Eastern Veil - first light with my new (second-hand) QHY8L - and my first ever colour image. Taken on 21 Sep, 2017 @ 23:15 ~ 24:00 QHY8L camera @ -5 C Quattro 8" with CC Avalon M-Uno mount 10 x 5 minutes, guided & dithered (with PHD2 / Nebulosity) FLATS, BIAS, Bad pixel map, de-Bayer, and a bit of stretching and saturation (also in Nebulosity.) It's somewhat cropped since the CC spacing was a bit wrong. -
From the album: Deep Sky
Taken in September 2015 with a Trius SX-26C and ED 80. I had great difficulty in post processing this image since the nebula always seemed to get engulfed by the sea of relatively bright background stars. In Dec 2015, I had another attempt but this time I processed the star layer separately from the nebula. I then merged the two processed images via PS masks. The main advantage with this technique is that it allows you to more accurately control the star layer so the stars don't so bright or large. I quite like the result. LIGHTS: 20 x 300s; DARKS: 30; BIAS:100; FLATS: 40 all at -20C. -
Finally managed to observe the Veil nebula on last Saturday! I remember spending too many hours searching for it during my observations. The milky way band in the morning came up really nice ,almost a continuous band from scorpious to Cassiopeia (managed to see that too!). Thinking about giving veil a last try, we pointed our skywatcher 8 inch dobsonian scope with 32mm plossl eyepiece and lumicon UHC filter and BAM! It was right there, bright enough to show it for first timers too! Looked like an arc or smoke chain coming out of matchstick. All The reports say that Veil neb

As I'm on holiday with relatively dark skies, I've attempted an O3 / Ha bi-colour image of the veil complex, it'll be apparent from the quality that I'm a beginner, especially at post processing. It was done with a mirrorless cam (Fuji X-T1), so needed exposures of 6mins which the star adventurer (or my polar alignment) wasn't really up for, so had to discard a lot of subs, even the ones used show some trailing (8x6mins O3 and 7x6mins Ha, no calibration). Lens was a Canon 200mm F2.8 at F3.4 Used AA6 to stack and do minimal processing, but really don't quite know what I'm doing, still need

We have been battling a bit over that last few nights trying to gather data on a detail of the Eastern Veil nebula - a section known as the Bat. This is 20 minute Ha and OIII subs - 5 hours of Ha and 3 hours 40 mins of OIII. Esprit 120; QSI 690; Mesu 200 - Astrodon 3nm filters. All comments gratefully received.

I finally managed to get my dual rig working thanks primarily to @Patrick Gilliland. This meant I could try out the Chroma 3nm filter in my Moravian G2-8300 camera attached to my Williams Optics Star 71. Mount is the Mesu 200. The target is the Eastern Veil. This is 19 x 1200s (= 6 hours 20 mins) - processed primarily in PI.

The veil Nebula, one of my favorites! I've previously captures this one, but felt i had a lot to improve. This is another attempt on capturing it and consist of a good mix of data captured over several nights. Finally i feel like i'm starting to get somewhere with this target! It's all captured with the QHY5L-II-M camera, unguided with a 50mm F/1.8 and a 135mm F/3.5 lens. Both are old manual Olympus OM lenses. Exposure: 10x 10 min OIII - 50mm F/1.8 (edit: F/2.8, not 1.8) 15x 10 min Ha - 50mm F/1.8 (edit: F/2.8, not 1.8) 4-part mosaic, total 254x 2 min Ha - 135mm F/3.5 To -
For reasons unknown, we experienced a good night here last night. Indeed, I managed to get 5 hours of data during 'Astro Dark' - all of it with reasonable guiding. I had an hour of Ha from the previous evening. So this made 9 x 20 mins of Ha and 9 x 20 mins of OIII. All captured using the Esprit 120 and the QSI 690. Filters were 3nm Astrodons. I did my pre-processing in PixInsight. The stacks looked reasonable and I just 'kept going' in PixInsight. This is PixInsight with no Photoshop whatsoever, which is a first for me. It is reasonably clean but my original plan was to get at l

It was only nautical dark in the nights here in Norway when i took these, but gave narrowband a try with my QHY5L-II-M anyway, and the results are not bad at all for such a camera i think. It's noisy, but i guess with this little data and a planetary/guide-cam i guess that's to be expected. With more time i think it will give decent results. Taken with the QHY5L-II-M cooled to around -5c and and Olympus OM 50mm F/1.8 lens at F/2.8 OIII 8.5nm: 10x 600s with gain at 20. Ha 7nm: 15x 600s with gain at 12 (i think). No darks, flats or bias.

Only an hour's worth of data, and with a near full moon too. There's still a bit of tilt in the camera to get rid of, and a huge dust bunny (Curse of the Were-Rabbit more like), but it was good to do *any* imaging after the rubbish weather we've had lately. TBH the previous two nights were better but I wasted too much time faffing. Well, here it is: A couple of histogram stretches and a touch of LPF to get rid of the worst of the noise. Need to do a clean-up of my imaging train. Megrez 90, 0.8FR IV, 3nm HII Astrodon, Trius 694, temperature -23 from the readout. Guidin

3 sets of rain showers today after last nights thunderstorm has cleaned the skies, very high transparency. First off I'll list the prize tonight, B352 and B353 near the NAN and seen with no filter- what a stark, black contrast those two "thumbprints" are!! I'm going to list some nebula that typically need filters but under good skies portions of them can be seen: NAN- Gulf section easy, with the rest a bit fainter, Pelican a faint glow Crescent neb- this is surprising really, a sharp, short streak can be seen near the "triangle" locator stars Veil neb- easy, bot

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

This has been a bit of a project. Last year I worked out that my 200mm Canon F2.8 lens and ASI1600 would frame the whole of the Veil complex quite nicely. I captured Ha and OIII data for the east and west nebulae with a Tak FSQ 106 and added this into the widefield image. Although the Tak data had to be shrunk down it did add a bit of extra resolution where it was needed. The difficulty for me has been the processing. I have found it really difficult to tease out the faint wisps of detail and have tried the usual routines of micro contrast adjustments using curves along with Scott R

From the album: Widefield DSO
Same data as the other "mk3" versions, but created in LRGB using a synthetic L channel following a comment from Olly, where L=Ha+SII+OIII with random weighting for each to give something looking ok. Also for a change, I tried mapping R=Ha, G=SII, B=OIII. -

Hello My 80ED telescope was suffering from a lot of bloated stars around the outer 1/3rd of my frames in a DSLR. So I order a new 0.6 flatterner reducer, which arrived yesterday in the post from Orion Optics in the UK. Last night was amazingly clear at my home, at 2am I could make out the milky way. This does not happen often where I live in Sussex. So it was a great night to test out the new kit, considering that it pushed my 80ED up to F4.5.It is just as well as the temperature outside was 18C and my DSLR sensor was running at 28C.This allowed me to image at ISO1250 for 120sec exposures.

I took quite a long time, but I found enough time this weekend to do 2 testshots on NGC 7000 and the Veil Nebula with the following equipment: mount: Astrotrac Camera: modded 450D with Astronomik CLS Clip-Filter - set to ISO 1600 Lens: Nikon Ed 2.8 / 180mm, stopped down to 4.0 - which was a lucky, pretty cheap purchase on ebay Unfortunately the CLS Clip-Filter i have is not the CCD-type with built-in IR-Block, I think, the CCD-type will lead to better results, as the normal CLS is more suitable for an unmodded EOS. As I had some trouble with humidity, I frequently had to use my wifes hairdrye

Main image, light cropping and resized. 50% crop of segment. This is the 2nd attempt I had at this. The previous one was with too short a focal length so I never got much detail. Veil taken with EQ6 guided, Sigma 120-300 f/2.8 OS. Canon 450D modified + Astronomik Ha 12nm filter. 14 subs of 4m each. Canon 600D standard + Astronomik OIII 12nm filter. 15 subs of 4m each. Main processing by PixInsight. Finishing touches in Photoshop Elements. Synthetic green channel via Noel Carboni's tools. I know, I need more subs!

Hi All, Had another great holiday in France. Unfortunately only 2.5 clear nights in the week and I picked the week containing the longest day! However I managed to capture 2 targets I have wanted to try for a while and here they are. I believe I over processed the Veil but I got excited as I found myself finally understanding some of the actions in photoshop! I am aware there is a lot of "Red" too - something I am working on correcting as I get used to the camera after being modified. Both were using ED80 on HEQ5 with modified Canon 1100D (with Astronomik CLS filter), guided with ASI120MM on -
First proper go at the Veil Nebula last night. I've selected the best data with 19 lights of 240s at ISO 1600 plus 35 darks and EXIF T of -15C. Stacked in DSS which chose 15 lights to stack. No flats or bias frames as yet. Processed in PS, scaled to 1024px wide and saved as PNG. I also have 22 lights of 120s which I shall try adding later.
