  1. Sorry I don’t have any details in the gearing. Would interested to hear how you get on
  2. Sounds like a power issue to me. Have had an AVX for 5 years. Use to run on a battery and experienced all sorts of weirdness, including the mount diving down to look at the centre of the Earth! Try mains power, though appreciate you will need to purchase a PSU to confirm this. The Baader one from FLO is excellent but not cheap....
  3. I really like the composition. I might give it a try with my Star 71, never considered a widefield image on this area.
  4. Thanks. I have to setup and pull down my kit each time so would need it to portable. I guess the it could be adapted to allow this.
  5. Having recently upgraded my mount I am looking to try some imaging with my Celestron 8" again. Now I know this OTA is not ideally suited to imaging but with the F6.3 reducer and knowing that a certain degree of cropping the edges will be required I am willing to give it another go. I have seen some very impressive results from this OTA and the fact its Galaxy season its giving me an opportunity to continue my imaging. My question is what flat panels do you guys use on the larger OTA's? For my small refractor I use a 3" the Aurora Flat panels which whilst are not always regarded as being the most solidly built accessory it has served me very well. https://www.gerdneumann.net/english/astrofotografie-parts-astrophotography/aurora-flatfield-panels/uebersicht-aurora-flatfield-panels-overview.html However paying 155 euros which lets be honest will be £160+ with shipping etc then that feels a little more than I would like to spend. Any ideas? Please note that I have zero DIY skills so really looking for a ready made solution... Thanks!
  6. This is my final image with my Celestron AVX mount. Due to poor imaging conditions so far this winter and the fact the nebula is rapidly disappearing behind a neighbour’s house, it as usual not a great amount of imaging time. HA: 75mins (Chroma 3nm) 3x1500 secs O3: 2.5 hours (Chroma 3nm) 6x1500 secs Total: 3.5 hours. The fact I have only been able to get 75mins of HA (3 subs?!) gives you an idea of the lack of opportunity. Still I wanted to at least get the chance to add O3 for a Bi-Colour image. (Click image for a better perspective)
  7. Be aware the handset display alignment. If it says zeros across the board then it is likely that that is not correct. Been a while but check out the AVX Mount thread. It discusses this on there in fact I recall posting threads on there about handset alignment myself. That said if you are getting good stars then looks like you have it sorted.
  8. I cable straight to my laptop. I think the mount one is ST4 guiding only. I use PHD2 with pulse guiding. Cables are my nemesis and have recently worked on taming them. Factor in cable for camera, maybe a polemaster not to mention all of the power. Tearing in all down after each session is a pain so spend time on making it easier for you if you have to setup each time. Obviously the AVX does not have a huge payload capability so try to keep weight down. My tripod is covered with Velcro so I can attach power supplies to. Check out you tube for ideas.
  9. Thanks Micky. That’s very useful information. Will arrange a session exclusively for guiding despite the draw of doing imaging instead!
  10. I have / had an AVX. I plugged a serial cable into the handset (the one that comes with the mount is fine) and then had a USB gender changer so that the serial went to USB on the laptop. Then had a USB Guide camera that connected to the laptop. Used PHD2 for guiding and SGP to control the mount and camera. Don't have any guides. Be patient with the AVX but I managed to get 25 mins exposures with pin sharp stars. Though I was using a short focal length and OAG to get this. Good luck.
  11. Thank you Scott. I will certainly look at basing my PHD settings on your suggestions. Certainly sounds like significant differences, gives me hope on improving my guiding. Just need some clear skies...
  12. Hi Scott., I managed to get out last night and test the mount. Other than a few niggles such as new SGP profiles needing filter wheels re-adding (my fault) then things pretty well. Following my usual routine I Polar Aligned though the Elevation bolts namely the spring loaded one is interesting. When I wanted to come further down in degrees I loosened it off but found I needed to manually move the mount forward to actually bring the elevation down if that makes sense. I should re-read the manual as I didn't spend a lot of time on this, anyway I got good PA. After focusing I used the handset and typed in dates and time (having to keep remember putting handset into EQ Direct mode!) Elevation was already there just entered through Polar Alignment section. Said No to align. Plate Solved at Polaris area. Then opened SGP and used a Slew now to get to rough area. Then used Center Now. First plate solve was out as normal, Second attempt was spot on, I think it was a single pixel out! Normally on AVX I had a max of 28 pixels so that was encouraging. BTW I am using Plate Solve 2 (no Internet access) and I have ANSVR setup with local copy as you describe. I find Plate Solve 2 always works. Began PHD and configured guiding. Despite changing the PHD profile to the new mount some of the settings were clearly not correct compared to the old AVX. Namely calibration steps. After I received "Star not move enough" I checked the Brain icon and noted this was recommending a way high value than previously, 6100 whereas it would have been around 700. Re-ran and this time it worked. Guiding started off woeful. Kept changing settings and by the end of the night I was around 0.90RMS. However much of the evening was way, way above this. My payload is only 16 pounds. The values I ended up with were as below. I suspect I will need to fine tune these but if you have any suggestions on value then that would be much appreciated. Not had to play around with PHD2 values for a while and I now remember how challenging it can be to get the best results. All in all a good night. Everything worked but needs fine tuning.
  13. Hi Scott, Thanks for your post. that's given me great reassurance. Last night I ran some tests to simulate my current routine and the mount appeared to behave exactly as I wanted it to. Obviously I cannot perform a plate solve inside but it gave confidence that I am on the right path. A couple of questions though. I will be buying the EQ Direct cable soon but even with the handset /cable how do you tell the mount the date and time? I guess this is what I have entered into EQ Mod already? The handset knows my latitude /longitude is that also passed to the mount itself? Secondly the handset keeps asking me about Polar co-ordinates which I have just entered through, is that okay as I will be Polar aligning with my Polemaster? Lastly the manual keeps referring to Alignment points. But I see no alignment points in the Alignment Point List Editor window. Is this simply because I have not added any and I wont need to add any as I will be using Plate Solving? That RMS figure sounds great. My current setup is way below half the weight of yours so hopefully I will be able to achieve the same sort of values. Hopefully will post results when I get some clear skies. Thanks
  14. Thanks Micky. Yes will be getting cable very soon (next week I suspect) but just wanted to get a idea of what to expect as things can get confusing when in the dark trying to sort this. Also cannot fully test plate solving until outside. So if I Pole Align with my Polemaster. Then use SGP to Plate Solve at Polaris as a means of creating an alignment point in EQ Mod then this would the same as performing a 1 Star Alignment? I would then set this as the Park point as well. This is what I did with the AVX before doing the Quick Alignment option on the AVX handset. After this I would then perform a solve and synch plate solve in SGP for the target image, preloaded by me. Also do I need the other ASCOM SkyWatcher SynScan Mount Controller (6.0.6262, June 2017) , is this as well as the EQ Mod EQASCOM driver? Thanks
