Total 18 hours (6 Ea x SHO- 3nm) - using ASI 2600MM & FSQ130ED on Trident P75 mount.

- Thanks Martin...appreciate the comment. 👍

NGC 2170 is a reflection nebula in the constellation Monoceros. It was discovered on October 16, 1784 by William Herschel. NGC 2170, is also known as the Angel Nebula and lies to the right side of the image. NGC 2170 is a dusty reflection nebula and stellar nursery that formed about 6 to 10 million years ago, located at the edge of the elliptically shaped, giant star-forming molecular cloud Monoceros R2 (Mon R2), some 2,700 light-years away in the constellation of Monoceros.

Thank you for that. I have actually updated the image again (on my website) - I reduced the green ever so slightly....I like it better now and won't tamper with it again. (Also on AstroBin where there is quite a high resolution copy: https://www.astrobin.com/xwfi7y/E/ )

Thanks very much Martin. I see you are mostly NB imaging (like myself), so this would be "right up your street" 😉

First image of the year and hopefully a return to posting here on SGL. I increased the colour saturation since I first finished this image a few days ago.....so you either like it or hate it for that reason. But whichever, this target does not get too much attention....so hopefully some can appreciate it for that reason. For those interested there is another version on my website - which is a mix of HSHO (as here) and Foraxx Palette.

Lovely result 👍

Not very popular but it is available for quite a long period - Oct, Nov, Dec being best time. However...it is not so easy to image - it has a very weak signal.

Thanks. The "close-up" image of the pillars is actually a mix of HSHO & Foraxx.

Thank You 👍

I actually experimented some with Foraxx palette and found that I did not particularly like it in my images. However, it was interesting to see the final colours but in the end, I thought it yielded more pleasing results when mixed with SHO palette.

NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800–1000 pc distant with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun. The star is one of the primary sources illuminating the nebula and shaping the complex's famed pillars of creation-type formations, Imaging telescopes: Takahashi FSQ130ED Imaging cameras: ASI 2600mm Mounts: JTW Trident P75 Guiding telescopes or lenses: Takahashi FS60CB Guiding cameras: QHY CCD QHY 5 II Focal Extender / Reducer: None Software: Sequence Generator Pro SGP (for capture) PHD 2 (guiding), Astro Pixel Processor & PixInsight, Filters: Astrodon Ha, SII, OIII, Accessories: Robofocus Focuser controlled by Lunatico Armadillo, ATIK EFW3, RB Focus Gaius, RB Focus Excalibur.

This is one that was on my "To Do" list for some time. When I finally did get to do it....it was tougher than I expected....but happy now with this final rendition.

That is a hypothetical question. On the face of it the answer is yes - because there would be less processing of the data. In the real world though....you can only tell by making an image with the data.....and your results may or may not bring that potential to the fore. (This is simply because there are so many variables at play when processing the data....for example....process the same data on two consecutive weeks and you will have two different images from the same data).

Hi Rodd......I just looked at my web page (https://www.kinchastro.com/rosette-nebula.html) and I have 8 different Rosette images, processed at various times (2020 - 2022) with the same data. It was fun doing things slightly differently each time but none of them are the "final image". Perhaps in a year's time I will go back and play with the data again. Bottom line - we never achieve that perfect image. We amuse ourselves when we have the time, trying to make that final image that we will never want to change. It rarely comes! In this instance, you must ask yourself if the time needed to gather more data with the TOA will give you that final image (never to be touched again)......OR....would your time be better spent picking a new target and starting afresh with TOA or FSQ - as pleases you. Nobody, but yourself can answer the question that you have thrown open to the floor here. In the end, only you will truly see the minute differences between one "final image" and the next "final image" and it follows then, that only you will decide what is..... THE final ... that needs no more data...no more processing!

Thanks for the info. I am considering changing out the dome I am presently using.....just looking for ideas!

Just wondering.....what dome is that in your images?

I think it is low for me - and I live in SE Spain (Lat. 37½°N). I actually started another image in this area just a couple of weeks ago but gave up on it - 1st weather delays then equipment problems. Now I plan a weeks away from home. So it will be something other than this when I get back to imaging again.

Thanks very much 🙂

Thanks Alan.....as for the bug.....I reckon there are always bugs in NB images 🤣

Thanks very much Jim - appreciate that.

Never throw out old data. No harm, once again, playing with old data. The 3 master subs I used today are from *6 Years Ago* but I enjoyed spending some time reprocessing that data - no apologies for the over-processing ..... I was just having some fun. Data from July 2017 with FSQ106ED and QSI 6120 camera.

Thank you very much Adrian. Not sure why I have not posted in such a long time... must write a note to self to resume posting. 🙂 (Although, in truth, I have never gone away as I still receive most posts in via email).
