Thank you for posting link - informative video but as mentioned by others, the inclusion of 'music' (in my opinion) detracts from the value presented. I was thinking of suggesting to re-editing (removal of sound track other than you talking and related sounds e.g. ambient stuff) but guess given the total number of views to date you have better things to do i.e. more observing!
Not sure why a later video you made available watched did not seem as interesting, the style used on 433 Eros seems to have been a 'good' formula for success... Just my 2c worth.
Wishing you clear and dark skies.
