A few questions (from the owner of amongst other things a 5" MAK)

1. Does it come with a 10:1 fine focuser - else you likely want to add one, cheapest way is likely a SCT fine focuser like BinTel sell for around $129?

2. Is the rear draw tube milled to 2" or 1.25" or a wierd size that needs a specialist converter tube if you ever want to attach said 2" SCT fine focuser (not too expensive to buy converter ring - just hard to find).

3. Cool down times are a bit longer with a MAK

4. Agree all those wider angle and lower magnification eye piece suggestions

5. Note MAKs have a tad longer cool down time to reach maximum optical stability than SCTs from memory

6. MAKs may not be coliminatable (if that's a word) or more challenging to do - check if it come well colliminated from the store - or find out if it can be done by them optimially before they ship it to you! Wouldn't suggest a noew owner try this the first time with their first scope!

7. Like SCTs - MAKs are a good compromise in portability and optical performance for what they are designed for! PArticularily when focused well - suggest you get a Bhatinov mask for your scope.
