Hi there. I recently picked up a celestron Omni XLT 127 Telescope. It comes with a 25mm lens and was thinking of getting a few extra bits with the goal of hopefully seeing Saturn's rings and clouds on Jupiter, possibly some galaxies etc.
My thoughts were to get a x 2 Barlow lens but not sure what mm sized eyepiece to get. I know there is some calculation you can do with focal length etc but said I would just ask here in case I miss some detail.
Also I wear glasses myself so is there some brands of eyepieces that are best for people who wear glasses?
Any suggestions would be much appreciated,
