  1. If it helps I did ascertain when building mine that it is the same base as an EQ6 so you may have more luck searching for that.
  2. I had exactly this problem, on the 8 minute worm cycle. So I concluded an eccentric worm or big swarf in there somewhere. I just spoke to the retailer and they replaced the mount after I ran Synta's test protocol to prove the fact. The replacement has no such issue so I am much happier. It is not acceptable to have such issues on new products. The more Synta hear that directly or via warranty claims the better their QC should get. I don't see the advantage of going in blind whilst comeback remains a justifiable option. The mount is way better than my original HEQ5 pro in its ease of use and construction but then maybe I have learnt how to deal efficiently with Synta's idiosyncrasies.
  3. Just finished my third course 'Gravity'. 6 weeks of excellent content thanks to a Parisian University and George Smoot.

  4. Great news. Please can you remove the iPad bug whereby every time i use it I get 'Failed to find current location'. It does eventually find it but after restarting the App.
  5. Yes the subs are great. I think its a flats issue but I'm still experimenting. Flats are important for the 300 f4 because of significant vignetting on my chip.
  6. I'm not quite in a position to contribute to that yet but not far off. I am stacking 3 hours of data today for the horse head taken using my 300 f4. However I have an issue with DSS with this data so am struggling. I get a weird zig zag gradient across the stacked tiff. I've never seen this before. Normal gradients are expected but this is weird.
  7. No, the corners are not flat on a big sensor. Probably OK on smaller sensors. Now, my 60mm macro is as flat as a pancake.
  8. As above. I have the 300 f4 L. At f4 focusing is extremely tricky. Compared to my frac at f5.59 then the field is not flat either on my crop sensor.
  9. I feel for you Gnomus. I have virtually the same issue with my refractor which it is claimed produces a flat field even on a full frame sensor and it has at last been picked up by the supplier after me sending very similar corner crops and other data. My findings point to (and my gut feeling is that) the likelihood the collimation is slightly out as Olly says above. However, mine was almost a third of the price of yours. I wish you good luck and I will follow your plight.
  10. Have you consulted this thread? On the second page Ian posts an excellent diagram of the consequences of incorrect spacing. http://stargazerslounge.com/topic/225831-flattener-spacing/page-2
  11. Yes, the GTX site has the info. I also did the trial but I can't remember if I added GTX at that point or after the purchase.
  12. Another possibility is that the trial version has limited functionality of course.
  13. Hi Peter, GTX and various other plug ins work fine on my PS CC but I am running on Mac and so have the Mac versions downloaded. Is it a win problem maybe? I can go and find out how I did it if you wish?
  14. Just started a new course. Astronomy: Exploring time and space. Uni of Arizona

  15. The simple way I got my head around this was to take a normal image, I used my M42, put it into Photoshop and choose LAB mode. Then if you look at each channel in this mode it is possible to see how much information is contained in the luminance channel compared with the others, most of it to be honest. An expert imager may come along soon and explain it.
  16. Read Mike's excellent post, then read it again. Most stuff is in LEO and what isn't is moving much slower (or apparently not at all) relative to our vista. I see such events sometimes here. It's the Army playing in their Apaches.
  17. Hi Alistair, here is a bit of info in my thread: http://stargazerslounge.com/topic/224854-heq5-pro-worm-drive-bearings/?hl=worm+bearings#entry2428931
  18. Thank you very much. Follows up the Planetary Nebula post very nicely.
  19. Passed my Coursera Intro to Astronomy course with 87.6%. Very enjoyable.

  20. Hi Gary, I'm not much of an expert in guiding to be honest, although i do manage it with PHD2 but my guiding pixel scale is 5.15"/px.
  21. The thing that stands out to me from your thread is the FL of your guide scope. 800mm is longer than most imaging scopes. Mine is 328mm and that is consider long for guiding. I'm not familiar with the camera type you describe. Are you using PHD 1 or 2 as 2 automatically steps the gain up and down until a suitable star is selected.
  22. Started fitting out new obsy. Drift align tonight hopefully.

  23. Waiting for better weather and to finalise obsy plans so ordered Rowan belt mod.
