William Optics GT81 Image Scale

This is a Video on my Choice of a Refractor DeepSky imaging telescope along with its Unboxing. William Optics is a Optical equipment manufacturing company from Taiwan. My choice was to buy the 102 mm version of GranTurismo model, however the 102 model is discontinued and hence I had to go for GT81. I have not yet ordered the Field flattener with this scope, however had first light with my Canon 600d, i have managed to collect some 2h or data for Orion Nebula from a bortle 8+ sky, will make a separate video on my experience with this scope. One more reason for me to but GT81 was that with all gears + Scope weight the total payload for my mount CEM40G will be around 12 to 13 KG, which falls in the sweet spot of 50-60% of Rated load capacity of CEM40. I have also explained in this video what is the field of view expected when pared with four different cameras and what is the Image scale with the GT81, GT102 and Canon 300mm lens, and which is over sampled and which is Undersampled.
