This is my first 2 pane Mosaic.  Captured in HaRGB.

This needs more data but chances are unlikely, so I have posted it for now.

The Flaming star panel had a bit more data than the Tadpoles section as it clouded over before I had finished.

Flaming star:
12 x Ha (2 hours)
RGB 15 x 150secs binned
Total 2hours 37.5mins

Tadpoles:
9 x 600secs Ha (1.5 hours)
RGB 14 x 150secs binned
Total 2hours 5mins

Grand total for the Mosaic = 4 hours 43.5 mins

Atik460EX Baader 3nm Ha filter Baader RGB filters
WOZS71 and HEQ5
Mapped HaRHaGB

Combining the panels was a bit of a challenge, as I don't have a licence for APP and prefer to use software I am familiar with if possible.  Despite doing both panels on the same evening without moving anything except the mount I was surprised to find a small amount of rotation when i tried to stitch the Ha panels together, and Registar did not want to register the panes even though there was a reasonable overlap, so had to rotate the Ha in Photoshop.  I was then able to use this merged mosaic to register the RGB files. 


Got a tip about using ICE for stitching Mosaic's together and so did a general reprocess, I think this version is better and certainly a lot easier than doing it manually.  So image replaced.

Was wondering why I didn't get any feedback on this image, looks like I forgot to post the actual image!!! 

Duh!

Nice one , ive always wondered how you do a mosaic,

I am sure there are more sophisticated ways of doing one, but I tend to do things the old fashioned way.

First of all I studied the FOV of both targets in Imaging toolbox and established that it would all fit in two images and where the overlap would be and where I had to place the images.  I also checked this with looping before I started. 

My sensor is placed orthogonally, so I merely positioned the Flaming star in the corner so all i had to do was manually move in one axis to the second target with an overlap.  The first process I did manually in Photoshop and had a bit of difficulty registering the two images as there seemed to be a little rotation doing it on separate nights (not sure how that happened).  Also getting the colour to match of each half was a struggle.

Then some-one told me about ICE which I downloaded and all I had to do was feed in the two processed images and bobs your uncle, even fine tuned matched the colours too.  Clever software and it's free.

I think APP has a number of ways to make mosaic's simple, but I didn't want to have to pay for and learn a completely new software for what could be just one image.
