Hi Dietmar, Thank you , I don’t know about perfect but a pleasing result. The SHO has a bit more contrast in the shadows and highlights but the Synth LRGB is a nice option to have and present too. Looking at some images in our local forum where the object was captured at really low altitudes you can...

Captured over 4 nights during March during the Full Moon period, here’s an SHO narrowband image of the Carina Nebula’s eastern region which is one of my favourite areas of this magnificent nebula.

Thank you !
I just followed Ivo’s advice a while ago on using SHO narrowband data and process it like an LRGB
Result was pleasing
I’ve used this method on a few other projects , again with good results.
Another useful tool in the Astro tool box

Due to imaging under Bortle 8 light polluted skies with clear nights during a new moon period rare , I use a niche process in Startools via its Compose Module to create visual spectrum synthetic LRGB image from my acquired SHO narrowband Data set. Here’s my recent version of NGC 3324 Gabriela Mistra...

A rare treat this late summer , 4 mostly clear nights within one week plus the tail end of the new moon. NGC 3324 was nicely placed just clearing my neighbours tree at dusk. Seeing and transparency were good and a stable upper atmosphere resulted in tight guiding. Bortle 8 City suburban skies Humidi...

First capture of IC434 the Horse head Nebula in Ha LRGB at my Observatory under B3 Skies. Captured over 4 short nights ( 28th and 29th December 2024 and 21st and 27th January 2025 ) Summer so far on the East Coast of NSW has been plagued with cloudy nights with very limited windows of opportunity fo...

Summer so far has been mostly cloudy with only limited opportunity to image and poor seeing conditions. Captured a couple of hours on IC434 Horsehead Nebula from my NexDome Obs on the South Coast under Bortle 3 skies. Managed only some Luminance and Ha data over two different nights as the cloudy we...

Captured M42 Orion Nebula last week over 3 nights during the New Moon period under my B8 City suburban skies. Its been just over 2 years since I last imaged this spectacular celestial object. I chose Narrowband in lieu of Broadband to see how the 2600MM and Antlia 3nm filters performed with shortish...

Wonderful image of a porthole into the Universe
So many distinct and faint galaxies from corner to corner
Certainly stirs one’s imagination looking at these types of images like a quote from Plutarch “ The mind is not a vessel to be filled but a fire to be kindled”
Well done indeed !!
