The supernova remnant Sh2-224 in Auriga really is a challenging target. It is soooo dim! I spent about 14 hours imaging time for this HOO-RGB:

57 x 300s OIII

25 x 30s R/G/B for the stars

I recently imaged this object along with Sh2-223. Yours is much better!!! Great work indeed! I did it in HaRGB and now wish I’d gotten some OIII data.

Pete, that is absolutely fantastic.  You really pulled all the detail out of that one.  Great work.

That’s a great image. Lovely colours that are vibrant but not cartoonish.

Cheers,
Ian

It's like a neon light in parts!  I love it!  You did an amazing job!

Hi Anil, Miguel, Bloated Star, Kevin, Ian and Sean, glad you like it! I really did not expect get such a result shooting from my balcony in the village. This motivates me to go and look for an even darker target....wink.gif

That's brilliant Pete, wonderful result with your APO. Also from your balcony makes this result even better :waytogo:

Thanks al lot Mert! It's not so dark on my balcony , I have a streetlight 20 m away in SW direction on the same hight level and every few years they build a new girdle of houses around our little town from E to SW so I am quite surrounded from lights sources meanwhile. But the Scope is fixed in place on a pier in a shed and always ready to shoot. This helps bringing enough photons onto the sensor.

 

Cheers

Pete

Hi Pete,

You are really on fire! I'm impressed on how quickly you gather photons and process. Do you sleep or are a vampire? ;)

Wow! That is amazing that you were able to capture this faint nebula with all that LP around you AND from the Balcony! I think the long integration times you are able to get and your superb processing skills help that nebulosity shine thru. 

 

Curious to find out what kind of LP zone are you in - Bortle 5/6? What is the estimated SqM reading for your skies where you shoot? Reason I ask is that I am in Bortle zone 7/8 (SqM of ~18 at zenith). I thought I would not be able to get anything on such faint targets due to high LP. Cheers ..... Anil

HI Anil,

 

I am situated in a yellow zone surrounded by green. In 20 km away to north and south are bigger cities (red). With my Smartphone SQM app I measure 20.5 at the zenith in good nights but do not know how reliable that is. But that value is consistent with results I got evaluating my dslr images with the method of Samir Kharusi some years ago. Is there a method or a source to derive / measure reliable SQM values without expensive equiopment?

 

I feel quite restricted shooting RGB but with NB imaging that I do since one year it feels like shooting just through the LP and the haze as if it weren't there :-)

 

Cheers Pete

Hi Alberto,

 

we do not have too many clear nights here. But I have the setup ready to shoot on the pier in the shed outside and I am quite fast in processing. And I use APT, an MGEN and an MFOC that support my sleep. And I have a vibrating wrist alarm watch that wakes me up at median flip time because I do not fully trust the APT/MGEN auto flipping routine. I do not worry about possible damages because APT stops the operations if anything goes wrong with the flipping. But I do not want to waste frames when an error occurs while I am in bed.

 

So YES I do sleep and NO I am not a vampire grin.gif
