Yes.
The Quality reading is the one that really matters - a default reading such as you've got indicates you are not aligned, let alone to a specific cluster like Astra 1. The proof only comes when you scan and actually get some Channels - even then a standard error is to be "on the wrong Satellite". ie Similar Transponder parameters are used on different positions so if you scan a pre-store list apparently"belonging" to one Satellite, whilst you are actually pointing at another Satellite, you will get some results - but not the ones you expected!
You are looking for a needle in a haystack that is 24,000miles away: Any error in either the direction or elevation of the Dish means you will miss the Satellite by miles and miles and miles ............... so gentle movements of the Dish only (No waving it around!) and lots of patience.
