Altair Starwave Ascent102mm ED F11 review & Skywatcher AZ-EQ6- GT

Brand new bargain priced & high quality 102mm f11 ed doublet astronomical telescope,purchased from altair astro in the united kingdom,february 2021. Skywatcher mount/tripod & mount accessories was purchased second hand.Its only 3 years old. Forgot to mention- Retractable dew shield,that holds its position when extended,and firm when retracted. Dew heaters have car sun shield insulators velcroed onto the outside,to keep the heat in and preventing the outside of the dew heater band getting wet from dew. Telescope tube rings are inner felt lined & are fit for the purpose. x5 threaded holes are all M6 in diameter. They are NOT 1/4 inch threaded holes. 102mm objective has perfect coatings when viewed with a bright led torch,no anomalies were seen. Whilst observing sirius,the first very bright star of my two star alignment in altaz mode,it showed NO sign of purple fringing (chromatic abberation) or unwanted false color. Easy to focus due to long focal length-F11. Sky is a velvet black background. Telescope has deep sky object(s)capabilities,especially from a dark sky observing site. Great planetary viewing scope. Cheap plossl eyepieces can also be used,as this scope is forgiving on eyepieces due to its long focal length of F11. Rack and pinion focuser holds firm even with a 20mm APM lunt 100 degree 2 inch eyepiece weighing 670 grams,in the 2 inch star diaganol. No slippage of the focuser draw tube at all. The mount MUST be facing NORTH,BEFORE powering ON the mount in altaz mode.. This applies for both the southern & northern hemispheres. The skywatcher mount was quickly aligned using a two star alignment in altaz mode.The first bright star for the two star alignment was Sirius in the north east, high up in the sky.The second bright star chosen was Canopus which was located in the southern sky also high up in the sky. Observing is done by sitting down on a chair,rather than standing up. EQ6 mount weighs approx 15kg WITHOUT the counterweight(s) attached. Altaz mode is best for my use,as it requires no polar alignment,only a quick two star alignment. IMPORTANT-when storing/transporting the EQ6/AZ GTI mount head in a case,make sure to leave BOTH the RA and DEC clutches LOOSE,not tight..This prevents damaging the expensive stepper motors,from bumps/knocks,encountered when transporting in a car boot for example. NOTE-My camera automatically stopped recording at 10 minutes,so i could not show more-sorry. Video was filmed in Melbourne city,victoria,AUSTRALIA.
