I have used the long perng planetarys 3mm&5mm they showed cromatic aberation on the moon, so i sold the 5. I have been using 4,5,and 6mm tmb planetarys for several months now. A recent buy was a 12mm smart astronomy solar system long eyerelief eyepiece. These eyepieces must be an update on the long perng le eyepieces. This eyepiece has no CA and has better internal light baffleing than the tmbs. In fact i got cleaner views on the moon using it with a 2x barlow than using the 6mm tmb on its own. I am now looking to replace my tmbs with more of the smart astronomy long eyerelief solar system eyepieces.
