Pacman in narrowband

[OriolLehmkuhl]

Hi folk!

This image was taken on different nights (november 1,2,3)on moderately light polluted skies. We have taken 12x 10 min with 7nm Ha Baader filter, 8x20 min de SII and 6x15 de OIII. The images were calibrated and registered with ImagesPlus and stacked with MaximDL. The process was carried out completely by using PixInsight STD.
We have used this time a different combination proposed by Juan Conejero in a tutorial of PixInsight [SII+Ha*0.78]OIII+0.15*Ha[OIII]. We hope you like it . Comments are also welcome.

Hola Ivette & Oriol

A very nice image. I definitely like it in all respects. Much better than your previous version, in my opinion.

Don't you think that the red/orange/cyan palette yields much more credible images than Hubble's one? Talking about narrowband images, the choice of a particular palette is of course a matter of personal preferences. Hubble's palette is ok, I just think that we can explore different approaches.

Did you apply some deconvolution to this one?

Best,
Juan

Hi Juan, thanks for your comments.

We think, as you, that the red/orange/cyan palette yields much more credible images than Hubble's one. The Hubble palette is really nice, but in our opinion tends to give too much prominence to green.

Did you apply some deconvolution to this one?

We have implemented a slight deconvolution to the luminance, but the parameters of regularization have not been totally successful (even so, the image has improved in resolution details ). But we will continue trying   :wink:

Regards,

Oriol and Ivette
