Thanks for the advice. What you suggest makes sense. Baby steps and all of
Back in June I was able to incrementally improve on my alignment and imaging.
Until the Monsoon season hit, the Canon temperatures soared, and I had to bring
the scope back in. Every time I move the scope, I have to start all over and it
takes me several outings to get back to where I was. :-( Some of that is due to
my inexperience/lack of skill and some is due just to my poor location in
Chandler. (The Celestron alignment routine likes to pick stars I canât make
out due to the light pollution and my poor initial alignment.)
Hereâs my best guided image so far:
Itâs not up to Bernardâs or Tomâs standards but it was getting close to
my version of âacceptableâ. PHD2 was reporting guiding errors of around
0.18, if I remember correctly. The 3 minute exposure limitation was my Canon
camera, not the guiding. Or so I think.
I may do as you suggest, sticking to mono for the first night. (I was hoping I
could leave my scope set up on Saturday so I didnât have to start completely
from scratch the second night but the predicted winds on Saturday afternoon may
require me to take everything down. Weâll see.) If the first night turns out
OK, then maybe Iâll try a LRGB target for fun on the second night. Or maybe
go back to the Crescent Nebula and do L/Ha.
But the AASP is already a success for me. Itâs forced me to get all of my
stuff arranged so I can take it out of my backyard!

OK then.... now we have a better "insight" to you and your equipment.
If I might suggest....
To take advantage of the weekend and the dark skies (if they are not
CMOS cameras are very fast. Forget the guiding for right now. You are trying
to learn your camera, and what to expect.
Take 30 sec unguided images (all Luminance). Time for color later.
You need to learn to anticipate exposure results for various times. Will
reasonable polar alignment, you "should" get 30-sec will little issue.
If you feel like to you want to play... try some 30-sec with RGB (after the
luminance).... but I would suggest NOT dwelling on it.
Then... at home, in the comfort of your own back yard... you can work on
polar alignment, and guiding... (any ole target) and again, just luminance.
Get guiding figured out.
After you do that, then you can start trying LRGB, and combining. But that
will come later.
What I am suggesting here is to reduce the variables, and concentrate on
mastering one thing at a time, and over time, build on that.
Is luminance only any good? Well, I have over 4000 images on my web-site,
all indexed, and 99% luminance only. So.... I think so.
Remember, Astronomy is a hobby. You want to be having fun. And... you want
to be learning.... one thing at a time.
I won't be out there, but maybe some time later, we can get together over
here at my place, and maybe I can guide you some... if interested.
Not sure what part of town you are in.... I am in Tempe.
