Absolutely get at least one 2"EP. I have a 30mm 80 deg. with a 1.5x barlow
that came with it, from Andrews. I also bought the 15mm, and they were
one of the best buys I ever made. The 30mm gives a truly immersive
experience, and the optical quality is amazing for the price. I expect the prices have risen by now, but I paid around $175 all up for both EP's and the barlow. My favourite 1.25"EP is my Unitron 20mm Erfle that I got 30 yrs
ago. It's a ripper. Almost as good is my 25mm Koenig[25 yrs old].
Incidentally, unusually,the 2"barlow screws onto whichever EP you are using.
happy viewing

P.S. If you have not been up close and personal with 2"EP's you will be surprised at the size and weight. The 30 mm weighs a little more than my Canon 1100D.[about 570grams].
