Hi Gary, welcome to the forum, you may find either eyepiece a little bulky for the 102 Mak (does it have a 2" visual back?) but both ep's will work well with the SW 150 PDS. Do you wear spectacles for viewing? This will make your choices a little more sensitive, as the ES ep's tend to have short eye relief (the distance of the eye from the ep), in which case ep's with long eye-relief are better, also it would help us to know what targets you want to view, bearing in mind that the ES 24mm is a low power ep (31x on your SW 150PDS, 54x on your Orion 102 Mak). The Baader 8-24 mk iv is a jack of all trades and this, I suspect would be a good choice for a beginner (at 8mm the ep would give you a comfortable 162x on the Mak, which is a great setting for the planets and Moon.
Good luck and clear skies!
