The question is, are you intending to use this for astrophotography, or visual ?
This is optimised for astrophotography and as a quintuplet it means that while it has a large flat field, near the centre a triplet or doublet ED APO with a somewhat longer f-ratio may be desirable. The other aspect is that the focusser will be set up for cameras which may be less than ideal for visual with some eyepieces + star diagonal.
If you're a visual observer you could get a larger scope for that money.
