Start Date: 1st September 2021
End Date: 30th November 2021

Prize: A personalised mug for 1st, 2nd and 3rd places featuring your image kindly provided by our sponsors FLO :) and a virtual trophy for your signature.

Please post your entries in this thread.  Please include details of your capture since this can be helpful to other members. Emojies are welcome but please don't comment on posted images.

Ok, I'll kick things off with what I'm sure will be the first of many M27 images - this one is for only 40 minutes between clouds, with haze :) 

Details
AA294C ProTec -0C gain 400 (unity gain)
Edge HD8 + Optolong CLS filter | EQ6R-PRO mount | Celestron OAG (ZWO ASI 178mm) | Capture APT + PHD2
4 x 10 minutes lights, 30 darks - no flats / dark flats
Focal length = 2070mm, uncropped.

My latest attempt at IC6960 and associated nebulosity.

Taken over two nights, 1st & 7th September with the following kit:

Evostar 80ED DS Pro on a HEQ5, ASI294MC Pro fitted with L-eXtreme filter.

Subs - 80x120s @ -15°C + 78x180s @ -10°C

30x darks, flats & dark flats. Sacked in DSS & processed in PI.

M27. My first image with a ZWO ASI224MC as an imaging camera. SW 200P on HEQ5, unguided.

200x15', gain 135. picked maybe 140 of them. 190x15' darks, 100 bias. 2021-09-20 I think.

I've been struggling all summer with this Veil Nebula 2 panel mosaic - it's been beset with various problems including failed meridian flips, operator error (failing to turn on camera cooler), and a general dissatisfaction with the stars (star problems are obviously even more of a problem with a mosaic). In the end I've gone with the nebulosity from subs using the NBZ dual narrowband filter  (41 and 35 x 240s) and the stars captured without filter (40 x 2 x 10s).

Anyway, I've done all I'm going to do with it, and am reasonably pleased with the result. As it fits this challenge, I thought I'd enter it!

RASA 11 v2, CEM120 mount, ZWO ASI2400MC pro camera.

Here is my humble entry. The Bubble Nebula framed along with M52. 80 subs of 120sec, LSHO filters with ASI1600 mono. Williams Optics ZenithStar 61 mounted on my GEM45. Guided with 30mm scope and ASI120. Bottle 5 sky - but I had some dew issues. Processing workflow DSS for stacking,Siril for linear stretching, GIMP for the composition and color work. This was my attempt at a modified Hubble SHO palette.

Here is my humble effort of the Veil from last night.  57 x 90 seconds using a 61 EDPH II  294MC Pro and L-Extreme filter ( bortle 8 skies )  stacked in DSS then processed in Siril and Gimp.

A second entry from me - bubble in NB.

115 mins oiii

115 mins sii

75 mins ha


Shot with asi1600, C9.25 and f6.3 reducer on an EQ6R-PRO from my garden in Ipswich.

I tried editing in various ways, but in the end settled on starnet and affinity photo. I wanted to get that 'gap in the clouds' view, and really pull out the Oiii - which was the hardest to get as this was mostly shot during periods when the moon was around. I love the fact that the bubble itself really does seem like it is  'lensing' the cloud behind it.

At the end of the day, it's seeing limited at this sort of focal length, so it is binned a bit.

Very nicely done. It's an object that fascinates me. I keep going back to it myself but with rather less success! :)

Not the best image of M27 but the skies (and wind) haven’t been kind these last few weeks. This image is just 10 x 3 minute subs processed in PS. Captured on a ASI533MCP using a WO GT71 and an L -eNhance.D8E42BFE-D5CD-4582-8DD4-75C507CCD953.jpeg.5999663e66118d9b04c4f9a914ad1234.jpeg

I added this image to the Deep Sky section of the forum a few weeks ago asking for any constructive criticism and a couple forum members mentioned their could be more detail that I could pull out in post processing so today I revisited the data trying to keep as much of the faint Ha around the Veil as possible.

Taken using a Redcat 51 on a HEQ5 and ASI1600MM 

5.5 hrs of Ha

3.5 hrs of OIII

Processed as HOO using PI and PS

Here is most of the Veil Nebula complex, captured with a RASA8/QHY268c/IDAS NBZ dual band filter., 20 x 3 min subs, 1 hr integration.

Calibrated and stacked in APP, RGB channels extracted, G&B combined. Then loaded into Startools 1.8, Red assigned to Ha, GB assigned to OIII. Data was binned 71% then taken through default ST workflow. Output from ST separated with Starnet in PI, then Curves Transformation applied. TIFF file loaded into Affinity Photo for further processing.

Thought I'd add another, its a wide field of the Bubble Nebula (Caldwell 11) but of course their's a ton of other objects in there like the Lobster nebula, M52 open cluster just to the right of the bubble and even Nova V1405.

This is the first image that I've processed using only Pixinsight, I've been dragging my heels when its come to using PI as I'm already comfortable using Photoshop but I think this version is better than an earlier attempt when the bulk of the work was in PS. Its still not great and I have so much to learn with PI but I think I'II stick at it.

It was combined as a HOO but what really made this image shine for me was creating a Luminance mask using the Ha image, Deconvolution and MorphologialTransformation tools also really helped.

There are at least seven of the 62 confirmed SNR's present in this field of the Large Magellenic Cloud. 

DEM L316a, DEM L316b, DEML299, DEML218, N157b, SNR 1987a, N159 & very possibly four others. https://hea-www.harvard.edu/ChandraSNR/snrcat_lmc.html

28 hrs data acquired via Stellarmate under near full moon from my light polluted Bortle 6/7 backyard in Melbourne, Australia.

Tak TOA 130 Refractor with TOA35 0.7 reducer, Tak NJP Mount, QSI 6162 Camera, Chroma 5nm Ha & S2  3nm O3 & RGB filters, Lodestar x2 guide camera.

Calibrated & stacked in APP, post production with Photoshop.

We Southern hemisphere folk are extremely fortunate to be able to image the Tarantula Nebula (NGC 2070) and the associated Nebulae, SNR's, Gas shells, star clusters & bubbles within the LMC. 😀

Lovely image and by an amazing coincidence I was just looking for images of the Large Magellenic Cloud as I am in South Africa over the Xmas period and looking for potential targets with a lightweight rig. This and the Carina Nebula seem to fit the bill for a 135mm or 50mm lens on a tracker or AZ-GTi. Alas I don't think the luggage allowance quite runs to the focal length required for the Tarantula on its own!

This is the only PN that I can post. A bare 90 mins H-alpha on M27. My Fleming's Triangle was started at the back end of August so isn't eligible and I have since moved on to galaxies. Ah well...

1387757940_6x900secfromAA8.thumb.jpg.ed1d88d1019fbc81ed6de5baee86a439.jpg

And there's some shadowing on the right that isn't visible in the original.

Hardly worth posting really.
