  1. With my last HEQ5 Pro mount and EQMOD I could measure an absolute max throughput of 14 kB/s. But mostly it stayed around 4-5 kB/s.
  2. I have used a 5i5RYH i5 NUC at scope. It was designed to use 12 volts and performed very well at this voltage. Other NUC-s need 19 volts. Check specs before buying. Christer, Sweden
  3. As long as you plan to only feed stick with 5 V power, I believe it will not use more than 1,2 A. I have a m5 stick and it needs no more than that. If you need to feed devices via USB ports on the stick, you have to add that. Using 6 V and dry cells is not good. Better will be to use rechargable batteries with 1,2 V, totalling in 4,8 V.
  4. There is a review in latest Astronomy Technology Today. https://astronomytechnologytoday.com/ Christer, Sweden
  5. Thinking of all the strange surplus items Lidl sell besides food, I would not have been too surprised to find this case WITH EP-s in! Christer, Sweden
  6. More of a chemical or electro-chemical reason. To charge a lead-acid battery, the alternator output must exceed a certain minimum voltage, which is 13.8 volts. But at this voltage full charge will take forever. For reasonable charging times a voltage of 14.2-14.7 volts must be applied to the battery. Higher voltages than that will only increase production of hydrogen gas and not shorten charging times significantly. So for electronics to work in a car, they must accept a voltage of 11 to 15 volts. Most electronics specs state this as something like 12 V +- 20 %. Lower voltage will need more amps...

  7. Sorted? How? Four members try to help you and you just tell us it is sorted. If you want help, you must be prepared to give something back. Not just run away... Christer ,Sweden
  8. Yes, or AV is more "aware" of github files after this: https://blog.avast.com/greedy-cybercriminals-host-malware-on-github?ref=cj&utm_medium=affiliate&utm_source=commissionjunction&couponfield=yes Christer, Sweden
  9. If calculator at http://www.ccdware.com/resources/dust.cfm is correct the dust is 3.8 mm from sensor surface (pixel size 5.7 µm - f 5). Christer, Sweden
  10. ...or try online calculator: http://www.ccdware.com/resources/dust.cfm Christer

  12. Sorted it out? Really? And how did you fix it? Christer
  13. Hello! I had to write a new post due to problems linking images from Dropbox. Also a member wanted me to update post. So nothing new, laser still working... When away from home I use QHY Polemaster for aligning. Works like a charm and one gets a little bit spoiled when PA is so quick and precise. But I missed a good way to align when doing balcony astronomy from home. I have good South view but can not see Polaris so Polemaster is useless. So I decided to create my own NCP, haha. I started by nailing 3 claw tee nuts into my floor, to have tripod at same place every time: I used protective lid from Polemaster adapter and mounted a small laser in it: Mounted to my HEQ5 it looks like this. I use a small 3 volt battry box for supplying power to the laser. Then I used several hours to do a very precise drift aligning, using DARV procedure. After doing a few measurements and calculations, I printed a target table and glued it close to balcony ceiling. Looks like this with laser dot in the middle of the small center circle. Numbers are degrees off NCP. Now I can carry out mount and tripod and with the aid from laser have a very good PA, often close to 0,1 degree. Also during full daylight. This idea can be used for every mount. The laser can be pointed to any surface, only important thing is it must be rock solid in respect to the mount. Christer
