The overall finish of the Quantum-7.4s seemed to be of a better standard, with all surfaces exuding quality
.A hardwood tripod and U-fork mount, which did the job perfectly, made observations at the zenith very comfortable, with the 45° angled view
.There wasnt as much trailing off of image quality towards the edges
.Stars really filled the field of view and we felt like we were falling through the sky. This was matched by views of the Moon that were incredibly detailed
.Visually the Quantum-7.4s seemed to have the edge on all the others
.The sky background appeared to be the darkest of the four on test, with better contrast, so deep-sky objects like faint nebulae stood out slightly better. Indeed the nebula M17 displayed a mottled surface and was a wonderful smudge in the sky
