Widefield Cygnus

[swag72]

This was taken last night with my 7D (unmodded) and an Astronomik clip in LP filter fitted. It was taken with my 24-70L lens at f/4 and 32mm.

This is a total of 41 x 180 sec subs. No flats or darks as for some reason DSS wouldn't accept my flats. Processed in PI.

Would really welcome feedback and comments on this - It was devilishly difficult to process as well.

**Edit image added later in thread - More contrast suggested **

That's stunning! So many stars!

Why the 7D and not the 1000D?

The modded 1000D with the filter removed will not achieve focus with my usual lens's - Unfortunately. So I had to try another way!

[Digz]

Wow, that looks superb. I like it a lot!

[ashworthacca]

Sara, that looks superb. Very nicely processed ...it is difficult with all those different areas to bring detail out. Keep em coming Sara.

[Psychobilly]

Nicely Done

Hope you get an answer for the modded 1000D

Peter...

[swag72]

Got an answer for the modded 1000D Peter - It's had the filter removed, so will not focus with the normal lens

So it looks like the 7D now for widefield!

Thanks for the comments Digz, Martin and Peter - glad you like it

I'm sure I heard from other people on here that only AF was affected by the filter removal and you could still focus manually with lenses attached

I think Merlin66 could help answer for sure as I know he asked about it a while back

Merlin and I have had a chat already about this! I will definately go back with the 1000D tonight and have another go. I manged to get my focusing sorted out with the 7D, so armed with that experience, I'll give it another go!!

[jnc71106]

Oh great will keep an eye out for the pic as it's already a fantastic shot with the modded camera it could only get better

Hi Sara - It's a shame that there's not more going on in this region isn't it...?!

Just for a laugh I thought I'd run it through Astronomy.net - Your field contains:

• Part of the constellation Cygnus (Cyg)
  
• IC 1311
  
• IC 1318 / gamma Cyg nebula
  
• NGC 6940
  
• NGC 6960 / Filamentary nebula / Lace-work nebula / Veil nebula
  
• IC 5068
  
• IC 5070 / Pelican nebula
  
• NGC 6992 / Network nebula / Veil nebula
  
• NGC 7000 / North America nebula
  
• NGC 7092 / M 39
  
• IC 1396
  
• The star Deneb (αCyg)
  
• The star Sadr (γCyg)
  
• The star Gienah (εCyg)
  
• The star Alderamin (αCep)
  
• The star δCyg
  
• The star ζCyg
  
• The star ηCep
  
• The star κCyg
  
• The star ι2Cyg
  
• The star 31Cyg
  

I did a very quick comparison of a similar widefield I took a few weeks back and I actually prefer this image with an unmodded camera - If it were me, I don't think I'd be too unhappy about not being able to take widefield with the modded 1000D... and you've certainly pegged the focusing!

[Merlin66]

Don't forget the umteen Wolf Rayet emission stars also recorded!!

Think of the amount of spectra you would have collected on one night with a grating in front of your lens!!

[AndyUK]

Hmmm.... Talking of which, it seems to have missed out NGC 6888...(?).

Sara - If you can get your 1000D focused on this it might be interesting to image this again and then compare the two side-by-side...? (and also see if astronomy.net picks up more next time!). Still, I suppose it's nice that Astronomy.net is reporting what it sees and not what it thinks it should be able to see...

[swag72]

Just had a dinner invite this evening, so tonight will be out! Will definately try again soon. Thanks for your comments Andy. Will be interesting to see the difference if I can get focus.

[AndyUK]

Just had a dinner invite this evening, so tonight will be out!

Isn't that SO inconsiderate of friends?! I have the same problem - One of my "drinking buddies" has an uncanny knack of inviting me out just as I'm putting the OTA on the mount... (I don't usually like to say no, but I did blow him out last Sunday!)

[swag72]

Following on from a couple of comments, it was suggested that I needed more contrast on this shot. So back to PI and more contrast added - Do you think this is better now?

It's difficult to decide to be honest what is best!

[AndyUK]

Probably a personal thing, but I think I prefer the new version...

[Psychobilly]

Somewhere between the two would do it for me...

[swag72]

Thanks Andy and Peter - I am out again, and did manage to get focus with the 1000D, it was just me being a twit! So, I am wondering about doing a mosaic now!!

[AndyUK]

(Good news about the 1000D... )

[Coco]

Superb, what I like about these is that they give the imager or observer a real scale reference, carry on

[MartinB]

Lovely shot and I like the high contrast version.

[swag72]

Cheers Guy and Martin. I've worked on another process variant, which I do prefer, but don't want to burden you all with more!! Will wait until the mosaic gets done - If ever!!

Burden away... we dont care

[RobH]

Very nice.....high contrast version for me too.
