Fine for that Houghy, thats what its designed for. Thats a very good price, is that the 1 Nat has listed on Astromart?
Very high quality well made scope that should last about 3,000 years. The optical quality and mechanical construction will be infinitely superior to the Chinese made Mak Casses and its also be a better performer and higher quality product than either the 5" Meade Mak Cass or the 5" Celestron SCT. It also utilises a different design to those other Mak Cass BTW. The Intes Micro 503 utilises the Rumak design whereas the normal "built to a price" Mak Casses utilise the Gregory design. The Rumak design uses a separate secondary mirror whereas the Gregory design uses a silvered spot on the back of the corrector.
If you have a use for that type of scope I would be buying it yesterday, its a steal
