty much everything proof parts, not the cheapest though. With printing non-PLA do watch out for fumes. Peter
  11. Pictures or it didn’t happen!we expect a full report Magnus! Peter
  12. I use an f4 newtonian so the Explore corrector allows me to keep the speed for the field of view. Found I didn’t need it for how I was observing last time. With the corrector I have a long stack of optics looking like a thick broom handle poking out the scope... hazardous! Peter
  13. Slows the focal ratio of your scope too. I have the explore model that keep the focal ratio the same. Not done a huge amount of assessment with it yet though. Peter
  14. you can get angled binoculars, but not in your price range. A medium Mak would be compact and show high power things and could go on an altaz mount. peter
