Retun to the Rosette after 6 years, in HOO

[The Admiral]

The last time I imaged this object was six years ago, using Alt-Az imaging, a Fuji camera, and 102mm APO. I've not been very prolific in the intervening years, but I now have lighter weight gear, an AM5 EQ mount and Askar FRA400, and am learning to process dual band images.

Here is an HOO rendition of NGC2244, produced by APP and finished in Lightroom. There were 54 x 3m subs (2.7hr) with the ASI533 and Optolong L-eXtreme. A series of darks, flats and dark-flats were also taken. During the sequence I was plagued by cloud!

 

 

Thanks for looking.

Thanks for posting this lovely image Ian. I particularly like the colour combination you have employed in the final image. Can I enquire at the Bortle level in which the data as collected?

Cheers,

Thanks Steve. Somewhere between 4 and 5, nearer to 5 I guess. I don't measure it. Given the amount of cloud passing through and the interruptions with guiding, I suspect that transparency wasn't great.
