Stu1smartcookie Posted October 25, 2022 Share Posted October 25, 2022 Hi Dave , the ST120 is a widefield Achromat and being a short Tube will have Chromatic aberation on bright stars and Planets . I have owned one. In fact this was going to be my "ideal" scope at one point as it has a good sized aperture for the money . I did find however that looking at doubles such as Albireo and its companion the colours of the stars were not that pronounced . Having said all of that , £80 is a steal for this scope . So , why not give it a try ... and dont forget you can get rid of a lot of CA in pocessing . Stu Link to comment Share on other sites More sharing options...

Cosmic Geoff Posted October 26, 2022 Share Posted October 26, 2022 A steal at £80. I have used the smaller Startravel 102 extensively for EAA imaging. It works well enough that I don't want to spend £1000 or so on an APO to see if it's significantly better. 1 1 Link to comment Share on other sites More sharing options...
