I had my 25 mm pocket Borg, the worlds smallest astronomical telescope, out last night using an Altair 15mm and celestron 9mm eyepiece. I was pretty impressed with the view of Jupiter,cloud bands just visible with the 9mm eyepiece but I think that the view in the 15mm was better but less detailed. I may invest in a wide field 5mm eyepiece which should zoom it up to about 35x .even with the 15mm a tripod was essential for any long holding but it is possible to use it hand held for short periods. Due to the bright evenings only managed one m object m39 in it.
