  1. My flight-compatible setup is what you'rw considering: Az-Gti, 130 Flextube and a Sirui carbon fiber tripod. Fits in cabin luggage. 130 flextube does sit ok on Az-Gti though the overall setup is rather wobbly on high powers. Also with limited tripod leg spread it's somewhat easy to knock over though that has not happened thus far.
  2. This probably has something to do with the Synscan app not behaving well on the newest Android 8.x. Had no problems on an older Samsung, does not work on new Nokia 6.1.
  3. Selling the thing would indeed appear to be the best solution if you don't have the equipment to make use of the lens.
  4. How smooth is the tracking on SolarQuest? I find that with my AzGti there's a constant jitter in the tracking as the movement jumps appear discernible (vs. e.g. Star Discovery mount tracking) even at the lowish powers used for solar observing.
  5. Any chance the central block could in fact be an IR pass filter?
  6. I'm beginning to think this is a common issue with the SW Star Discovery mount. My first SWSD stopped slewing in AZ very often, got it replaced and now the second one is doing the same thing regularly. I think the issue is not power as the AZ motor is running, but rather that the friction between the motor drive and the rotating mount part is not sufficient. The tightness of AZ is not externally adjustable, but there probably is internally some adjustment possibility.
  7. I use the SW Star Discovery altaz goto mount with my Lunt 60. I find the solar tracking to be very nice when it works, and it works reasonably reliably. It's also sufficient for short solar imaging runs. Edit: I als occasionally use the mount with SW 100ED and lunt solar wedge. Gets a bit wobbly when focusing but otherwise also good
  8. While I understand that going with binos helps with detail scaling, i'd hazard a guess that color loss due to dimness is still there as cones do not get enough light to get stimulated to begin with. Increasing aperture is would naturally help in many ways, but does not address the question "what's a good EP for my telescope X for seeing object Y". With 100ED there's also the benefit that e.g. for me setup from zero -> tracking takes <5min. Finally I don't think the Delites qualify as exotic, they're just basic high-quality EPs
  9. An innocent question here: wouldn't a binoviewer + barlow in 100ED, which is already pretty dim at ~150x, make Jupiter pretty much undesirably dim?
  10. Yes, at least subjectively for me. I was originally considering a Vixen SLV 6mm, but decided to go for the 7mm since I felt the problems at 5mm were quite significant and wanted to get a clear difference. The 7mm Delite (which is, BTW, excessively comfortable with eye placement) fits all Galilean moons in FOV, so I would hazard a guess that for Jupiter the wider FOV of a Nagler would be wasted.
  11. AZ Goto has such low power requirement especially when tracking that I found the Celestron LiFePO4 to be quite perfect. Not very expensive, reasonable sealed and works for days without recharge when tracking the sun. Only issues for me have been that the charge indicator is difficult to read (indicator led lighting splits between spots) and the rubber cover hinges snapped after a cold night. Otherwise perfect.
  12. I just got the 7mm Delite for my 100ED precisely for Jupiter viewing. I felt it's the optimal focal length in terms of magnification (large enough Jup), brightness (can see colours) and exit pupil size (some floaters but not too bad). In my 5mm X-Cel LX Jupiter was washed out in terms of color, seeing issues were very apparent and floaters distracting. With the 7mm got to see GRS in color
  13. ..and this tracking depends on the mount being level, although in practise leveling by eye seems to be sufficient.
  14. In the most recent Synscan firmware version you have solar tracking mode inbuilt. Just enter date/time info, no alignment, point to sun and activate solar tracking from the utility menu
  15. I've used the HEQ5 wih 200PDS and it's fine for visual as long as there is no wind, and can take a camera for limited unguided imaging. A focus motor is necessary to avoid bad wobbling on focusing. With guidescope etc. the total weight is too much for the mount.
  16. I have experienced the same problem. Somewhere it was recommended that one should remove the compression ring, leaving only the screws. Haven't tried this yet.
  17. I just checked the Celestron cable plug. The contact part is about 12-13mm long and the plug fits also directly into my AZ Goto mount.
  18. You're correct in that there is no cigar socket. I'm using the supplied power cable with an added 90deg adapter (for avoiding "tripped on wire" PCB breaks) which seems to get a solid connection at least on my SW AZ GoTo mount, so I don't know if the cable on its own would have issues. In any case most of my past power issues have been caused by a dislodged cigar socket connector, so I would say anything is an improvement on that ;-)
  19. I got one recently, mostly for powering a SW AltAz GoTo. Seems to be a solid unit, can be strapped to tripod leg (a bit awkward with thin legs) or hung from the tripod. LiFePo should be relatively safe and the construction appears sturdy. Also fits nicely into same size carrying case as eyepieces etc.
  20. I have the Baader 2.25x barlow. It can be used both with 1.25" eyepieces and T-thread adapted cameras. It has a very solid build. Of the optics I don't feel I have enough experience yet to comment in detail. I had one go at Jupiter with it and 70D at 1:1 video crop on 200PDS, which did show some false color especially around Io. Then again seeing was pretty bad and focus was probably a bit off too. I was just in a rush to record something as the clouds were rolling in
  21. This is very curious, since that grub screw was significantly angled compared to the others to begin with, had not touched the puck ever since coming from the factory (no contact marks on puck surface) and I had not completely removed it at any point from the threads. Perhaps it had been brutalized a bit at the factory and I mistaked it for incorrect screw threading. But in any case I trust the puck connection is now secure and look forward to getting the mount back in action.
  22. I have 200PDS and 130PDS. 200 is a bit much for HEQ5, absolutely no margin for wind. 130 is very fine size-wise, but 200 os signifcantly better for small targets with thw longer focal length.
  23. It appears some HEQ5s are special snowflakes regarding their dimensions with the belt mod. Mine had the measurements as expected by Rowan, but still it required extra spacers to fit the motors deeper so that the cover was not touching anything. In any case Rowan provided very good support with getting the motors in the right place
  24. I also had similar trouble when recently doing the belt mod, but was able to eventually wiggle the extractor over the pinion. The tolerances seem to be extremely tight with the fit.
  25. Wuthton, paul_astro, Thanks for the helpful comments! I'll go with having the defect professionally fixed this time, but on longer term I'll be surely looking at widening my toolset to include hole tapping capabilities.
