My PST is back !!!
I wasnt sure where to post this but on balance thought it belongs in this forum rather than general chat..
My PST is back-no doubt you have noticed the clouds around Sydney-after being sent to the US for repair
all in in took about four weeks which I think is pretty good seeing I shipped it to Adelaide, from there it was sent to the US for repair, then back to Adelaide and from there to me in Sydney
HUGE difference!!!
didnt try to image or anything just took it out now as the sun broke through the clouds and the visual difference is startling
earlier-with a deteriorating objective lens i could see prominances and no surface detail at all..now plenty of surface detail is visible..can see filaments and the sun's surface quite clearly, as well as prominances and some fine detail
the sweet spot effect is now noticeable-there is a well defined area in the eyepiece where the image snaps into focus..earlier i suppose there was no sweet spot at all, the whole image was so degraded
and its no wonder I struggled to image before
so its something for all PST owners to watch out for-the dreaded bloom ..and the attached picture shows what to look out for if you havent seen it elsewhere
