  1. It is always hard to start up and know all what should be done as there is so much to learn. I am no expert in any way but there are some things that I can see on your picture. There are a lot of diagonal stripes all over you picture, this can be removed by using dithering which should be available in NINA which I never used. Dithering moves the scope a little bit between the images. I use Astro Photography Tool and have set the dithering to to move a little after every third image. This will eliminate the stripes completely. You as many others lives in a lightpolluted area if you don't have it already you should get a CLS (City Light Suppression) filter to your camera. I used a Canon 700D before and purchased my filter from Astronomik. The filter helps a lot. There are many dark blobs on the picture they normally depends on a dirty sensor on the camera. You can find special pads that are used for cleaning the sensor and they should be used with care. At least some parts to look into
  2. Taking some LRGB pictures this night. Saw this a few minutes ago when I was watching PHD2, a fast passing object made a white line on the screen. Checked the picture taken same time and here is the line. It does not look like an ordinary satelite line, this is irregular and you can see it becomes wider and smaller just like it is breaking up, it also seems a little wider on the top of the picture then on the bottom nnd I thought it was very fast Could this be some spacejunk burning when up passing the atmosphere? Any ideas? Picture is from the red channel. f/l=1000mm
  3. Caught this single shot yesterday (pic unedited except size) amongst many others on same objects as well as 8 video clips to be edited in Registax. After several hours of digital work I found that the very first single pic I took is the one I likes the best, "dont go over the bridge for water" Captured with Canon 70D and Skywatcher 190 MN
  4. This is a tricky one to capture, the galaxy seems like it has lost its gravity from the center and is ripping apart, guess that is an illusion as it is probably just faint Good job
  5. Thanks David I realized that I actually gave the wrong description on this one. I wrote it was NGC2162, my bad, it is IC 2162 nothing else, so no it is no montage.
  6. Thanks Jeremy. Of course I am not the first on this but I had never seen it before this day either so..
  7. New to me as well, stumbled upon it 17 jan actually, but do not remember from where I saw it. Rather small target so a larger scope and less lightpollution...
  8. Another target that is no so often seen, With some imagination you can see 2 nebulas in sequence on the way towards the more dim nebula. So why not, (NGC2162=wrong) IC 2162 "The journey" or "Snowballs"? I had a short window 17/1, 4 hours, aprox. 15x300 of each. (HA, OIII, SII)

    Thanks Roy. 6 Months sorry to hear, 2016 I started with astrophoto and I remember I could carry my equipment in and out so many times starting at september ending at the end of april. Last season 2021-2022 it took 99 days in mid december before it was time and same this season. If I had welded my scope on James Webb just before launch it would solve the problem It is as it is.

    Thanks Carole The starless version I thought was a better choice this time as it really shows the nebula, but as you say the stars are present in the real life, so today I gave star version a try with BlurXT As BlurXT makes the stars smaller they are not so distrubing as I thought they would be and it also turned out pretty well.
  11. The second image gathered 16-17 dec-22, around 25 pics each of 300 s HA, SII, OIII in total 75

    16-17 dec 22 I got a window in the sky, first this season. started with the elephant and ended with the rose due their time in the sky from southern Sweden which has probably the worse skies in our country. I wonder how long I will continue with this childhood love as the weather is no friend and getting worse every year it seems. However once in a while the results gives me what I am longing for. Learned a little more in Pixinsight handling and also did a new editing on the rose taken with the smaller 460 scope -21. 1000mm around 15 of each 300s bin1 460mm
  14. Hi Simmo In my point of view, both pictures are suffering from too much green. The stars on the HOO is too green and on the yellow version both stars and background is too green. On the yellow version you can also change the colors on the background, decrease the colors a little on the blue and increase a little on the red. If you are using Pixinsight and have Starnet2 you can extract the stars from the yellow version and put them on the HOO version instead I think this will give you nicer stars. I am no expert but I did a quick color adjusment on the false SHO
  15. You even got the tricky center on M42 right Nice piece of work
  16. Yes you are right, only I wish it was that easy with this tube I happen to own, no the main mirror has enough space to move if needed. Have recalibrated the rubber pads several times after I adjusted the screws reaching the main mirrors back and made marks in the mirror. Last time I opened it I could not adjust anything as it was lose enough already. Guess I have to live with it as is. I suspects one of the mirrors itself, but I am not in the mood of buying new mirrors. Thanks
  17. Took this a autumn 2020, been working on it now and then, got different results. The stars are manually digitally improved as my tube prefer giving moth like stars. The smallest and faintest stars are removed because I thought it was worth the efferod for the nebula. There are many small stars left, slightly larger than the ones I have removed. I guess more then thousand stars has been edit in one way or another and there are still more to do if you like, I have not drawn anything on the pictures that should not be there, just adjusted what already was there, I wish I could have less problems then the ones I am allready facing, but this is my reality and I do what I can with the pictures from my gear and transforming them into what they should look from the very beginning with proper equipment, so I must cheat or edit whatever you prefer to call it. Here is how most stars looked before they where corrected as my dumb tube think they looks And here they are corrected, (there are more to be done I know, there are still some moths) So spending some hours adjusting the stars and some editing on the main target gave me this result: I am happy with the final outcome and with the fantastic digital tools that allows you to do this, pure magic for me. 35xHA,SA,OII x300s No darks, bias, only Raw pics Sky-Watcher Explorer-190MN NEQ6 SkyScan Pro ZWO ASI1600MM Pro
  18. Adding another version ASI 1600mm SII+HA+OIII HA 36 x300, OII 20x300, SII 20x 300
  19. During three seldom nights 26-28 feb-22 was without clouds here in sothern Sweden I got my gear out. Normally there is a constant haze + a medium light pollution that does not make the hobby any easier. I gave the pics a new try today and found that the first of this three days was slightly out of focus or more haze? So a new alignment was done today using day 2 and 3 only. I have been doing this hobby since 2016 and with my bad luck was given this picture. The picture I got is hardly noise reduced, if at all, no darks, bias or flats has been used. This is the very first time I can show a full scale image from where I lives, of course the small bad sides is croped away on each side. ASI 1600mm HA+OII+OII HA 36 x300, OII 20x300
  20. Which guide camera do you use? The reason I ask is that I have ASI 1600MM and tried a short while as guide camera the ZWO Camera ASI 120MM Mini Mono, it worked just fine a few nights But then my pics went bananas, on the computer the guide camera intefered with ASI 1600 and the pics was totally lost, I have not saved any of the bad pics, but maybe this could be your problem? I do not use the ZWO Camera ASI 120MM Mini Mono any more and that problem is gone.
  21. "heavily cropped, minimal processing," was the moon lurking in a corner or it was not a clear sky as wanted, this is my own common issue, " I do see the stars, but are they visible enough"
  22. The giant champion is cheered by the crowd of the rose. Astro-Tech AT-65Q. HA 35x300, SOII 20x300, OIII 20x300 Bin1x1, no flats, bias or darks.

    A dark sky helps with the dust helps, I suffers from some light pollution and will never get the dusts, hopes you have a better site and will get what you wants
