Thank you, gentleman, for your contributions to my query. The straight through scope or the angled scope question is definitely a good topic for discussion from the aviation enthusiast point of view. Now, if money was no object one of the more expensive draw scopes from Swarovski from about £549 up would be the job but it is hard to justify such an amount of expense as per Heathrow Director's comment above on pricey scopes so that is out of the running for me. I am inclined to consider the Celestron Ultima models that are more modesty priced and the brand seems to be well got amongst the astronomy enthusiasts. Birdwatching magazine are recommending an Avian model, the Avian Multiview 80, but in their review they would like a tad more eye-relief.
Thank you, Heathrow Director, for the tip about using an attached straw to line up the object for viewing with the angled scope. Such effective simplicity!
