IC1871 data from 3 years apart

[carastro]

Also known as the Whirling Dervish

I was disappointed in my recent effort at this target that the Oiii was overwhelmed by the Ha in part of the image.  

So I decided to go back to the image I took in 2016 where the Oiii was showing, and decided to combine the two images.

Both taken from my Home Bortle 8 location in SE London. 

So this is a real mixture:
Taken with completely different equipment slightly different orientation and different scale, so a Crop was necessary. 

2016 ED80 and Atik314L (3 hours Ha, 45m Oiii and 1hour Sii)
2019 SW130PDS and Atik460EX (3 hours 20mins Ha, 1 hour Oiii, 1 hour Sii)

Totals 
6 hours 20mins Ha
1h 45mins Oiii
2 hours Sii

Grand total 10 hours 5 mins

Great processing Carole. For me this type of image, the colour, the bubbling nebulosity, epitomises deep sky imaging. Superb.

Thanks very much Adam.

Pretty good to get something like that from a light polluted zone, Carole.

Thanks Andy.  It can be a struggle sometimes, and some targets impossible.

Thanks Simmo

That's an improvement Carole, greater depth to the colours.  Old data is never wasted ?.

Thanks Barry, I am mystified as to why the missing Oiii data showed up last time, with similar amounts of Ha and Oiii each time.  I wonder whether it's because my LP has got worse because I know that Oiii can be a "no go" from here with some targets.  Also we had LED lights installed since the last image.

Any thoughts on that?
