Hi John,
Thanks for the advice. The dark frame subtracter mentioned in Covingtons was very easy to use.
This is basically my first picture of a star cluster (the jewel box), not very good but I hope to improve. This is 5 stacked 1 minute images on an EOS 300D with no guiding and dark frame subtraction.
I have another question
. If i got say a Lumicon Giant Easy Guider but used it on my alt az mount. Would i still get field rotation if i kept the guide star centered?
I took some other pictures but anything much over a minute i get pretty circles so am looking for a way to do astrophotography without polar alignment, but dont know if this is possible.
Thanks Paul
