Ok - so here is what is happening;
I recreated the integrated channel masters for the Bottom sub exposures using NSG. They created as normal and each file has a FITS header.
When I create the RGB combined file via Channel Combination using the F…
I was afraid of that - I saw that myself but thought I must have done something wrong. Not sure how that happened either. I'll need to recreate that file. Thanks for confirming.
Ok - spoke too soon. Ran MosaicByCoordinates and got the error below. Apparently the Top RGB Tile is Ok but the Bottom RGB Tile has a problem; could not read WCS Coordinates. I've sent a DropBox link with the Tiles. Just

Ok thanks - I double checked the parameters you mentioned (I never use drizzle but I double checked that I didn't have drizzle files after alignment) and the advanced parameters. I did change one item - I used the active window instead of adding th…
Thanks Adam; sorry I thought I'd captured everything in the screen print. I didn't think of an issue where catalogs were't complete but it makes sense.

Thanks a lot for taking the time to look into this. Yes, I saw the data was vignetted and cloudy but it is consistent with data I've received from this telescope previously (AUS-2; Takahashi FSQ-106EX & FLI PL16803 camera). There is even a warn…
For the small stars with only one or 2 pixels with problems, all of the black bits did go away after integration. Only the large star with many (20 or so) pixels with problems still had a few pixels with black bits that I fixed with the Clone Stamp …
Thanks - no, I didn't think it would be easy to do but I was challenged to come up with anything at the time to work on the subs.
These subs are what I received from my imaging request of this object from Telescope Live. The equipment used was AUS-…
Thanks - I did use drizzle initially when I discovered this problem. I went back and reprocessed the sub exposures from the beginning and but I did not use drizzle. The result this time was much better; a lot of the problem was resolved with the e…
