It doesn't look too bad. I would do this one in narrowband, though and add rgb for the stars. The stars are too bright for the nebula to do it in rgb in my oppinion. Adding 5-7 hours of rgb might look nice though.

Thank you!

The mugs are going to look almost too good to use !

I agree!

I submitted mine as well, hope it helps.

Excellent image! I love the colors.

So what to do

You definitely need evidence, so reference and link articles and statistics in your response.

I think you should talk about these 5 different arguments, many of which you had in your original letter but maybe could be expanded upon:

1. Evironmental- both the energy required and fossil fuels and also the effect on ecosystems, birds, ect.

2. Economic- the hundreds of thousands of $ being spent on these lights could be used by actually putting up security cameras or something which directly reduces crime.

3. Human health and mental health- cite articles that have researched the effects both on the mind and body.

4. Impact on science- us astronomers are actually a large impact, we conduct research such as exoplanet photometry, spectroscopy, and other things. This light pollution directly impacts astronomical research.

5. The real impact on safety- that 97% positive response is from a population largely ignorant about the real safety imact. As some of us have mentioned, it is actually the other way around, burglars will not rob a house if they can't see, thus the decrease of crime when it is dark. In fact, I would be willing to bet that the 3% negative response is from the people who actually did research.

I hope this helps.

Thanks, Gorann 

Thanks for the kind comments everyone!

Nice picture HunterHarling, it took me ages to find that Spiral Galaxy in your pic.

Interesting...

I've been wanting to capture this one for a long time... and I finally did these past few weeks. Unfortunately the stars are a bit blown out and have strange diffraction patterns due to the ZWO microlens. Tips/ comments on how to help these would be appreciated  

One interesting thing I noticed was a small galaxy to the right of Electra. Does anyone know what its brightness is?

LRGB: each 50x180s

Total exposure: ~10 hours

FSQ106

Thanks for looking & clear skies.

Really great images so far. My favorite is the Orion nebula, can't wait to see it in color. Good luck with the scope.

Does anyone know when the winners of challenge 26 will be announced?

I’ve been tied up doing star party stuff so not had time to look at this - you’re the first person to have mentioned it as well so I’m not sure how worthwhile the challenges are anymore - the effort to organise them doesn’t seem worth the amount of participation they’ve generated recently 😞

 

I very much enjoy them... and I know others do as well. Maybe we just need some new ideas for the challenges. 

This is a great idea. I'll have to do some star trail shots.

@Grant, do you know when the October challenge will be announced?

The Atik 460 tends to have noise in the form of overly dark pixels in the background sky and its star colour is - how can I say - not reliable or convincing and needs working on. It is also hard to stretch up the background sky without blowing out the rest. I end up settling for a darker sky than I prefer. The Moravian 8300 produces a colour balance at parity of exposure which needs considerable adjustment in post processing and the colour data seems curiously weak. I haven't been using it for all that long so it may be my fault, but I've done darks and flats absolutely by the book several times. It's also possible that the filters are not as they should be but they are in a size of which I have no others to swap round.

That's interesting because I feel like I've had the star color issue with my ASI1600. But I guess it could be my filters.

Both of the other cameras I use throw up things which make processing harder.

Olly-

Do you have some examples of these? Just curious.

Very beautiful indeed, your guiding must be awesome cause your stars are pinpricks.

Thanks  My guiding is good so the stars are round at least, but they are just a bit larger than usual.

This is 22.2 hours of Ha exposure of the Bubble nebula, NGC 7635. Unfortunate I seem to have an issue with my filter offsets and all the data turned out slightly out of focus  It is interesting to see the structures that were accentuated by removing the stars, particularly the nebulae to the upper right of the bubble.

Very nice, amazing star color also

Excellent, Göran. 

What? You can't do the processing in your sleep? 😉

You can stack in you're sleep

Very nice picture btw.

Surprisingly difficult target considering its angular size and you have done really well.  Really well.  One of the best M33 I've seen, in fact.

Wow. Removing the star gives it such a different feel.

Yes, it really does.

Magnificent. It's worth zooming in on the central bit.  It looks like both cloud and rolling surf. 

The center is really interesting...

Here is about 44 hours of data on the Wizard nebula. A LOT of processing went into this image. It was difficult to get the traditional orange/ blue palette since the S and O data was so dim compared to the Ha. I finally settled on the starless image, as it brought out the dimmer nebulae in the background.
