A few proms

Some poor seeing today with a hazy sky but I caught some nice proms.
DMK21 and Ha PST - No barlow

Very poor seeing today, a short break in the coud enabled me to catch some proms

Full disc- Active Region

Some are calling this a small sunspot - other call it an active region. Either way, there has been some change since yesterday!

PST Focus Knob CNC upgrade

My upgrade focus knob arrived today from Criterion Machine Co in West Virginia, USA. It is nicely machines in aluminium, coloured gold and slips over the normal focusser so no actual mods to the PST are required. A small grub screw holds it in place and an allen key is included. It cost $20USD and I am very happy with it. It makes reaching focus a painless experience.

First light with the DMK, very poor today with just a few gaps in the cloud.

This was my first use of the PST on 1st August 2008 for the partial solar eclipse.
