  1. If I read that page correctly they don't say that Ubuntu 20.10 will run on the older models, just that Ubuntu is available on them. 😲 For any readers of this thread see Ubuntu page for their coverage of the various Pi flavours.
  2. I presume you mean with the Nikon attached you will take & save an image at each appropiate stage asked and use the virtual camera to open it. Whether the polar alignment routine has the option to open the image is another matter. Prior to Sharpcap having the polar routine and before Polemaster one of the forum members created a polar alignment program which uses saved images and would prompt you in a slightly more manual way. See PhotoPolarAlign if I recall correctly you can download and use test images to get the hang of it.
  3. I use a program called Rufus for writing Linux images to sd-card, found here. Though I do have a usb3 adapter for sd-cards, so it's normally done in around 10 mins.
  4. The usual work arounds revolve on boosting the ASIair signal through an extender. For example: 1. Use an external device to boost your home wi-fi. If the device is DC powered and next to the mount you can use a wifi connection or possibly a lan connection between the ASIair and the extender. 2. If the extender is in house or garage but near enough to let the ASIair get a good signal then use that. I have one of these in my garage to extend my wifi signal for the garden and rear of house. 3. Use an extender to boost the ASIair wifi broadcast signal into the house. 4. For portable and away from home there are a lot who use a TPLink device (such as TP-Link AC750/TL-WR902AC) to do create a hotspot for their phone/ipad and ASIair to connect to. This video gives you an idea why the Rasberry Pi has a hard job broadcasting a wifi hot-spot, given the size it's amazing what it can achieve.
  5. I seem to recall that the wifi on Raspberry does not have any way to use an external connection and is limited to the onboard aerial - there are some daring individuals that cut the traces on the Pi board and add an external connection but not something the normal or even expert would probably want to try. You may have seen usb wifi connections with nice big aerials but whether the ASIair Pro could use that over the internal one is the key question.
  6. Yes trustworthy and well known in the Hertford Astonomy Group. I have even collected gear I purchased from his house in person - so no worries with him.
  8. Check the basics: Is mount securely bolted to the pier? Are the PA bolts tight after PA set/corrected? If the mechanicals are correct then PA should not change as dratically as yours in a fixed mount setup. User Polemaster to avoid any confusion with date/time/location. Once PA set do a goto and if off adjust that using the clutches, then do a park and mark that on the mount with tape. Then further goto should be accurate. After that as you are using via computer rather than handset include platesolve sotware to do the goto and adjust them. With guiding and platesolve the PA can be a little off and you should not need to PA each time.
  9. That's how I did mine but I cheated and added a lnk with pictures that shows this method 🙂
  10. Hi Bill welcome to SGL, We will try and help getting you up to speed. It appears that you have polar aligned the scope which is the hard part. The computer star alignment is based on your mount being in the correct home position and having the date and long/lat set correctly. If any of these are out then it will not take you to chosen alignment point correctly. Basically the scope would be pointing up (12 o'clock position if you think of the scope being the hands of the clock), whilst the weights would be vertical (or at the lowest point of the arc when the mount is moved). Some mounts have scales that can be set to show this as zero against a mark on the mount and can be adjusted by loosening a locking screw. So if the date is set correct (it may want date in US format) and the long/lat/time is set correctly try with the weights parallel with the leg and see if that gets you nearer to the first alignment star. If it does and the remaining alignments and goto stars are OK then tell the mount to park in home position and mark that position for next time (some tape and a marker pen). See this page for an idea of how to set your home position starting point.
  11. There is also the AstroHat project that is being followed on the IndiLib forum here Again it needs skills with small soldering.
  12. Perhaps: A wooden or red perspex sheet that sits on the 2 tube rings using the upper screws. Would be easy to drill/stick the Pi on to. Or for proper style a Losmandy-type Universal Dovetail as a base plate something like this, other colours, makes & sellers available 🙂
  13. It would be a nice touch to try the free alternative software SkEye on Android with the same adapter hardware. If it works almost or as good then we just need a 3d printer guru to come up with a diy adapter 🙂 though I suppose it may not like the mirrored view captured.
  14. There is a driver for Indilib see here not looked at Ascom as it's a PI hat.
  15. You could consider adding a stepper motor hat ( for example the waveshare aound £20) which would drive a focuser without the need for another power connection and usb port - plus it can run the Pi from a 12v feed too. Though that depends on what focus motor you are planning to add. The case for your Pi looks very project friendly, was it purchased or diy/3d printed?
  16. 'Bear in mind' the deed has now been done. Hope it has all gone as you hoped and views well.
  17. If you have an HEQ5 then probably your tripod is the SW 1.75" stainless steel one already. If you wanted to get a sturdier 2" stainless steel one then either a used CG5 which is a 2" leg version but fits HEQ5/EQ5 - can be hard to find, or the EQ6 one but that needs a £50 adapter. Are you using the legs fully extended? Perhaps consider keeping them short and buy an eq5 extension pillar to fit on your existing tripod.
  18. If you have PA and RA sorted then DEC has to be OK, the axis is 90% to RA and is not adjustable.
  19. Consider the opposite way where your mount was fixed and had no adjustment bolts. If your pier/tripod started perfectly horizontal you would need to adjust it to centre the mount axis with the NCP. It does not matter too much if you adjust the pier or the mount as long as the axis ends up correctly aligned, it's just a little easier (and cheaper) to use the mounts adjusters.
  20. That last snug turn would mis-align the polarscope though Never use the polarscope now, the Handset polar alignment was good enough for an accurate setting until I used a permanent pier setup and the Polar Align software from Themos (a forum member) provided an even better one.
  21. I'm using PC windows and a local astrometry without astrotortilla and found what was needed. If the api field is empty it does not save all settings (I guess that's a check for the new user to make initial settings) just put a number in the api key box. Second the config file is for the location of the astrometry config (mine is /etc/astrometry/backend.cfg) Just need to get the solve settings and local copies of the solve files all tidied up for the cameras I plan to use. Will be using the local solve for SGP too. Hope that helps.
  22. I had a slightly larger error, but small enough I thought, so I tightened everything up to keep the settings and took one last image - but it would not solve. In the morning I uploaded the image manually and it would still not solve until I processed it to make it clearer, must have been some thin cloud that I'd not noticed as the image timings were constant and all earlier attempts were solved fine. So quite pleased the final settings, after tightening everything, ended up the best. BTW. A couple of points I thought worth mentioning: If a poor image is uploaded and the server takes too long while attempting to resolve should PPA handle that?Instead of having an extra button for Nova & Local for each image would it be tidier to have a select radio button to set either Local or Nova and have just one Solve for each?Not sure if using AstroArt5 as a solver will work, although it does have SDK for scripting I'm still having issues using it directly so would not hold out any hope of linking to it. A local nova on the other hand sounds a good idea.
  23. Managed to spend a bit of time getting the alignment as good as I could before the hour got too late or the clouds started to interfere. I hope this is accurate enough to use when I get my guiding setup finished. Once you get the feel for the amount and direction of changes to make on the mount alt/azz bolts it becomes quite easy. I was using a DMK21 with focal reducer and live view so I could almost work out the rough position the stars needed to move to beofre taking and uploading an image. Would have been a lot easier if my computer was nearer the scope, the latop was hooked up in the garage so was popping in/out each time to check improvements. Thanks Themos that's a real nice utility for alignment Steve
