Hi everyone,
I’m currently imaging with a Celestron SLT 130 (650 mm, f/5) and ASI662MC, and I’m thinking about adding a Barlow / focal extender to increase image scale for small targets.
I’m considering the Tele Vue Powermate and Explore Scientific Focal Extender.
If you’ve used either of these, I’d really appreciate hearing your experience with the image quality (sharpness, star shapes, etc.) in real-world use.
Thanks in advance! Clear Skies!
