I managed to image Corona Australis but again hampered by weather.
I also found I had imaged the same thing under the same conditions
using my AstroPhysics 140 scope and same camera about 2 months ago.
So the 2 images are much the same exposure (the AP had more usable luminance) so it provides an interesting comparison between an AP140 and a TEC180 fluorite.
The images look much the same except for image scale and of course the larger aperture gets a bit more detail.
TEC 180FL LRGB 20 10 10 10

AP 140 LRGB 40 10 20 10

same camera (Apogee U16M) same mount and location, smilar weather conditions, the TEC shot the object was higher in the sky but it was also under a 2/3rds moon whereas the AP140 was during no moon.
Both are super scopes.
Of course both of these shots are really really short total exposure time.
