Well, since I already captured this object as part of December’s challenge and since it’s in a far from ideal position for imaging for me right now, I’ll just resubmit that image, slightly modified.  It was taken “this season”, so it’s legit.  The Astrobin link from the small image does seem to work, although it shows just an hourglass right now.

Here is a widefield image of the 3 major Auriga DSO captured this season (22 Dec 2019). The 3 DSOs, of course, are ; IC 405 at the top, the IC 410 in the middle and IC 417 below that: 

 

12-22 Auriga-200mm csc 206Min STCrCNJ1.jpg

 

It was captured this image from my suburban Houston (Texas) backyard using the following gear :

 

Imaging telescope/lens: Older vintage 200mm f4 AIS AutoNikkor lens at f5.6,

Imaging camera : HA modded Nikon D5300 at ISO 800. Total integration time was 206 minutes (33x2Min + 35x4minutes),

Mount : iOptorn's iEQ30 Pro,

Filter : Dual narrowband filter from Omega Optical - the Improved NPB filter with bandpasses near HA and OIII emission lines,

No guiding or dithering,

Registering and Integration done in APP (Astro Pixel Processor) and post processing done in StarTools with final touch-ups in FastStone image viewer. 

 

At the image scale I am using, the tiny Tadpoles are barely visible. Oh well! At least the rest of nebulosity came out reasonably well.

 

Cheers & Clear skies ...... Anil

I had not captured IC410 previously so +1 on target selection.  On the other hand, my integration time is relatively limited and the results would benefit from additional imaging time.  Two mostly clear nights so far and a lot of clouds in the forecast so I decided to go with what I have. The other limiting factor is that I can image approximately 2 hours after the meridian before I'm taking pictures through trees, and this window is getting narrower as IC410 is past the meridian at dusk.  I wasn't really looking forward to this challenge initially due to the limited time I would have, but it gave me a chance to improve my results with IC405 which I had previously imaged.  Squeezing in both IC405 and IC410 barely fits within the frame of my widest FOV configuration, but IC410 by itself is a little small in this scope.  Overall I ended up liking this challenge much better than I originally thought.

This picture uses the ASI071MC-Pro camera,  at 200  gain targeting -5C,  the STC duo band filter,  a  ES AR127 achromat at  f/5.2, and a CEM-60 mount.  33x4' taken on  3/14/20, stacked  in DSS, and developed in Star Tools and Gimp.  The Dark calibrations were not working properly,   and were leaving strong color gradients, so this picture is calibrated with just flats and dark flats.

 

The AR127 is a wonderful visual telescope, and corrects well in the color range of the STC filter, but is a challenge to use for photography, as the  focuser is not meant for heavier loads.

Amazing images from you all!  It is cool to see all the different interpretations and capture methods, and nice to have something fun to think about instead of worrying about the virus.

 

I was hoping to encourage you all to please post some details about how you processed.  Especially with the narrowband images: are they SHO, HSO, HOO, or whatever other types their may be.

 

I ask this because, as a long time beginner (lol.gif), it helps me to visualize how much signal to expect from the filter types.  Last night I picked up about 3 hours of data.  The H alpha exposures turned out great, but the S2 and O3 are WEAK...  Not sure if I should try for longer exposures with those filters, or if I should switch over to RGB for an HaRGB combination.  Any suggestions?

 

In general, is there much O3 and S2 in IC410?

 

Oh, and whoever picked this object for this months challenge, thumbs UP!

 

Thanks,

 

Scott

Tom,

 

Thanks for sharing that, and your picture is awesome!  The colors are very pleasing!!!

 

So based on that info, there should be a fair amount of O3 signal, but very little S2?  Hmmm, maybe I'll shoot a bunch of O3 with longer exposures to see what I get.

 

I wonder how an HOO would turn out?  And is there such a thing as OOH?  Probably would be ugly star colors, but the blend would be nice with lots of blue.

 

Again, thanks and great shot.  You better start working on picking next months target in case you win the challenge!  Although they are all really great.

 

Scott

Scott,

 

I didn't do an HOO, I used all three NB images to create one image. I had one that was to blue, and then this one, which pleased me more.

Hi All,
Here is my attempt at IC410 in SHO.
The target was not in an optimal window for data collection very long each night, so I tried to get going as fast as possible each night that was clear, and there were clouds to deal with as well. I was glad I did not have to use time getting aligned as SkyX ProTrack worked very well and all I needed to do each night was grab a guide star. My guiding was 0.6 to 0.9 arcsex/pixel each night which I was grateful for given that I was collecting 900sec subs with a SVX152T at f8. FWMH averaged 2.38

56 subs @ 900sec each (14 hours total)
Feb 25: Ha=7  Oiii=6  Sii=6
Feb 26: Ha=6  Oiii=6  Sii=6
Mar 02: Ha=5  Oiii=5  Sii=4
Mar 17: Ha=2  Oiii=2  Sii=1
Flats: 20 each, Bias: 15, Darks: 15
Processed in PI. Created a synth L image for the detail to go with chrominance image then blended them together. Many thanks to Ron Brecher (AstroDoc) for his expertise with linear & non-linear post-processing.

What a cool object that I'd never tried before.  And probably wouldn't have tried if not for all the exceptional and inspiring images posted by you all!

 

So I gave it a shot under my Orange/Red skies in typically cloudy rainy Oregon.

  • Shot from 3/17-3/20, my first multi-night attempt.  And well worth the effort.  Normally my data (not enough data) blows up when I stretch things.  This was much cleaner and was pretty easy to process.
  • Orion Atlas mount controlled via ASCOM
  • Celestron 9.25SCT with 0.63 reducer
  • 50mm guide scope and QHY290m guide camera (having failed using an OAG...)
  • ASI1600m and ZWO filters, gain 300 offset 50
  • Captured using SGP and tracking with PHD2
  • 45 Ha exposures at 1 minute each.
  • 95 O3 exposures at 2 minutes each.
  • S2 exposures at 2 minutes gave me very little signal so I processed as bicolor
  • HOO processing using Nebulosity4 (as I haven't made much progress with PixInsight…)
  • I also tried and OOH pallate and that was a train wreck!  Weird colors for sure...

Thanks to Goofy for inspiring us all, you are greatly missed!

{sigh}

 

I gotta get me a new camera...  A request to whoever wins this month, pick something not emission-based.  Please?

 

The following is 3.5 hours worth of integration, taken over the course of 3 nights earlier this month (3/4, 3/11, 3/12).  Tonight 3/26 is marginal (transparency not all that good), and the rest of the month is worse, so this will be it.

 

I've concluded that my NON-modified Nikon D3200 is just not sensitive to Ha light.  This is one of several targets that I've failed to capture much of anything in that part of the spectrum, and the lack of good sky transparency when it wasn't otherwise raining surely hasn't helped.  As you can see, what nebulosity exists isn't in the Ha portion, and the tadpoles are hiding.  Oh, well.

 

Camera:  Nikon D3200, unmodified.  Shutter controlled by Intervalometer

351 subs, a mix of 30 sec & 60 sec at various ISOs between 3200 and 12,800, trying to extract a bit more of the nebula

Total integration time = 3.5 hours. 

 

Telescope:  Stellarvue SVA130EDT (130mm f/7)  No flattener or reducer

Mount:  Celestron AVX

Guider:  ZWO 60mm f/4.6, with ASI174 guide camera

At-mount computer:  4 GB Raspberry Pi 4B, Astroberry 2.0;   CCDciel, ASTAP, PHD2.

Stacked with a mix of Deep Sky Stacker and Sequator

Processed with StarTools 1.3.  Slightly cropped due to imperfect Flats

 

The integration process stacked the first 2 nights with their respective calibration frames, then the 3rd night separately, then combined the two stacks together.  Trying to stack all 3 nights at once yielded a bizarre image a few dozen pixels wide and full image tall.  No clue what happened, not going to mess with it.

 

Don't laugh...
