Hi all,


This is my first attempt at a mosaic. I did a 9 panel, 101 hours total integration time LRGBHa on the small Magellanic cloud region.

The data was taken from July 2nd 2020 to September 21 2020. It was by far the hardest thing I ever imaged. I had to battle through different atmospheric conditions, wind, snow!, and technical issues.


Did I do well? Probably not. Did I do bad? probably so. But I learned a lot from it. I know my reducer spacing was a bit off so the stars aren't perfect.


My conclusions are that it is better to take each panel to completion before continuing to the next one when its more than 2-3 panels mosaic.

I find this region fascinating with plenty of Ha zones and the combination of NGC292 and 47 Tuc is beautiful to me. I'm lucky to have it above ahead during winter months here.


I'll probably go back to reprocess it in a while. I need a bit of a break from it to get some perspective. 

Maybe add more panels next year to include a bit more around this.


I would very much appreciate any comments and criticism. 


Here is a table summarizing my acquisition:



Image scale is 1.13"/pixel FOV is about 4 degrees across

The abin link is: https://www.astrobin.com/ibkn1x/0/

However, the image there is a JPG since the uncompressed file is so big I cannot upload it there (limit of 25MB). I hope it is not too bad.


After doing this project, 10 hours integration time of a target seems...well...like a breeze.lol.gif


Enjoy. Or not tongue2.gif


NGC 292


P.S. Annotated version through PI. (Only the "big" objects, otherwise it will be impossible to read anything. Its just full of text!)

Beautiful image. So much to look at.  


I had the good fortune of going the New Zealand last November and coming from a Bottle 7 zone, I was absolutely amazed. It wasn't until I had gotten home that I realized that this this massive hazy/white patch seen in the sky with naked eye was one of the Magellenic clouds. Not sure if it was large or small but it was truly amazing to see.
