Hi Lars,
I went out the shoot a Jupiter-Moon lunar two night ago and took a look at Jupiter and then Saturn to see if there was significant side error. I found little... the Jupiter reflected image merged into the real image. The Saturn reflected image partially merged into the real image. My last two lunars produced Errors in Lunar of .08' and -.5' respectively. So I'm not sure that the side effect is acutally affecting the LD itself. So, if there is little sideerror and the LD's appear to be reasonable, I'm still not sure what could be causing the .2minute discrepancy to the SD's...
