Subject: Re: [Astro_IIDC] star images...


P.S. I did notice with the camera inside, attached to Astro IIDC & pointed at a room light that depending upon settings sometimes I`d get light registering in the CC window sometimes not. A couple of times I had to turn Astro IIDC off & on again to get the camera to work properly & this may have been what was confusing me out at the scope..?

Last time out (2 nights ago) I was having trouble obtaining any traces
of star images with my Scorpion. I`m not entirely sure (Betelgeuse
which I was using) was on the chip as I was getting cloud obscure
first Betelgeuse then Rigel (& back again all night). On my 3 star
alignment Betelgeuse & Procyon were much brighter than the star I`d
selected as Rigel (I don`t know if this was due to clouds)?This may
have put my Go-To out, though Betelgeuse was centred in the eyepiece.
I`ve re-looked at the Manual & the sharpness (& FWHM- HFD section). Is
there a rule of thumb for exposure readings-(I know it`d vary from
camera to camera). I couldn`t focus upon this star anywhere in the
range. I did manage to get the extended PGR exposure times working
with a plastic bag tie taped into the GPIO pin out. I tried both with
this switched on & off... Into the bargain my finder had been bumped
removing the scope cover & wasn`t very accurate. Last night was
perfect but I didn`t get out, feeling too frazzled. Probably too much
information but yesterday began with a car accident on our dirt-
gravel road-A woman had rolled her car near us & we had to help
getting her out of the wreck...!
