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 (upper left) and Neptune (lower right, blue dot) on 2nd January 2017, using a Canon DSLR and a WO GT81. 10s exposure.
Zoomed-in view of Neptune showing the vivid blue colour. Beautiful!
[caption id="attachment_1274" align="aligncenter" width="408"] Mars on 18th June 2016 at 23:30pm, taken through a SkyMax 150 using a 2x Barlow. The seeing was poor and the planet was low down in the southern sky. 200 frames was all I could get between the clouds.
