Excellent in all ways

I bought this ES focal extender for a gift; I already know how well Explore Scientific products perform. I’ve used their eyepieces, now the scope and accessories are going to a nephew so I added the focal extender. Red Carpet handled the sale and delivery deftly and I’ll bookmark their site.
