An excellent video Gav, very worthy of the praise in this thread and no doubt took may hours of hard work. Terrific 👍

WO 132 ZWO 178MC ADC x 2.5 P/M

 

I have been meaning to experiment with planetary imaging for some time and your Jupiter images using your WO FLT132 have given me the final encouragement - thank you!

I have just bought a second hand ZWO ASI224MC as a low cost/risk entry.  I am now just contemplating the TV 2.5x or 5x powermate along with an ADC, perhaps the ZWO one.

I am favouring the 2.5x as a more versatile tool along with being conscious of sky and scope limits.

From your experience which would you recommend?

CS!

Barry

Your latest revision Rodd is very good, with some fine detail in the Ha jets emerging.  Well done, good job!

CS!

Lovely image Ola - delicate and confident processing.

Lovely wide field and surprisingly deailed view of the Rosette.  Very sharp optics on the Canon lens too.

I agree that for this target there is always room for one more ?.

MURE denoise only works on a linear image that is an integration of your subs, a mono image from one channel. 

From how I understand it, If you do anything to that image, crop it, DBE it etc, then MURE denoise won't work correctly. It needs to be the first process you perform after image integration. 

? - that's correct.

That is an excellent mosaik Barry. Impressive! But, I am a bit confused about the breaking wave. Not sure where it is. You say the vesion on Astrobin is rotaded to show it better but it is not rotated.

Thanks Goran. Versions B and D on Astrobin are rotated 90 degrees.

In this orientation Gamma Cas is at the ‘top’ of the vertical frame and the Ha sweeps around the star in an arc ?.

Wow! How did I miss this one?! 

Insert a collection of adjectives, positive in nature, here ?

Why do I like it? The handling of the star of course, and it's apparent illumination of the surrounding ISM and nebulosity.

Great work ?

Cheers David . . . the dark skies at e-Eye really do help with the faint stuff.

Very moody rendition Barry, lovely job. That's certainly some marathon, both of data collection and processing! Interesting to see that you have both Ha and Lum data - do you mix them for the final Lum? For recent projects I have been creating a SuperLum in APP using all subs - it seems to be working quite well. Interested to know what your approach is.

Thanks Gav.  In this instance the two channels were kept and applied separately.  I have and do produce a blend of Lum and Ha using PixelMath, setting the output for greyscale, but it all depends on the target and the contributions of the two channels, as you'd expect.  Ha can sometimes create havoc with delicate blue reflection nebula and one goal was to retain the RGB combined blue in and around the Ghost.

This is a very nice mosaic, Barry - so much going on and well worth the effort you've put into it.

Much appreciated Steve - your Esprit 150 would  make a lovely Ghost (if you haven't imaged it already).  A four panel mosaic or larger is still an undertaking even when you have a greater frequency of clear skies; planning when to collect Ha, when to collect the Blues etc is all important if you are aiming to stretch your technique.

I am pleased to have completed another goal with this 4 panel mosaic of the Gamma Cass evocative nebula "The Ghost" and the surrounding Ha nebula that wraps wave-like around the beautiful blue glow of Gamma Cass. I was inspired after seeing Olly Penrice's image back in 2017, here.

Steve and I have persevered with weather since late October 2018 to bring together 88 hours of data. A marathon processing evening yesterday gave me the main image with finishing touches after work today. We have a vague notion to fill out the mosaic and to connect to NGC281 . . . but not just yet thank goodness.

On my Astrobin page I have also posted a rotated version to better see the "Breaking Wave", https://astrob.in/385005/0/.

Thanks for looking & enjoy the full resolution and the sharp optics of the Tak FSQ106.

Details:

• Tak FSQ106 at F5
• 10 Micron GM1000HPS
• QSI683wsg-8 with Astrodon filters
• SGP & PI
• Ha 84 x 1200s; Lum 144 x 600s; RGB 74 x 600s each

Yes, I have.

Without reducer at F5.3 I have a flat field.  With reducer I get 3 perfect corners and my top left corner (as viewed on my monitor) has a small amount of tilt.  Endlessly tweaking the 3 grub screws on the reducer has never fully removed it but has reduced it to a small fraction of a small tilt!

I have replaced the grub screws in the reducer, drilling out the holes and replacing with larger diameter caphead screws: this helped deliver more control to the adjustments. I have removed the CAA and examined it but not been able to make any adjustment with it.  My top-left tilt is small and not readily noticeable except by me.  My last tweaking gave an almost perfect field until I decided to rotate the ccd for framing and back came the small amount of tilt.

I have taken the plunge and bought the 3" FT focuser with tak adapter from Starlight but not had it delivered yet.  I am hoping that this will deliver perfect results!

Awesome Olly and Tom, in the original meaning of the word.  Stunning - visually and in combined dedication and effort.

Barry

Breathtaking and awesome image.  Incredible detail, wondrous!
