PST First Light

Hi All,

I have just had my first play with my new PST and all i can say is wow!

Having only previously looked at the sun in white light i found the difference profound especially when the proms popped into view, there was a massive one which looked very impressive. I was also very pleased to see the granulated surface texture.

I dont generally do much visual work these days but i found it difficult to take my eye away from the eyepiece as the Sun was just too captivating.

I attempted to take some images but i was beaten by time, technology and my own lack of preparedness. I couldnt get my DSLR to focus no matter what combination of empty/full Barlow i tried so i switched to the Dion cam. I couldnt get properly focused with this either but that was down to my own incompetence as i had only secured the dovetail bar with one bolt which i had not tightened properly as i could not find an imperial Allan Key (just done some ebaying so this wont happen again - Allan key set and Whitworth bolts are ordered) so the movement while focussing was impossible.......

I was not too disapointed with the imaging mess as it was the first time i had tried it and nothing goes well first time and just looking through it pretty much blew me away.

I cant recommend having a look through a PST highly enough as i have only previously seen the Sun like this on here and TV which simply is not the same.

Thanks for reading.

Any tips greatfully recieved!!

It's fantastic isn't it! :)) To get focus with the Dion cam you will need to screw the lens from the skywatcher barlow onto the adapter. ;)

It certainly is Brian, i managed to have a few hours playing again this morning, about to post the results.

Strangly the web cam focusses fine straight in the ep holder but the only way i could get the DSLR to focus was to screw the X2 Barlow lens onto the end of the T to 1.25" adaptor, very odd but its all working now thankfully.

Spent some more time just looking through the scope, there were quite a few proms but only one small Sun spot region.

Just couldn't get out again today. :( The region you saw would be 11429 - it seems to be splitting up a bit now but it's still big. Sunspots themselves are less obvious in Ha but the regions around them are really interesting. :))

:mexwave: very addictive old Sol...the problem with dslrs is that most tmount nose adapters have a lip on them, so the pst eyepiece holder won't fit flush enough. So need to grind or file the tmount nose lip off to give the extra 3mm needed to focus... May have found a Chinese engineering firm that can make them for me, so watch this space....
