Re: [APML] New TP pictures

[Duncan Munro <dmunro@sfu.ca>]

You can't beat techpan for it's deepspace "mood".  I really enjoyed the 
other techpan shots as well. I can't seem to find any info on David's 
equipment. I'm really curious to know what mount he's using.

 Also,I wonder what is causing the single spike effect on  the bright 
star in the M101 image. This effect is also present in the M81 image as 
well. I am getting a similar "single spike" effect with my 10" SCT and I 
suspect it may be caused by by dewzapper running at too high an amperage 
but maybe someone has an alternate explanation?

cheers
