Sh2-308 Dolphin Nebula Processing

I’m still gathering data ( Ha and Oiii ) on the Dolphin Nebula and would like some processing tips prior to completing the capture. This object is primarily Oiii with Ha accents Any suggestions on how would I load Compose to achieve a good narrowband composite ( remember there is no Sii ) that refle...

Re: LRGB or RGB?

Hi Mike, An interesting topic Gee this LRGB vs RGB thing has been thrashed around on so many forums over many years and I still don’t think there’s a definitive answer , too many variables involved and so subjective. However thanks for raising it in the ST forum. With my limited experience with Mono...

Re: NGC 3324 Gabriela Mistral Nebula

Thanks for your suggestion and advice As I mentioned I’ve had success with 1.8 HDR Tame which is similar to DSO core in 1.7 HDR However , I’ve tried to emulate 1.7 Optimise Soft ( and even Optimise Hard) in 1.8 HDR and it ends up unsatisfactory, it doesn’t accentuate specific structures and target k...

Re: NGC 3324 Gabriela Mistral Nebula

Thanks Mike, I’m sure SV Decon since inception has been a works in progress and can only improve for the next version 1.10 ( if Ivo has the time and motivation) In regard to coalesced white star cores , I've tried everything in 1.8 to alleviate them including adjusting dynamic range, can’t really so...

Re: NGC 3324 Gabriela Mistral Nebula

Hi Mike, Thanks for your comment Much appreciated After struggling for a long time with HDR and SV Decon in v1.8 , I thought to myself why not give 1.7 a whirl and see how it performs with Mono data sets. Whilst painfully slow compared to 1.8 , 1.7 did a great job on this image. My images are usuall...

Re: Astro to Astro-art Continuum, 2024 Edition

Dietmar , Absolutely brilliant !!! I must be showing my age The closest thing I got to electronics and computers as a young fella in my last year of high school was using punch cards in a mechanical encoder and building a Wheatstone bridge in the engineering class ( early 70’s) I didn’t get into com...

Re: IC 2944 Running Chicken Nebula in SHO

I saw an old YouTube clip on Startools ( Astronomy and Sailing UK about 4 years ago) where the chap used a final colour touch up in Canon DPP4 which seemed to improve the final image. So I decided to try DPP4 on my IC 2944 to see if I could tidy up some minor colour issues As the colour adjustments ...

Re: IC 2944 Running Chicken Nebula in SHO

Hi Dietmar, Thanks for commenting Yes the Oiii and Sii signals were very weak , in hindsight I should have compensated for that in my sub count , however I only get a small window of opportunity to image this object due to my house and trees etc… blocking its traverse The large star artifact was cau...

IC 2944 Running Chicken Nebula in SHO

Captured IC 2944 Running Chicken Nebula over 2 clear nights last week using my Mono set up for the first time on this target. I've imaged this object many times before but using a 2600MC OSC and Antlia Dualband filter. Unfortunately at my City Suburban location I have a limited view to the South Eas...
