“With StarSense 130 mm using eyepieces of 10mm (65x) and 25mm (26x) magnification, how do we achieve higher magnifications for viewing? Specs report up to 307x magnification. Does higher level magnification require barlow lens and/or additional eyepieces?”

Yes, purchasing a Barlow 2x will double magnification of included eye pieces. Celestron sells Barlow separately, and in various kits with additional eyepieces, filters, etc. Be sure to get matching 1.25” Barlow, eyepieces.
Sorry, there was a problem.

However, most seeing conditions will not allow such high magnification as any atmospheric turbulence will blur and distort the image.
Sorry, there was a problem. Please try again later.The use of a good Barlow lens will increase practical magnification. The "maximum" magnification is just a number, usually around 60 times the aperture [in inches]. In this case: 130 mm / 25.4 mm per inch = 5.12 times 60 = 307x magnification. Good quality Barlow lens will be able to increase the practical magnification by a factor of 2x up about 3x. The use of specific filters may further enhance the quality of the image depending on the celestial object of choice. A good system enhancement starting point would be a set of basic filters and a 2X Barlow lens.
