  1. Thanks. I was surprised at how much info I managed to collect with 1.5 second exposures. The high iso reallt helped. Once I get a tracking mount I'll need to find the sweet spot between noise iso and data captured. I had a clear night tonight here in glasgow but its 8 below. Hope u manage to get something! My next target is the rosette nebula I think
  2. Thanks for the info. I have been looking at that specific lens. Outstanding results with it. I also looked at the az gti but for some reason was slightly worried about polar alignment with it for tracking. I realise it's a matter of proper research regarding that mount and the go to function seems really useful. I already have a 9x50 finder I bought for guiding years ago with am old spc 900 webcam that I didn't have much if any luck with but from what I can see things seem way more simple and affordable now. I also love the idea of those asiair but again wasn't sure if the Sony was compatible or not... I need to learn more about plate solving and tracking/guiding to work out exactly what I'll need to get but it sounds like maybe a guide camera , asiair mini and the azgti then the samyang/rokinon 135mm f2 could be somewhat close to a good portable kit I can have some fun with. Thanks for the recommendations
  3. I also read the same thing so was disappointed that maybe the a7iii that I mainly bought for video a few years back might not be suitable. I turned off all noise reduction and gave it a go at the ridiculous iso. I'm wondering if it would be worth spending 260 quid on one of those ebay astromodified canon 600d's I had considered getting the star adventurer again but have been looking at a few others like that can hold more weight. Lots to think about and research. I was thinking if I got a star adventurer with a basic zwo 120mm guiding setup and a decent 200mm lens I could reduce my iso to maybe 6400 and hope for some 120 second ish exposures to clean things up a little. Just can't pull the trigger on anything at the moment however and keep looking at heavier duty mounts and ed refractors etc. Not sure the type of shooting I want to do. I actually enjoyed the quick and easy setup of just a tripod haha
  4. Thanks. Yeah for sure... calibration frames would for sure clean it up a little. It was a last minute idea I had and just put the stuff in the car and drove up slightly under prepared for the -4 temperature. I found the lens in a bag of lenses I had and had no idea of the quality so I wasn't taking things too seriously on location. Just happy to be out in total darkness enjoying the view while the internal intervelometer?? :s Did its thing
  5. OK I know its got a lot wrong.... but before I start spending on mounts and what not I thought I'd take a short drive to a bortle 5 and see what I could do with just my camera. This is a helios 135mm f2.8 lens at f4 Iso 25000 Sony a7iii I think its around 200x1.5 sec exposures in a bortle 5 sky. No darks or flat or anything but glad to get out at least and visually look at the sky after a 9 Yr break from it. Got a lot to learn but in 9 years it's good to see how the technology has moved along and lots of great you tube channels and info out there now. Stars are going crazy but hey... I managed to get a faint and noisey horse head in there The andromeda is around 160 x 3 seconds with a tt artisans leica mount 50mm f1.4 at 2.8 Both are super cropped
  6. Hi everyone. I used to do some astrophotography years ago. At the time I used an 80mm refractor and dslr on a star adventurer and had a basic autoguiding setup with my laptop. I since sold the tracker but still have the scope. My question... I was looking at the latest star adventurer which then got me looking at scopes and mounts etc. I always remembered fancying the 130pds so I know I would need a mount suitable for this and from memory rhe eq5 was the bare minimum required. For the most part I'll be using my little 80mm refractor for now and my Sony a7iii with lenses for wide field messing about. Would an eq5 with the dual motor add on do the same star tracking job I'm looking for as the star adventurer with the possibility of maybe adding a 130 scope in the future? Or would I be better off just getting the star adventurer for the 80mm and camera or the eq5. The 130 scope is an after thought but even for visual use I'm sure the eq5 might have its benefits. I have plenty of really solid tri pods for large format 8x10 photography I can use for the star adventurer so it's not the tripod I'm concerned about it's really just the mount and its ability to give me 90-120 seconds exposures at a push for now without extra guidance. Sorry for the long winded post but I cannot find a specific answer to this and I'm really keen to hear your opinions. Thanks Iain
