That's very nice.  24 hours is about 6 months worth of evenings over here in the UK !!

How do you find the 294mm ??     I'm tempted by one  ( and I have a SW10" Quattro as well, so your photo is very encouraging).

I read a lot about "banding" issues which is putting me off.

Sean.

No banding issues for me whatsoever. It's a perfect camera paired with the Quattro. I don't hardware bin 2x2 Bcs it does make things look a bit grainy. I shoot full resolution with all of my scopes (max Fl 1000). If you want to bin, I would highly recommend software binning. Other than that, this camera is awesome. I love how much detail it captures with the small pixels 

Hey Everyone!

I've avoided mosaics due to the single fact that I know how much exposure time I like to put towards a single-frame image.. I would have imagined that this photo would consist of 60 hours or so.. Alas, this image consists of 24 total hours of data! I collected 6hrs of data through my 3nm Ha/Oiii filter per panel This was a learning experience but has also gave me confidence to attempt this again with maybe something a bit larger! I hope you all enjoy this supernova remnant!

Nicely done with lovely colour and detail in the nebula.   Super.     If I may say, it would be A1 if you could correct the star colours.  It is often worth shooting 8 x 2 mins in each of RGB and using the stars from that to replace the ones in the image from the narrowband filters.   There are techniques to do that in PI or Photoshop.

Yes.. I will do this. I typically shoot RGB stars and replace them. The method is very easy.. Shouldnt be too hard to do. I can starnett, clone stamp the halos. layer in the RGB stars. 

Hey Folks!

Despite having several clear skies.. the smoke from the fire out west have ruined many chances of gathering data.  I did mange to gather about 20 mediocre hours of data through all the smoke and haze. Unfortunately, my Oiii channel got hit the worst hence the halos.

This image of the Sadr Region consists of 20 hours (8/6/6 HSO) of data taken from bortle 7 skies. I hope you enjoy!

(Slightly crackers 😉) Dedication paid off. The gas bubble really seems to have depth. I imagine the processing time was huge too?

Congrats. 👍

Thank you! Yes processing this took some time! It took about two weeks to really settle on a final result!

Fantastic result.  Wow 40 hours, you must have much better weather than we get here.  Also great for Bortle 7.  Gives me hope at Bortle 8.

Thank you , Carole! YES.. with 3nm filters.. anything can be done! muuahahahah

Hey guys!

This post has been a long time coming. After considering an 11" edge Hd, an 11" Rasa, or a completely newt Parallax 10" Newtonian.. I have agreed to save a couple thousand and just fully upgrade my current 10" Sky-Watcher Quattro. 

I have decided to go for a fully motorized FeatherTouch focuser along with rotating parallax rings. The stock rings are a joke and are meant for a vixen dovetail. Not happening. Lol the stock focuser just sags and slips way too much for any desirable result. My ZWO EAF Hardly works with it anymore..

All that being said, I'm wondering what other nice, top of the line upgrades anyone with expletive here may recommend!

At this point, I'm up for anything.

Thanks friends

I'm not sure about smaller pixels though. In my view image is still over sampled.

What is your original pixel scale - somewhere around 0.5"/px?

I'd say that your image has resolution of about 1"/px - which is still exceptional, and data goes really deep.

I imaged bubble at 0.5"/px as well - but did not leave it like that, opted to bin x2 for 1"/px, however, mine has slightly less resolution compared to your image and your goes much deeper. I did it with 8" RC scope and Heq5.

Here is a quick comparison of the two at 1"/px (btw - notice very similar SHO processing)

Your obviously goes much deeper - just look at detail in nebulosity and it does have slightly higher resolution. It might not be apparent straight away - but look at spikes on that bright star - they are slimmer in your image - which means that star jumped around less and has smaller FWHM. To some extent, this can be seen in the stars as well - yours look tighter - more pin point.

In any case - this shows that no detail is lost when imaging at 1"/px really, so I don't think that pixel size played a part - but again, I might be mistaken there.

 

 

I think that you are likely correct in that I am and always will be a tad over sampled at .50". My seeing conditions dont support this resolution. I did see somewhat of a difference in resolution between my asi1600 with my newt and my asi183 and my newt. That could be differences in processing, seeing conditions, etc. There are too many variables to compare my two images rigs. I now have the asi294mm (2.36um) which I use for my newt and my smaller refractors. This seemed to be the best camera option for all of my scopes.

This is really sharp and detail is very good.

I must notice that not only sky but 10" and CEM60 are components needed to capture such high resolution detail.

The large aperture and smaller pixels really help to hit those smaller details. Especially with a fast scope

Hope you don't mind me saying but there is a really easy way to fix magenta halos in PI.

yEs, I typically invert and SCNR green but that also took the magenta hues away from the central region of the bubble which I did want to keep. I could have made a mask and uploaded it into Photoshop and adjusted the mask even further but It wasnt of too much concern for me. I dont typically like the magenta stars but for this image, I didnt mind them at all

Just now, Adreneline said:

I really like the almost 3D nature of the Bubble.

Can I ask which processing software you use?

Adrian

Thanks Adrian,

For this photo, I used PixInsight only! I typically go through Photoshop for further noise reductions or color correction as well.

Greetings Folks


I have been eagerly waiting the rise of the Milky Way. I cannot handle shooting galaxies in bortle 7 any longer! That being said he is an edit of some older SHO data collected early fall of 2020 right outside of Cincinnati, Ohio (B7)

The Bubble Nebula - This is, and will likely remain the some of the best data I'll collect for the foreseeable future. My seeing conditions were spectacular during the three nights of capture and the data acquisition process was flawless allowing me to get the best out of three full nights. My goal for this image was to capture the internal star forming region within this nebula in some detail. The Hubble view of this nebula really inspired me to kneed out the details best I could. The nitty gritty is what I am about when it comes to astrophotography and I tried my hardest to preserve it. I I really hope you all enjoy!

Greetings,

Moving back to the bortle 7 skies of Cincinnati from the dark skies of remote Colorado has brought back old challenges.. So, I've been rather nervous to try and shoot an LRGB target from under such skies again. I suppose I chose a rather easy target to conquer under bortle 7 skies but I had to warm up before I start shooting galaxies again.

I am rather happy with these results. I gathered a total of 34 hours but stacked only the best 60% to rid myself of of images with clouds, haze, branches etc. This is a total of 21 hours. I was pleasantly surprised buy the amount of fainter dust I was able to pick up. I would be very curious to see if I could pick up the dust in the surrounding area with a full frame camera. I am also very fond of this doublet I shot this with. It has finally allowed me to shoot this target as a whole for the first time! 

Anyway, I want to show that with enough exposure time and post processing practice, one can take a passable image under suburban skies. Let me know what you think!

Cheers

Hi Everyone,

I hope everyone is having a great weekend so far! Here is a photo I have finally processed to my liking. I collected this data very early this year in Pine, Colorado under bortle 4 skies.

The Coma Cluster:

The Universe is just a bit bigger than the world around you. We live in an era when people forget to look upwards. They forget to look upwards at the vast environment that surround them. It spans onward for infinity. Looking to the skies, simply said, puts us in our place. Do not fear the vastness. Let it override your senses with awe and wonder. Do not fear it. Let it instill a sense of peace and a sense of rarity. We are so extraordinarily lucky to have the ability, as conscious beings, to ponder this universe. We are such a tiny blip in the grand scheme of things...but we ARE here, and that's pretty damn cool.

Below is a picture of a very large structure. This is a cluster of galaxies that lies 322 million light years away in the constellation Coma Berenices. There is well over 1,500 galaxies in this image Which I took from my backyard. A galaxy cluster is one of the largest structures in the observable universe. All of these galaxies are bound by the immense gravitational force of the central cluster. You can see a couple different types of galaxies in this image such as Spiral and Barred Spiral galaxies as well as elliptical galaxies.

Over 1,500 galaxies. Each of these galaxies have over a 100 billion suns and some up to nearly a trillion. Many, many of these stars are hosts to a planetary system. Many of these planets are likely orbiting around the habitable zone of their sun. Many of them probably have life.

I hope you all enjoy!

Hey Everyone!

I hope everyone is having a great week/weekend so far. I have been lucky enough to have 5 clear nights in a row! I was finally able to test out my new asi183mm with my 10" Newtonian. I traded my asi1600 for the asi183 has it paired really well with my newt for a really nice high resolution imaging rig sitting at .50"/pixel.! It will also pair really well with my refractors.

For my first image I chose to shoot the Bubble Nebula. This one has always been a favorite of mine, especially with longer focal lengths. I gathered a total of 34 hours on this one. These are rather large crops as I am still working on the widefield versions. I've always wanted to capture the central star forming regions. Such a fascinating object.

Below are two version, one in the classic SHO Palette and the other in a orange/blue bi color palette. Both images consist of all three filters. I cannot much decide which I like more.. creative decisions.. I hope you all enjoy!

Clear Skies,
