These are the latest images I’ve taken with my 127 and C90, back to back on the same night with the same kit (HEQ5 Pro, 2x barlow, ZWO ADC and ASI-120MC). Each time I’ve taken the best 25% of 10000 frames using AutoStakkert, and then performed wavelet sharpening in Registax.
Previously I made the following comparison between 127 and 102.

Jupiter in August 2019 with a Skymax 127 and a Celestron C90.
Venus, the waning Moon and Jupiter low in the south-eastern sky at 6am on 31st January 2019. About four degrees separates each planet from the moon. Handheld shot using a 700D and a 50mm lens.
The closest line of sight meeting of the red and blue planet for 200 years. 75% cloud and showers at 17:30UT.
Mars with a Celestron C90. Syrtis Major coming into view on the right, with bright Hellas below.
Jupiter on 28th June 18, getting lower in the southern sky after sunset. Good seeing for once allowed use of a 3x barlow. Happy with the result!
Jupiter and the GRS, May 19th 2017. Kenko 3″ refractor.
The planet Mercury taken 45 minutes after sunset on 1st April 17 with a Circle-K 3″ refractor I bought on ebay. Happy with the scope. Classic ‘frac.
Venus after sunset on 15th March 2017. Taken with a Celestron C90 and a x2 Barlow.
Uranus forming a triangle with 88 and Zeta Piscium. WO GT81s with 8s exposure.
Zoomed-in view of Neptune showing the vivid blue colour. Beautiful!
