.. at a reasonable price. I know the powermate would be a sure shot but it's too expensive and I plan to use this Barlow just for the Mars opposition then I'll have to wait for another couple of years before having planets like Jupiter and Saturn at a decent altitude here in the northern hemisphere. The telescope I'll use it's a C11 and the camera an ASI290MM
Of all the Barlow I've seen online these are the ones I consider reasonably priced:
TS Optics TSShorty 2x Apo Barlow, 1.25 inch, 3-element: https://www.teleskop...nd-astroph.html
APM 2" Barlow Lens 1.5x/2x w. Adapter 2"/1.25": https://www.teleskop...r-2--1-25-.html
Celestron 2x Barlow X-Cel : https://www.teleskop...-3-element.html
Explore Scientific 2x Focal Extender 1.25 inch: https://www.astrosho...ab_bar_1_select
You may need to translate the first 3 links to English, there's the flag icon on the top right.
Any good experience with one these barlows? Also any other candidate to add to the list would be more than welcome.
Thanks and Clear Skies,
