Thank you for all the comments!

I have decided to stick this post in General Photographic Chat as I might get in trouble for this....

These are my astro shots taken over the last week, but not shot with a Pentax. I'll be honest... I have an astro modded Canon 600D that I use mostly, and that is what these have been shot with. I am pposting them as I really wanna show you guys what I am doing. I will do some with my K-S2, but won't be happening until I replace my Pentax mains power adaptor, which recently went kaput... This is becasue the battery life on the K-S2 is naff!

These are all stacked images of between 60 and 160 plus images. They were stacked and stretched in Siril, then PP'd in PS. I also used TopazAI Denoise to clean them up.

The two telescopes I used are an SV Bony SV503 70ED f6 Refractor with a focal length of 420mm. This also had a 0.8x Field Flattener on it. This reduces the focal length to 336mm. The next one is Sky-Watcher 150P f5 Newtonian Reflector with a Coma Corrector. This incresease the focal length slightly to 825mm.

All the iamges are shot using either a UHC (Ultra High Contrast) & CLS (City Light Supression) filters. I also shot extra images using Hydrogen Alpha and Oxygen 3 filters to bring out details.


These are shot thru the 70mm Refractor:
Andromeda Galaxy



Horsehead & Flame Nebula



Orion Nebula



Rosette Nebula



Veil Nebula



These were shot with the 150mm Reflector
Orion Nebula



Pleiades Star Cluster - Also known as the Seven Sisters

Fantastic image.... wonderfully caught

Last night over a 3hr period... My K3 and Sigma 150-500mm were pointed at the Orion Nebula.

This is a tracked and guided image.

2 and 3 for me...

The house reflected in the pond looks better in colour to my eyes.

Great work tho

I use LS & PS.... fair enough it's 10 quid a month, but I get all updates. Plus it's simply the best. I've tried lots of other stuff but they are just not as good...

Topaz are well worth the money.... but dont push them to hard or they'll look false.

I use Topaz Denoise most, and leave it to make up its own mind. Only now and again does it need tweaking down slightly.

The first one has me captivated

Loving the last one, but they're all brilliant!

These are brilliant!!
