  1. ASI1600mm cool

    Same here. No astronomical darkness between April 21th and August 21th. Working on getting my observatory ready for new (second) season
  2. Observatory 17b

    The images from my remote observatory. All images and info is also on Observatory 17b
  3. M66 group (Leo triplet)

    For some reason I made some changes to this image on my laptop before posting, and tought the background looked to bright, and brought the blackpoint down, but then it ended up way to dark on my other monitors. Re did some steps and kept the background where I normally would, color calibrated the image (it's rgb after all!) and shrunk stars a little more. I do like the new version better on most monitors, but it does raise the question again of what monitor is properly calibrated? (I guess none as I use the windows wissard ) Feel free to let me know if the changes where in the correct direction. Especially the blackpoint.
  4. M66 group (Leo triplet)

    I did not notice that I added all the noise with a unsharpmask to the dso. I tried a TGVDenoice to the dso's and a unsharpmask to the cores, and it seams like it helped. The binning is not really needed. As you say it's done in software, and I could probably have done the same in post. It did however decrease the file size from ~31MB to ~8MB, so it did download faster from my remote obsy. Thanks. The noise should have been dealt with now
  5. M66 group (Leo triplet)

    First post in a while, and my first mono LRGB image. Camera Zwo asi 1600mm-c All images @ -30c and Unity. RGB binned. L 45x 300s R 24x 225s 2x2 bin G 16x 225s 2x2 bin B 5x 225s - 11x 300s 2x2bin All in all ~7h 30m Calibrated with bias and darks. I tried imaging this last year, but made a mistake in goto, and missed NGC 3628 Let me know what you think of this. Tips and feedback always welcome

    Hi iapa. The f number is focal length / aperture, so smaller numbers are faster. A short wide lens can be down to f1.2 or so, while a refractor is more usual @ f5 and up.
  7. SHO monkey business

    So here is quite possibly the final version. I used DarkStructureEnhance at ammount 0.30 on a clone. Then I cloned the original and added a dso mask to the new clone and used PixelMath to blend in 40% of the edited image. I have not used pixelmath to blend images before, but i used (original*0.6)+(edited*0.4) and dropped that process over on the masked result image. Then I used MLT on a new clone with 6 layers, and blended in 20% to a new result image. All in all quite happy with this project. No I just have to find out how to get more detail in my images. Mine do often seam a little out of focus compared to the really good ones posted here

    I'll have a look into that later tonight
  9. SHO monkey business

    So now I have made a version that I do like a lot. I did not do much, and used very low amounts on all the tools I used. Started off by masking to only reveal the dso. Then applied a Local histogram equalization. Added some more saturation, and removed the mask to add slightly more saturation to the entire image. Then I added a star mask and ran the process to shrink stars by an amount of 0.4 Let me know if the changes made it better
  10. SHO monkey business

    Thanks for the feedback I have been trying to stop my processing before I over process lately. I find it a better work flow to stop early and then rather go back an add to it later. I can see the clouds are actually clearing. Wonder if that lasts. Off to dso-browser and see if I can find anything bright and fast, or I might start on the LRGB Leo triplet I've been thinking abut. I was off target last year with my dslr and made a Leo doublet
  11. SHO monkey business

    Hi folks So this is my first full color nb image. It is the Monkey head nebula shoot between 13th Feb to 15th March. It has been so much cloud and fog here that I actually used a month to collect 11h 35min of monkey business! Its my first attempt at HST, and first > 10h image I have not got to try to finish with the processing, but I have calibrated, stacked and combined the channels with a little noise reduction and a masked stretch. Asi 1600mm-c @ -30C with Gain 139, Offset 21 300x bias ~60 darks 5h 30min Ha in 300sec subs 3h 10min O3 300sec subs 2h 55min S2 300sec subs. Whit a lot more Ha then O3 and S2 I cheated and ran scnr green, but I'm for now happy with the color balance. I will try to do some more processing when I get time and bring out some more signal, and color, but feel free to let me know what you think about the image at this point.
  12. Observatory from a Shipping Container?

    Hi Alan. I'm not sure how your skill set in working with metal is, but mine is none! To be honest it does depend a lot on size, etc. I f you have good drawings then it almost sounds cheaper to rebuild the structure, than to move a large shipping container if you were to move? I know I have kept my drawings with all measurements, so if I where to move location I could order the timber pre cut at what I would suspect will be a lower price than to hire a crane operator and a truck to relocate a container. It would result in some more work, but I don't relocate so often that it's a big / likely issue. I'm sure it could be done, but not 100% sure how much there is to gain? Good luck on your research / desition, Magnus.

    Thanks for the comments Olly an Paddy, and the likes! I'm happy that you liked it
  14. So this is the Monkey Head nebula in Ha. Imaged with the asi 1600mm-c @-30C 64x 300sec, Gain 139, Offset 21 I'm gathering O3 as we speak, but liked the mono version too. Pretty happy with it at the moment, but feel free to comment with tips or feedback
  15. ASI1600mm cool

    I'm not sure what you can tell from this? but here are Menkib in Ha and S2 (don't have O3). Setup is identical for both, subs are 5min @Unity with offset 21. The stacked images is 4.5 hour Ha and ~1.5 hour S2 Ha S2 The reflection is not showing a lot in Ha ,but in S2 it's very clear! Scope is Equinox 80, with SkyWatcher non reducing Field Flattener and Baader NB filters. Please share what this means.
