My Bubble nebula

[jimao22]

Hi again,

I had 3 full nights on the row for astronomy and this is my second deep-sky object aimed.

I like bubble nebula very much and I will work more to improve these images in the future nights.

Set up - that from the signature (the AT8IN)

12 x 600 sec H-alpha 34nm

9 x 60 sec R,G,B bin 2

Stack in MaximDL, levels and curves in PS2.

That's a very nice Bubble!

Lovely bubble great job

Thank you!

Is not big deal. I have much more to learn, Anyway, I learned a lot doing this and if the time will allow, I hope to show you some improvements.

Wonderful - well captured

[jimao22]

Thanks to all for the nice words, but that was not so good image. This is good...

It was made with the Equinox 80/500 and Halpha filter 7 nm, 20 exp x 600 sec, -5 degree sensor, ATIK 314L+ camera and guiding with ORION 80/400 and ORION SSAG. The mount is EQ6 on EQMOD. Acquisition with MaximDL, calibration with 10 darks and then processing with PS2 - level and curves.

[Quatermass]

Both good but I like the colour version best.

Very nice capture.

Very nice bubble and cool Hertzsrung Russel diagram avatar:)

Well done with the bubble, it looks like you are learning fast

[Gina]

Very nice image

This is my try to Bubble from this year, with my new set-up (MN190) from my new observatory. 14 exposures x 900 sec each, Ha 7nm Baader, MN190 on EQ6/EQMOD, guided by SSAG on 50mm finder. Captured, calibrated and stacked with MaximDL, the rest with StarTools (great software !!).

The acquisitions are the same but the processing was different - one is showing the filament structure of hydrogen clouds and the other, the density of hydrogen clouds.

[jimao22]

And because I told you about StarTools and how pleased I am with it, I will show you a different approach using StarTools on the picture above, made last year with the Equinox, in Ha too. No other exposures, just processed in StarTools, same frames.

[jimao22]

Last night I made 13x900 sec exposures on same Bubble, with OIII Baader filter. I kept only 9 to be processed but I used a different path to do this, because with StarTools I didn't achieve great results. So, I did calibrated and stacked with Maxim, than levels and curves with PS2, than back to Maxim with Ha and OIII, combine colors, assigning Ha=R, Ha=G, OIII=B, than linear stretch in Maxim again, and here you have the result. If weather still good, some SII exposures will follow, to see what is happen.

Wow, fantastic capture.

Awesome!!

Jimao, 那很好看

[jimao22]

Jimao, 那很好看

Is that good?... Or is something awfull in Chinese?...

[Adamar98]

那很好看 means it looks good. He's right. Nice images.

[boris sputnik]

Tres belle photo ,félicitation !

Very nice picture ,congratulations !

[jimao22]

Merci beaucoup! Tu est tres gentil. C'est une essai, pas une performance.

I made the final job for this picture, acquisition for SII. The color was obtained same way I did it last time (for the moment I don't know other way to do this) - I made calibration and stacking for each channel, separate, in Maxim and than I used the "combine color" feature from Maxim to obtain an RGB picture. The problem was to "weight" the colors to obtain white stars, so I used StarTools and the "Color" feature of this program and pointing to a star (assuming it was a G2V star - I didn't check anyway), this happens asap.

Perhaps someone else have better way to do this.

I know I do have some artifacts on stars (from Ha aggressive processing) but I promise I will do my best in the future.

In case someone of you want to try, I can send the .fit files. My only request is that the result to be posted here.

Thank you!

Seeing these in the same topic, one after the other I realize now what a great improvement you've made from last year.

Great job Jimao

Great bubble
