  1. Hi single shots even at 30 secs are OK and Ive checked and cleaned all the optics
  2. The image has not been turned it is as you see
  3. I have attached 2 images from last night using an H-Apha filter due to the Moon being up, however the target was well away from it and should according to the Filter specifacation not effect Ha imaging. I reduced the exposure to 60 seconds as suggested by many and set iso at 3200 ( grainy but a good setting for accenting the problem) 10 and 5 exposures, stacked them with Deepskystacker, part processed on PS . As you will see it has made no difference whatsoever to the rotating marking or smearing effect I have checked the optics in the Scope and the DSLR Could this be a camera sensor fault or dodgy DSS software, although it stacks with no effort. I have tried every settng on "Preference" on DSS inclusing the ones for Ha images, makes no difference Im now at a loss as to what to try next
  4. No Im in a situation where I can only veiw from SE - SW but have produced reasonable images, this is new
  5. Many thanks Steve, I will try that Thanks Olly
  6. Can you dither manually without software, say with your hanhset while exposing , if so how, thanks
  7. Thanks chaps for your help. The Horsehead target was only 45 degrees and I have just processed some images taken last night using iso 1600 and 90 seconds again at the Horsehead and the images have the same rotation problem. I have tuned this mount and it does now produce good images at 90 seconds iso 1600 at even higher altitude than 45 degrees, the attached image is at those settings
  8. Thanks for replying. I know that AltAz mounts are prone to this rotation, however the stars are not elongated and using DeepSkyStacker this should handle this small amount of rotation that these 6 frames developed or maybe not
  9. Can anyonetell me what is causing this circuling, Im using a WO Z71 on a iOpton AZ Goto mount 3mins @iso 3200 , high I know but for testing. I have a Flattener fitted which is variable but have set it at 71. I have attached 2 images stretched to show the problem. the object was at appox 45 degrees altitude, low Moon well away from the Horsehead, the first image was with a Ha filter and the other without any. I know a alt az mount is not ideal for imaging but I have had reasonable results before
  10. I've emailed Altair Astro but still waiting for an answer and now have contacted iOptron support and again waiting, meanwhile my warranty expiration gets nearer !!
  11. Can anyone tell me where I can download a "Strip down" or repair manual or instructions for this Mount, I have a knocking noise on slewing and need to inspect it
  12. I have tried altering the balance as Sub Dwarf suggested and Davey-T I am using a newly replaced unit as the previous one was worse - Demon[erformer, I put the wrong image on but it shows that the trails differ in direction when alter the weight/ balance etc . I will look up the link.
  13. Star Adventurer, Canon DSLR - Williams Optics ZS61 Telescope ;; I am getting double and treble joined up stars when imaging when imaging only at 60 seconds. I have carefully balanced the Mount and Scope and polar lined well. I have been advised that it is cable snagging but I have no cables. Ive tried various movements of the weights and scope, It is a heavy duty Tripod , weighted and on anti vibration mounts, It is though the mount is badly tracking and taking multi shots joined together, My 2 test images are a full one and it zoomed shot at 45o alt East. Am I asking too much from this mount, I would like to track at 2 mins
  14. How long an exposure can you obtain with that without serious star trails
  15. I have Tracer 12volt Power Pack which I used successfully on an iOpton Star Tracker, can I use it on a Star Adventurer or must I use 6v. I hate internal AA Batteries, prefer remote but like others the ones I’ve used keep cutting out
  16. I have just purchased a AZ Pro and am delighted with it, although the goto quite often misses the target despite levelling it to the degree. Visual is great but I expect no long exposures with regard to imaging. I have a 8" RC on it and use a Canon DSLR, also a WO 71mm for wide. I would like to know the exposures I can expect.
  17. i have recently purchased a iOptron AZ Pro, which I am pleased with however I cant make it work via the wifi on my ipad using Sky Safari plus, as is advertised, the mount connects to my ipad OK and I can connect to the mounts wifi. In setting I enter as instructed, SkiFi number 10.10.100.254, Port 8899. I could not find the Scope type AZ Pro isted so I chose the handset 8407 also alt/az, however despite this it will not connect to the scope. I have tried this with my iPhone but the same. I have contacted the dealer and iOptron but not received a reply, can any one help
  18. Many thanks Kerry, good report. I have a RC 8" so dont have problems cooling down
  19. I am considering in upgrading my Minitower 2 to the AZ Pro, I operate ftrom a patio with my house behind obstructing mt view of the North and North East, would this be a proble as it is automatic in its line up on a Star. Has anyone any views on this model, Im happy with the Minitower 2 I have but its beginning to have niggly problems, thus the possible ugrade. I tried to contact Altair Astro but they do not return my email or calls ???
  20. This Dob is set up by pointing it level North, raising it to Polaris, North, and pressing Set Latitude, so it can't be that, also the Alt slew in the right direction therefore it's only down to the AZ one which in the wrong direction
  21. My SW tracking Dob AZ motor is running in the wrong direction, the ALT direction is OK. I set the scope up facing North as usual, any ideas anyone?
