Hi
I got a couple of hours out the back when storm clouds cleared the night beofre last. Fitted spacers and MPCC on to st2000xcm and tried it out on the Lagoon. The MPCC as I would expect has given me tighter stars and flatter field as it used to with my 350D but then I had a new problem ..... frost on my sensor .... so I am currently regenerating the desiccant .... 4 hours in the oven at 175 degrees C. I had noticed a little frosting the previous session but it was not as bad.
Anyway I have attached a shot with frost and a crop without. Frosted version is straight out of DSS with no post processing.
This is not a post because I think the M8 cropped image is great it's just to show the frosting really. Even with the MPCC I had bad tracking/guiding performance etc so slightly eggy stars if you look close ... so don't look !!!
;)
:thumbsup:
Oh the exposure was 5x300sec @ -12 with my 200mm newt - IDAS LPS2 - UV/IR - MPCC .... then I called it quits.
