Nine Panel Ha Mosaic NGC3372 Eta Carina

[barx1963 (Malcolm)]

This is a Mosaic of 9 panels. Each has 5 x 5mins of Ha data, so total of 3 hours 45 mins of data. Mosaic capture was done in SGP with the Framing and Mosaic Wizard (which is now an inclusion in V3 of SGP BTW rather than a seperate add-on) and Mosaic was constructed with Pix Insight along with most of the pre and post processing followed by a bit of level and curves in PS CC 2017 and a some layer masking to bring out the detail around the Keyhole.

Equipment was:
Scope: Stellarvue SVR102T IS
Mount: Orion AZEQ-G
Camera: Atik One 6.0
Filter: Astronomik Ha 6nm
Guiding: Orion ST80 and Orion SSAG Pro with PHD2
Acquisition: SGP

Perfect pinpoints right to the edge. Spectacular shot!

Really nice Malcom, SGP does make it easy to make mosaics.
It looks seamless so very well done

A seamless mosaic, nicely processed and I can appreciate the effort involved! Did you use the dnalinearfit script before the gradient merge, or did it go together without any problems?
cheers,
Andrew.

That’s a beauty Malcolm although it looks like there’s some nebulosity trying to escape off the edge

Nicely done Malcolm. There must be a lot of work in that.

[Ryderscope (Rodney)]

Stunning effort Malcolm. Worth the time to capture the extra field of view that you don't normally get with this object.

Actually, this is the reference image I created with Star Alignment. When I went to make panels using SA to then merge with Gradient Merge. The panel didn't work on the second iteration, and this result was so good I just used it instead. No I didn't use DNA Linearfit. Just a bit of MLT noise reduction then a bit of tweaking in PS. I did have to use a repair brush to fix up a single seam in PS but was relatively easy.

Thanks Dunk. Yup, shoulda gone with a 16 Panel one to capture all the stray bits of Ha.

Well done!

Great start mal but you've decapitated Gabrielle's head!
Maybe add a few more panels at the bottom to balance the image
