Live stacking with 102mm frac

On 25th March I tried some live stacking with Sharpcap and a 102mm f5 Startravel achromat & ASI120MC camera.

Mount was Celestron SLT on custom tripod.  Image size: 1280x960.

With this setup it is possible to dial in an object to the GoTo and be confident that it will appear on the laptop screen.

These images may not look too exciting but they do mimic the FOV and general appearance as seen in a 203mm SCT with 25mm EP. Check the image for M87. When I checked the field in Stellarium I found that two faint non-star smudges matched with NGC4478 and NGC4476, which are 11th and 12th mag galaxies.  I am gob-smacked that I managed to image these with such modest equipment from an urban site.   There is no way I would be able to see these visually even with a C8 from here.
