Beautiful pic, but as for aspirations I'm going to stick my neck out and say its quite possible to achieve 90% of the quality of that pic with 10% of the expense.
Sure its a huge help having great gear, but just go back through this forum's deep space threads for Eta and you'll be pleasantly surprised what many people have done with refractors 4" and under and reflectors 10" and under on chinese equatorial mounts.
Like most things though, once you master the basics and want to go all out, then getting that last 10-20% performance REALLY costs. There's just so much fun beginners can have though with under $5000 of gear.
Oops - rant over. Really is a fantastic pic...
