That's Nice! Yes, It was a very short integration time. Had a short night, and had to delete lots of images due to objects in the foreground. And my camera isnt astro modded (Don't want to risk anything). That's the part of the milky way I wanted

I don't have any reference images of this part of the border between Scutum and Serpens to compare with but looking at the raw stacked outputs from Siril and DSS I suspect you have some stray light contaminating that part of the field, possibly the moon, or light pollution etc., but stacking artefacts will also create a fuzzy glow in parts of the field where star matching is poor.

More data is always good because then you can selectively reject the poorest subs from the stack and only combine the best frames to give a clean image to begin post processing.

There are many tools in post processing to cleanup a poor stack but it is always better to have the best quality starting image possible before beginning to stretch and enhance the image.

Hmm, Ok. Thanks!

This was the quick and rough result I came up with for the Siril output, basically the same tools and processes that Wim used in PixInsight for the DSS file.

Always find it difficult to process Milky Way images of this scale with very few empty background areas to get a reference for gradient removal plus the horizontal banding that always lurks in the images from Canon cameras begins to show as the image is stretched in the dark areas after gradient removal is applied.

Could spend hours on this data set to get a really good result.....

 

Thats Nice. Why is there weird stuff happening in the bottom side? Is it not enough data when stacking? 

No manual focus?

Thanks Elp,

I did some of the same things in Siril too. But I was unfortunate, and caught a bit of a tree on lots of my photos, so I had to delete half of them  . Also a short night didn't help.

And you can see the nebulas much clearer 

Wow, thats still very good. If you have time, try the Siril one with some old flat frames. I think Siril does a better job at fixing small issues like that.

Thanks, I did notice too that mine has the two nebula more visible and red. I think with me understanding more about post editing, I think I could still make a nice photo.

Thanks Olly.

Thanks Everyone btw, It was all very helpful 

Hi guys, 

Sorry for not responding. Sorry if I was not being clear, but I was struggling to edit the photos in Gimp, and turn them into a nice photo. I had a go my self, and then got someone else to try, and they did a pretty good job.

This is my attempt:

This is someones else go:

Hope Thats What You Wanted.

Here are the three:

DSS:

Siril With Flats:

Siril Without Flats:

I can try, But they are just stacked and dont look good. Give me a Sec.

Sorry, I Didn't Think of that 😅

Hello Everyone!

I had my second semi successful night of taking photos, and I took 26 photos of 30 sec exposures on my Canon 400d, with a 18-200mm lens @ 50mm. It was at ISO 800, and at f/5. I think I have stacked the photos correctly, and tried Siril and DSS for the stacking. However, the Siril one does not look right. If anyone can have a go, or point me towards somewhere where I can learn, that would be great.

If you have any questions that might help, Please ask.

Stacking With DSS

Stacking With Old Flat Frames In Siril

Stacking Without Flat Frames In Siril

 Yea, someone else recommended me to take photos with a shorter focal length, so im going to see how the tracker works with that. Thanks.

Hi, thanks for the reply,

On reddit, I found out I was properly polar aligned, and it was more of a mechanical issue instead.

Thanks for all of this. I will definitely try out some of these ideas!

Thanks Viaiv for the reply,

I have attached an image to here of a 30 sec exposure with the tracking on.

Hello Everyone,

I've just started my Astrophotography journey, and I've decided to build a DIY barn tracker which I 3D printed. I can't seem to get even a 30 second long exposure without star trails. The big wheel spins once every minute, which is correct, and I'm pretty sure its polar aligned, as when I put my phone with Polaris in Stellarium, it aligns up with everything. Maybe Its not orientated the right way or something. I have attached a photo of the set up, with north being straight on, and east being where the arm is pointing to. I am located near Chichester in the UK if that helps.

If you need more details, please ask and I will try my best to respond.

Thanks in Advance!

Here is the Tracker Set up

I just had all the stuff laying around from a long time, so I didn't buy anything specifically, except some memory and a remote timer. 

Thanks 900SL and Elp for all the info!

I will have a look see if I could make a diy tracker or get a different lens.

Btw, here is someone's attempt at editing the same stacked image I had

Thanks for everything everyone !!!

silly me 😅

Btw m31 gets higher in the sky over the next month or two, so you're fighting a lot more horrible atmosphere to image.

I'm new, and desperate to image m31 with my new gear, but it's still too low for me right now.

Having said that, it's probably ideal to practice and get data to practice with

Isn't the higher it is the less atmosphere there is, and the lower it is, the more atmosphere? Its always good to practice.
