Stacking images from 2 different scopes

[Carole]

I did a 2nd lot of imaging of the Witch's Broom (after the Crescent disappeared behind the dome).  I was aware that my previous subs were done on the ED80 and I was now using the ED120, it was too late to start swapping scopes and unscrewing piggy back kit etc etc (early hours).

I have stacked images using different scopes before in DSS and it worked OK then.  

However this time it will not stack.  (I'm trying to stack the two resulting stacks together, I haven't tried doing it in groups as that produced strange diagonal striations last time I did that).

Any suggestions of a way I can get these two to stack?
Same orientation, might be a slight rotation but not much.

Might be worth visiting this page sometimes

I've read the thread Mark has put on first:

As I have photoshop and am fairly au fait with that I'll start with this first.  

Chris's comment on the attached thread

you can get both images in photoshop align a single star set that point and then drag the image and rotate it into place

How do you "set a point"?
I've tried stretching the image in photoshop already (I need to change the size more than the rotation).

I'll now read the thread Robert attached.
Oh dear it doesn't seem to lead anywhere  

thanks

yes it does,
It leads to the sarcasm page.

Me thinks he has telling you to try using the search first.

It's OK, I have managed to stack it in groups in DSS.  Not sure that the extra data is an improvement though

Oh yes, I'm a bit slow on the uptake with sarcasm.

I do try using search sometimes but if you don't word it right you don't find anything, and even if you put something simple in it doesn't always find what you are looking for even though I remember a post on the subject.

i.e. Was looking for Mark's Albireo thread earlier to see how mine compared with it and just put in Albireo and it never found it.

Carole,

I don't know why you had a problem - I managed to find Albireo by doing a search:

Well I just tried it again and all I got was this thread and my own Albireo thread.

Maybe I am using the wrong Search function.  I'm using the one at the top right of the page.

Just tried the other Search function (between Help and Profile) and yes it does come up with that one.  I wonder why one works and the other doesn't?

Very nice Mark - Like the way you grabbed another opportunity to show off one of your images
