Hello all,

 

digging in my old data I found that I have two objects I made three attempts on until I was happy with the result. So I thought why not open a "Post your ...." thread.

 

rules:

- 3 at least

- each attempt new data, not just reprocessing

- if you have a story to the images, feel free to tell

- not a competition, just for fun

 

 

Here is my 1st object, C19, the cocoon nebula

 

2017, number of subs no longer available, GSO RC6 on AVX, unmodded Canon T3i:

C19_2017_low.jpg

 

2018, 54x3min OSC, unmodded T3i , 49x2min clear L, T3i mono mod, 28x15min Ha T3i mono mod, GSO RC8 on AVX and EQ6-R:

C19_2018_extralow.jpg

 

2021, 101x5min OSC, unmodded T7i, 49x15min Ha, T3i mono mod, GSO RC8 on EQ6-R:

C19_2021_extralow.jpg

 

... hang on ...

I haven't been doing this long enough to have a series of three of the same image, but I do have a progression for the same region of the sky with different technique and processing...

 

Here's an early attempt at a widefield of Orion in late 2019... subs were taken with a Skyguider Pro, Ha-mod Canon 600D, and a combination of Rokinon 135mm f/2 and  AT60ED. I was pretty happy with it at the time. 2-panel mosaic of 748 subs of 60-seconds.

Annotation 2021-09-20 123201.jpg

 

Then in March 2020 I wanted to get an even wider field of view, and re-shot with a nifty fifty, same Skyguider, and same camera. 9-panel mosaic, 208 180-second subs.

Annotation 2021-09-20 124252.jpg

 

Third submission would be from February-March 2021, with a 26-panel mosaic of the same region. Same camera, Rokinon 135mm f/2 lens, and iExos-100 mount. The iExos really helped in framing each panel, but it still wasn't lined up perfectly and I had to take a healthy crop of the final mosaic. 1326 subs of 120 seconds.

Nice to see Takumar 200 images. I only took a few and moved on to the Askar 180. Also nice to see you taking even 4 attempts. The last one is just fantastic for Bortle 8!

Thank you! Yes, the Takumar was amazing. I am actually now thinking of purchasing either of the two Askar lenses. 180 or 230.

Your latest Cocoon is just incredible. I don't think I'll ever be able to reach that quality from where I live now.

My Veil Nebula attempts over the years.

 

 

 

VeilNebula-10-04-2010aP3C1SSS.jpg

Date:10/4/2010
Camera: Canon EOS-20D
Lens: Tamron 28-300 set to about 200mm and f/5.6
Exposure: 121x2min at ISO 3200

 

 

 

VeilNebulaPartNGC6992-2013-09-02P2SSS.jpg

Date:09/02/2013
Camera:Canon Rebel T4i modified
Telescope: 110mm f/7 ED refractor (Orion)
Exposure: 39x3min (1hr 56min total) at ISO 1600

 

 

 

NGC6992-2020-08-17-P2C1SSS.jpg

Date: 8/17/2020
Camera: Canon Rebel T4i
Telescope: 92mm f/5.5 triplet (Astrotech AT92) with focal reducer
Exposure: 58x5min (4hr 50min total) at ISO 800
Acquired using BackyardEOS, stacked using DeepSkyStacker and processed using PixInsight

 

 

There were equipment upgrades between each.  Ironically a huge factor was an anti-dew system allowing to collect enough data on a clear night.

The Fuji negative is amazing! Sometimes people talk like astrophotography only is possible with digital cameras. Your image clearly shows that great astro photos have been possible with film as well. Thank you for posting.

The film one all had relatively short exposure times in today’s standard. I kind of wonder what will happen if I take many subs with film to accumulate >5 hr of exposure and stack them. Will the results be super cool? I did that on M31, but not M42. Later I will find out the M31 ones and share them here.

I agree, the Fuji 400 shot is just stunning.  When I first scrolled down to it, I just stopped right there.  How could anybody really do better than that?!  It doesn't have the subtle dust areas that the last couple of images have, but look at those colors.

 

I tried some film AP many, many years ago (Tri-X, if you remember that), and I did get a couple of images.  In some ways, film was harder.  You could work for 20-30 minutes on one shot and something would be wrong and it was a total waste.  And you would see reciprocity failure unless you cooled your camera/film to -2000℃.  (I'm exaggerating, of course.)  But in some ways it was easier, because you could get a really nice image in.... 20-30 minutes.  If you knew what you were doing, of course, which whwang clearly does.

Can you give us some detail on this one? Probably multiple different exposure times involved? I'd like to get something similar this winter. I think I'm not lacking the ability to capture the data but I'm troubled processing them to such a piece of art.

Hi Elf, thank you so much for those kind words.

 

This was my first light with the ASI 2600mc and because of that it ended up as only 90 minutes total integration and you are right 3 different exposure times; 15 X 180s, 15 x 120s and 15 x 60s. It was taken with the L-enhance but this was not processed as HOO - just as it came out of my stacker (it was APP at the time and I did not use any of the HOO algorithms). each of the 3 exposures was calibrated and integrated on its own then I followed the Light vortex tutorial on HDR https://www.lightvor...-hdr-image.html

 

This involved doing DBE on each image then combining the three using HDRComposition.

 

After that it was BN, EZdenoise, HT to nonlinear then HDRMT following the next step on the light vortex tutorial. After that it was pretty much normal processing with SCNR, CT for brightness and saturation, MLT for sharpening and a little TGVD on the dust.

 

I do hope this helps and I look forward to seeing your result later this year.

So, I hope it's ok to post progression pics where the main camera was not necessarily a dslr?  Let me know if it's not ok, and I'll remove it.

 

Sometimes a progression can be a little sideways.  One of my earlier M42 area attempts that I was reasonably happy with at the time was this one, taken in 2007, under bortle 5 skies:

https://photos.app.g...EHzvg9c9B7avAh6

 

What still surprises me today is how sensitive that camera was in Ha, even unmodded.  No unmodded camera I've owned since has shown that sensitivity.

 

The next attempt was more to show I could still do it.  I had moved into an area with Bortle 9 skies, but that didn't deter me.  So I got this one:

https://photos.app.g...FHJ5sBMiRydCVH7

 

Fast forward to last year.  I had moved to a bortle 4 location, used a faster lens, and spent way more time on the subject (mosaic) than I had planned.  The result is semi finished, but shows the potential of fast lenses under darker skies:

https://photos.app.g...XtHzFcmZaYFRmJ6

 

Honestly, I don't know if I'll ever try that again.  I may do a milky way one from my current dark sky location.  It was a pretty exhaustive experience, not shooting, but post processing.  My pc was absolutely smoking at the end of it.

 

Btw, my post processing skills have improved a little since the first one, but honestly, I can't say they improved all that much.  I give most of the credit to: skies, scope/lens, and camera, in order of importance.

 

Hope this helps.

Hey, this is just for fun. Don't take the rules too serious. It's only that I'm tired of discussing 7 versions of the same image that only have a different level of saturation or brightness. Great images.

 

This became a great thread. I'm most impressed by the analogue examples like the Fuji film and the Tri-X. 1969. One year later I was born. In my eyes that image is an historic document. Dave, thank you for sharing. I'm deeply impressed what was possible at the time.
