I am not too familiar with Sirius. Apogee eyepieces are not too bad. Plossel type eyepieces are good all around optics. If you are spending about $70 for these eyepieces then you might consider buying Celestron. Reason is that their threaded barrel inside fits almost all filters. Meades and some of the better ones will not. 4 element Plossels are good and they are easy to maintain. Also are you buying 32mm because it's there, or because you want a wider field? With a 4.5" 26 or 25mm is ideal. Of course 32mm is OK too, but a little more pricey. Perhaps you could spend the money on a Barlow lens.
