Another pearly whale thing - NGC55

[Benjamin]

Just adding this LRGB take on NGC55. Captured while testing out a MeLE Quieter3 mini-pc running Windows 11 and a new GL-Inet “Mango” Router. Both these things worked great, but the Newt needed some work.
Skywatcher CF 8” Quattro f4 Newtonian
ZWO ASI1600MM-Pro (Gain 76 -10°)
Skywatcher eq6-R
Astrodon LRGB, about 5 hours of mostly 30” exposures.

those stars look pretty good to me! i'd say you tamed the quattro's collimation pretty well! great colour depth too on such a short integration, well done once again!



i got one of those mele minipcs as well recently, they're really great hey? super small and easy to mount, and 1/10th the cost of a primaluce eagle :P

That’s lovely! Great colour and super smooth. :thumbsup:

Ended up using the stars from only the last of the three nights I spent imaging this, when I’d finally corrected for tilt. Still not perfect but have a feeling the old Skywatcher Carbon Fibre tubes aren’t the greatest for holding everything in place. The MeLE has been great although my old TpLink travel router refused to play ball. The newer and tiny GL-iNet “Mango” travel router not only works but I get network signal over much better distance.

Cheers. Galaxy and LRGB imaging are always a bit iffy with my sky conditions and gear so very happy to get something on this.



Thanks Dave. I had an interesting journey with noise on this with some large scale patterning that I think came from flats poorly correcting as I didn’t take the flats with my newly made light shield applied. Had to isolate and correct that noise first then used a relatively new tool: NoisExterminator. This tool hasn’t worked on some images where the detail is multi-scale or lurks delicately in the background, but did seem to work out well on this object.
