UKAI Collaborative Effort - September 2013 - Eastern Veil
« on: 12:33:01, 28 August, 2013 »
The idea for a collaborative effort has been muted before but not really progressed beyond people saying they like the concept. The basic idea is that as many people as possible upload their data for an object to a common repository and then get to share in the full data set that accumulates. Yes it is fraught with complications but nothing ventured nothing gained and all that.

So as a bit of an experiment we have set up a Dropbox with sub folders for L, R, G, B, Ha, OIII and SII. If anyone wants access could they pm me an email account and I will grant access. If you can then upload calibrated FITS frames to the relevant sub-directory making sure you include the sub duration in the file name (putting the filter name in there too would be a handy check). Eastern Veil (NGC6992, 6995) was choosen as being of a scale and brightness that is widely accessible and good in RGB and NarrowBand. The image below shows how it should frame up in a range of scopes and cameras.

We will run this from now until the end of September (please only post up data collected in 2013) which should give some time to accumulate data following which we will see what people can make out of the processing. A lot of processing software struggles with combining data from different setups. Pixinsight certainly handles it so it may be that one of us PI users will do initial alignment of the various subs but we can face that when we get to it.

If it works we will have a nice dataset to play with on those cloudy nights and we will run similar events in future.

Two lots of Narrowband data on there now folks. Peter Vaseys most excellent Ha, SII and OIII stacks and my own from the last few nights making 20 odd hours in total I believe.

Could do with some LRGB  ;)

Hi,

It could be my dropbox account which is the standard 2GB but if I try to accept the shared link I'm told it will exceed my limit.

I've checked and have over a GB of free space, how much is there in the share??

I had forgotten a bout this.  Is data collected before September acceptable?  If so you can PM me with the Drpbox details if you want my data.  Some in LRGB and some in NB.

sounds like a plan!

I don't use darks with my stuff these days - just a collection of Bias frames... I'll upload calibrated with bias FITS

OK... 

NGC 6992 in Ha (1200s & some 600s), and 1200s both OIII & SII uploaded into relevant dirs (under sub-dir of psjshep)

All have been calibrated with Bias removed, (don't do darks these days) but NOT aligned (registered)

Hate to appear thick but... Where exactly do we upload them to?

Good Stuff

Just done a quick stack of Phi's, ChrisH's and my Ha data and got this. About 7 hours in all. Will have a go at the other channels when I get a mo

Chris,

Just curious but how have you stacked the data if they're from different set ups with different chip sizes and pixel sizes etc? DSS doesn't do that does it? Or am I getting confused.

Thanks,
Phil.
