No Im in a situation where I can only veiw from SE - SW but have produced reasonable images, this is new

Many thanks Steve, I will try that Thanks Olly

Can you dither manually without software, say with your hanhset while exposing , if so how, thanks

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

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

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

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 !!

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

How long an exposure can you obtain with that without serious star trails

Hi how long an exposure can you obtain with that rig

Is this not 12v?

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
