Hey, I found Spock's lost brain! Site: Backyard, rural Poland, Bortle 4. Aquisition: Three warm June nights. Seeing was quite terrible during two of those, when I was after OIII data. Ha- 33 x 300s OIII- 74 x 300s Gear: Telescope: SkyWatcher Maksutov-Newtonian MN190, 190/1000 mm Camera: ASI1600MMP, Filters: Baader Ha 7nm, Antlia OIII 3nm, Mount: SkyWatcher EQ6PRO Guider: SvBony 240mm, ASI120MM mini, Other gubbins: ZWO EFW, ZWO EAF, ASIAir V1 Processing This one was a challenge for two reasons: - showing Ha details while giving the oxygen bubble its proper place; - trying not to flatten the brightest parts of the nebula too much and preserve details there; Processed Ha and Oiii in Pixinsight but I've moved the stretched images to Photoshop. I just couldn't get acceptable colors in pixelmath. Also, any attempt at creating luminance seemed to make the picture worse. Thus, I've tried something new. I've coaxed as much detail as I dared in Ha and Oiii, stretched them with the GeneralizedHyperbolicStretch script and moved on to PS. There, I used the color gradient tool to assign them colors and combined them. Some tweaking with selective colors and levels and here it is. I'll never be happy with it, though. There's no single best way to show this messy and convoluted nebula :-)

So it took me a little bit of time to get everything setup, accessories plugged in and the mount polar aligned (turns out the Skyguider Pro polar scope is not particularly spectacle wearing friendly in terms of eye relief) but I got there. I then point it up at Cygnus to see what I could capture. I was using the Samyang 85mm f1.4 AS IF on my Canon 600D. I forgot to focus my first shot, but I think my focus was okay after that. Some of my frames were good, some did have a small amount of trailing. I did 30 x 60s of Cygnus (at least I think it was, I think I can see some nebula of some description in the top right) at f4 and then I tried 30 x 60s of M31 Andromeda at f5.6 as well. I've also never done any image processing before so downloaded GIMP and did some basic curves and levels with that, and a star map on Cygnus, but that's about it. I stacked them both with 20 dark frames and 20 bias frames in DSS. Attached are both images. Andromeda was quite low and over light pollution so there's quite a pronounced glow that made image processing tricky. Overall I'm happy woth my first attempts, but I realise I could improve tracking, take longer and defintely more frames next time and also probably not be lazy and do more darks and some flats next time around.

I've been less active lately in this hobby, but I've a few images done, others waiting in the pipeline to be processed. This is a "crowded" area of our Milky Way galaxy, visible all summer from the northern hemisphere. The Cygnus constellation is home of many named and nameless nebulae. Starting from the left (North), below the brightest star, Deneb, the Pelican and the North America Nebulae are very popular; going to right, just below the brightest star close to the center of the image, Sadr, lies the Gamma Cygni Nebula. A bit towards the top-right there's the Crescent Nebula and going forward top-right, there's the Tulip Nebula. Finally, at the bottom-right corner, the Veil Nebula, a super nova remnant. All these are surrounded by shiny gaseous filaments or dusty patches blocking the light. I started this during the pandemic lockdown. All of the data was captured from my hometown from a balcony brightly lit by a sodium street lamp, but the narrowband filters did their job well, blocking successfully the sodium emission. A total of 23 hours is made of 2x3 panels composed in a larger mosaic, each panel consisting in about 1h of exposure for the red Hydrogen and 3h of exposure for the cyan Oxigen, all through a Sigma 105 macro stopped at F/4, ASI1600MMC with 6nm Astronomik filters. I'm planning to shoot RGB data too and make an RGB/HOO composition.

The ongoing deluge continues in my neck of the woods so, instead of enjoying the lack of a moon, I’ve scanned my first sketch, made this past October: Open Cluster IC 4996, in Cygnus. I’ve got a long way to go, especially with getting the scale right, but I definitely enjoy the almost Zen like state of focus that I fall into while spending 30+ minutes on one DSO. It’s also made me spend more time on each object while not sketching; its incredible the details that pop out after 15+ minutes, even in light polluted skies.

At the end of December 2016 i captured a bit of Ha data on this target with the Polemaster and a 135mm Olympus F/3.5 lens. The image turned out quite well despite the low resolution, but i always felt something was missing - the colors... My 550D on the Explorer 200 don't get nearly wide enough FOV to match, so finally i decoded to finally give it a go with my first attempt on a mosaic. With the moon at 95% and the huge resolution difference (0.86" RGB and 5.76" Ha) i wasn't sure if i were just wasting my time, but it turned out better then expected. The RGB data is a 4 pane mosaic with a total of 46x 120 sec exposures at ISO 800. Stacked in DSS, combined with MS ICE, and processed in PS. Ha data is 35x 120 sec.

Pickering’s Triangle (Seimis 3-188) It is a little early in the season to be imaging this object as it didn’t appear above my local horizon until 00:50 when I started the project earlier this month but with nights getting shorter as we approach the summer solstice, it made sense to make an early start even though it took several nights to capture the data while ducking and diving between the clouds and early morning mist! Discovery Pickering’s Triangle is part of the supernova remnant known as The Veil Nebula in Cygnus. The Veil Nebula itself was discovered by William Herschel in September, 1784 but this faint region was only later discovered photographically in 1904 by Williamina Fleming at the Harvard Observatory. The discovery was made post publication of the New General Catalogue (NGC) so it isn’t included in the catalogue. Although it wouldn’t happen today (I hope!), the custom of the time was to credit the discovery to the lead astronomer, in this case Edward Charles Pickering, the director of the observatory. Image Stats Mount: Mesu 200 Telescope: Sky-Watcher Esprit 150 Flattener: Sky-Watcher Esprit specific Camera: QSI 683 WSG-8 Filter: Astrodon 3nm Ha and 3nm OIII Subframes: 6 x 1800 sec Ha, 13 x 1800 sec OIII Integration: 9.5 hours Control: CCD Commander Capture: MaxIm DL Calibration, Stacking and Deconvolution: PixInsight Post-Processing: PhotoShop PS3 Description The nebula can be found in the north-west quadrant of the Veil Nebula near NGC 6974 and 79 (see whole Veil Nebula image below). Lying around 1,400 light years away, the beautiful filamentary elements are the expanding shock-wave from the progenitor star that went supernova here somewhere between 5,000 and 10,000 years ago. Position within the Veil Nebula Visually, the nebula responds well to the use of an OIII filter as the region is rich in OIII emissions as can be seen in the blue/green filaments in the above images. Photographically this is a wonderful object that responds well to both LRGB and narrowband imaging and the example shown here was captured using Ha and OIII filters. Although there are sulphur emissions (SII) in this region, this object responds well to my favourite imaging method of 'bi-colour’. This process uses just Ha and OIII filtration wherein the OIII data is mapped to both the ‘Green’ and ‘Blue’ channels and the Ha is mapped to the ‘Red’ channel. The greyscale images below show the individual Ha (left) and OIII (right) images used to produce this image. As you can see from the 'Stats' above, I have a whole load more Ha to collect to complete the image! The individual Ha and OIII images
