Hi Chris, I have the Skywatcher 130p. It's a great little scope too. I highly recommend you make a shroud for your 150p as it makes a fair difference to the view stopping any unwanted light getting in. I also found it stops breath from fogging the secondary mirror. I used black 3mm epa foam . If you search 130p upgrades on youtube you will find a few tutorials. A lot of people do this and it is totally worth it.
Cheers, Richard
