That's quite impressive. How did you get rid of the CA on the Achro in that shot?
I'm planning a trip and I won't be able to take my reflector, so I'll be limited to my old trusty 70mm achro, which I ditched because I could never get a handle on that CA. I'm planning to upgrade to a ED at least, but I can't fit that on my budget yet. So any tips will be more than welcome.
I happened to own a SvBony CLS clip in filter for Canon APS-C, it works like a charm!
I do have some shots without the clip in filter and managed to colour correct for the CA in Photoshop. Not the most convenient task but it does the job.
If I have any tip to offer, that is: I load the mount east heavy as it does improve guiding accuracy by a huge margin for my iEXOS100.
Note that all of my shots on the Z73 was almost reaching the mount's max suggested payload. (19lbs)
Looking forward, I decided to get a dedicated QHY 183M. Will post it soon!
I too have 'upgraded' to a William Optics Zenithstar 61 Apochromatic Doublet. Reason being that while an Achro will still do reasonably well with the QHY 183M, stars tend to bloat and i certainly did not want to watse the potential of this amazing camera (quite a bang for the buck!)
And also afterall, this thread is for what you can do with a budget mount/tracker regardless of any imaging equipment/accesories we all have
Happy shooting and happy posting
