Hi Again, While the Luminance for the mosaic didn't quite work out at 5x5 panes, due to the Eagle getting its wings clipped, I had to add another row to the top. I missed the final pane in the top right. This is something I hope to finish soon, and which will will then give me a wider view of the top, allowing the eagle lots of room to flap. Anyway in this version I have managed to angle a crop to get the Eagle, just about, in the frame. So now this just leaves the final 3 rows of RGB, or I guess 4 rows really. This is 60mins Lum per pane, and a crop of 29 frames. Taken with the Tak FSQ106N and Atik 11000, between May 2012 and June 2013. While this region has been done before by Rogelio, and the phenomenal 50 pane picture from Stephane Guisard, both were taken with the focal reducer, so while I can't match Stephanes picture for data, this is of a higher resolution. Another one for the wall at home if I can find a wall big enough. Even though there is only an hour per pane, this is a bright region of the sky so there is a good signal present. Stitching was done by creating a base layer with Star Align in Pixinsight. Then using Gradient Merger Mosaic, I created a better more accurate base layer from the star aligned files. I then had to go to Registar to individually match each pane to the base layer, which I then stitched together in CS2. The same GMM PI base layer was then used for the RGB panes to match to in registar. So despite some small areas where the join was not perfect, I do hope to be able to combine the RGB data, and the Lum as 2 huge but separate layers either for PI or PS. This will help a lot with colour saturation, balancing the image for brightness, contrast, and sharpness etc.. I've posted an image on Flickr which might be a bit larger than this attachment. http://www.flickr.co...N02/9157592351/ There are lots of beautifully shaped dark nebulae in the image, open and globular clusters and even small planetary nebulae in there that I did not notice until I went to check the stars charts.

Help! I think there's astimatism in my new FSQ
jackrussell0232 posted a topic in Discussions - Scopes / Whole setups
Gents, Ladies, please don't laugh (you can gloat of course), but I'm getting acquainted with a new FSQ106ED. At the same time, I'm testing a GM1000HPS (still...) Odd star shapes have occasionally come with the territory so far with this mount, but I had some very strange results with the 'new Q'. The long and short of this, is that I've discovered that slightly out of focus stars are elongated in one direction, and this direction swings thro 90 degrees when I go from intra to extra focal positions. The fully defocused star images look round enough, but this is really disappointing. I'm just hoping someone can reassure me that this is not normal, and that I should get it replaced rather than just refunded. I know Ian K will look after me, his service is always excellent, just want to make sure it's not just me that thinks this isn't good enough. Any advice welcome, Jack
