I managed toadd a little bit more data to it. I think it's quite an improvement over the original. Managed to get some detail and colour in some of the little fuzzies too. 😁 Here's the astrobin link https://www.astrobin.com/lbnn92/

Thank you. I originally did a Photometric colour calibration in pixinsight on the RGB stars. That gave me a pretty good colour from the start. The background didn't look great but it really didn't matter as I was only gonna use the stars from that blend. After that I flattened the background using GradX in photoshop, blackened it and added the Ha as the red channel and 10% luminance. Increased the overall saturation and with a blurred inverted star mask, I applied a few iterations of Noel Carboni's Increase star colour action. Some of the stars had a purple hue so I took it into Camera raw filter there I changed the purple hue to blue. Emil

After seeing on the web a nice cluster from the southern hemisfere with a lot of backround Ha, I had a zoom through stellarium to see if I can find a similar one that I can do from my back garden. It didn't take long until I found the NGC2112 cluster that sits very nicely inside the Bernard's loop, so I went for it. Originally I only shot 15x300sec Ha but that didn't give me the details I was after, so I added another 3x300sec and 13x600sec in the hope that I could get some structure in the hydrogen alpha cloud. Even with this amount of Ha the details are not as I was hoping so I presume that it won't be getting any better if I add more to it. NGC2112 is a 9th magnitude medium sized open cluster located 4 degrees northeast of Altanik, the east star of Orion's belt, 2800 light-years away from us and it contains about a hundred stars. The cluster is being on top of the Barnard's loop covering the eastern region of Orion. With an estimated age of around 2 billion years this relatively loose cluster lies in a fairly rich field and most of the stars are faint. In a 6-inch scope, look for a smattering of only a few 12th-13th magnitude stars.

Thank you guys. I think I'll keep adding to it until I get close to around 20 hours. I try to shoot the luminance when the target is at its highest and the streetlights are turned off but I think a good light pollution filter would help a bit more. Maybe some 300sec on the RGB too. Emil

I found this and indeed with a 1.13 redshift it workes out at 12Gly http://www.astro.ucla.edu/~wright/CosmoCalc.html

Thanks, I'll try to add more to it and see what else pops out I didn't actually calculated it myself, I found it on this website https://astrovirusblog.wordpress.com/2020/05/17/m106-quasars-and-cosmological-distances/?fbclid=IwAR2_zqXun40oGqzGSfIq6WAYHrLJO2UdBd5VefqWLa_8Sj88K37JUDFBQOMhash=59fa4c9a54d59330b10735ae0c945b05#comment-699hash=59fa4c9a54d59330b10735ae0c945b05#comment-699 It was showing 15bly under the photo, I messaged the owner and it looks like he rectified it to 12 bly. It's saying that it has a 1.13 redshift. Where do you get your data from, I would love to know. Emil

Thanks. I could've probably done with a bit more data on it, being under bortle 7 skies, to be honest but I was so excited to see how it looks so far that I decided to stack and edit 😁 Emil

Hello again, As the galaxies are starting to get higher in the sky, I started to point my telescope a bit more towards them. The first that I can say I have enough data to produce a decent image is M106. Because @wimvb pointed out that my M97-M108 photo had some objects that are very far away, I took the liberty to go online and try to find how far some of the objects in this photo are. I was quite shocked to find that I captured a 19.5 magnitude quasar, 7C 121446.70+472852.00. I added it in white writting to the annotated photo and I also cropped a part of the large photo to show it better. This is by far the furthest deep sky object that I ever imaged and also in the crop photo there are a few galaxies that are more than 2 billion light-years distant.

Thank you! Quite a few people told me that I must have the best eq3 in the world Emil

Thank you Peter, indeed they are pretty something, I love mine 😁 Emil

Wow, thank you very much for the info, I never had in mind that I could capture things sooo far away with my little TS65Q 😁 Emil

Thank you! Yes, it is a pretty nice planetary nebula isn't it? Quite recently I've seen a photo of it shot with a much longer focal length telescope and it looked incredible. It even has a very faint outer halo that was captured very nicely 🙂 Emil

Quite recently I sold my narrowband filters for my OSC camera to fund an upgrade and because I'm only left with the broadband light pollution filter, I felt like shooting a galaxy, but I when I was zooming through stellarium I thought that a galaxy and a planetary nebula in the same photo would be nicer so I stopped to M97 - M108. This is a crop from the wider field of view photo. I drizzeled the stack x2 and cropped it to match the fov of my ASI294MM on the AT106 in case I will add some luminance to it at a later date.

Thanks. Indeed a bit of contrast on the original might change its overall look and make it more appealing. In the new one I used a star reduction script that seems to work quite well on some photos. I tried the starnet star removal but couldn't get a nice finish, way too many stars that gave me a very dirty finish, even after tweaking it in photoshop to remove the leftovers. Regarding the colour, I also tend towards the new one but again it's a personal taste 🙂 Emil

Thanks, that's exactly what I thought about the original one too 😁 Emil

Lately I've been looking at the photos that I shot since I started and I decided to try and redo the ones that I'm not really happy with. I learned a few new things over time and I'm trying to see if I can use them to improve the photos. The first photo is the result that I got yesterday and the second is the original attempt. I find the new one to be an improvement over the original but I would love it if you would give me your opinion.

I made it a wallpaper too Thank you. I was quite surprised myself to be honest. I think I chose the perfect target for my first light Thank you I got to use them the night after I got them , I can't believe how lucky I was to have a clear night Emil

Thank you Martin! Indeed the ha and sii flats look horrible. The flats with the Ha filter on the 294MC were very similar to what I'm getting with the mono and it took me quite a while to find some good settings for the flats to correct properly so I applied the same settings to the mono and it works great. I'm aiming for a mean ADU value of around 25k and an exposure for the flats between 2 and 5 seconds. This works great and the stack came out very clean. Emil

Thank you guys, I'm really glad you like it and appreciate your kind words. Well, I guess not 😁 Who can say no to chroma? Alastair was too kind to sell them to me 🙂 Zoltan wasn't very happy when I told him. Did you get yours yet? He rang me after I told him I won't get them anymore and he said that he has the Ha and Sii but the Oiii will come at a later date? Emil

No, I'm not planning on using the bin 1x1 on my main rig as I would be greatly oversampled and my seeing is not that good. I might use the bin1x1 for my lenses though. I sit very nicely at 1.38"/px with my AT106 and I love it 😁 Emil

Thank you John, I really appreciate your kind comment. 😊 Emil

Very nice Brendan, I love it! 😍 Emil

Hello guys. First of all I would like to thank @ampleamp for selling me the incredible Chroma filters that I've been dreaming about since I started mono imaging. This is the first narrowband image that I produced with these filters and I want to say that I'm absolutely in love with them. As my first target I chose something that I always tried to get a good result of, but didn't quite get something that I would be pleased with. Now can finally say that this is it, I've done, it and I love it. So here is the Rosette and the beautiful animal parade. The total imaging time is 6 hours , an integration time that I never thought could produce something like this from my bortle 7 back garden. 39x300sec and 1x600sec Ha 10x300sec Oiii 10x300sec Sii all with a ASI294MM and my AT106 triplet refractor at 690mm f6.5 I'm very pleased with the result and I hope that you will like it too. Emil

Thank you so much. I'm really glad I posted this because it shows that even though I was starting to think the data wasn't really good, after 2 years of learning new things and tricks I managed to bring it to a pleasant results. Emil

This time I started the photos in pixinsight and applied the noise reduction while still in linear state. After the initial stretch I reduced the star size in the Oiii and Siii shots (being my first narrowband image, I didn't know how to use the camera and I used high gain and long exposure giving me very fat stars on those 2 channels) and only after that I combined them into SHO. Photoshop is still my main editor and I do use Annie's action tools (always as a layer to be able to control a bit the overall result) but what you said make sense and I will give it a go in the near future, thank you.
