Another NGC1333 in Perseus For You To Peruse.

[StuartJPP]

I spent Friday (15th) and Saturday (16th) collecting some additional data for my NGC1333 from last year. I havent' been out for ages, despite the clear weather recently.

Since the village I image from changed from Sodium to LED lighting recently I kept the IDAS filter to try and keep some consistency in the subs, but there was certainly a difference in the colour, could have been conditions as well as the neighbour's Xmas light wonderland

Both nights weren't great overall, but there were periods of good transparency. I plodded along regardless as I wanted to "finish" off NGC1333 once and for all (though we are never really finished are we?).

Baader modified Canon 6D at ISO 1600
Canon 500mm f/4 L IS lens at f/4
Avalon Instruments M-Zero
Polar Alignment using homemade PoleMaster
PHD2 for guiding using QHY5L-II-M and QHYCCD MiniGuideScope
APT for image acquisition, GOTO++, framing, plate solving, and dithering.
SQM (according to Unihedron SQM-L) was ~20.77.

Total of ~120 subs of varying quality of 300 seconds each (totalling ~10 hours)

Imaged just outside Horncastle in rural Lincolnshire...

A fairly quick process, the raw data is still a bit noisy but a lot easier to process now with additional data. Will spend some more time on this.

 

Typical guiding:

 

Setup on Saturday night during a clear spell:

 

Just prior to packing up at 02:10 as freezing fog came in:

 

Dew heater doing its job:

 

SQM of 20.77 apparently.

 

Thanks for looking!

Thats a cracker Stu... plus a sparkly frost covered lens   I love nights like that!

Glad to see you out imaging agains Stuart.  Your NGC1333 just gets better!  Love the dust!

[gorann]

Amazing image and effort!

I had -14°C last night and frost everywhere except on my heated front lenses, but of course I had the benefit of naturally cooled and noise free DSLRs. I should have taken a picture of the deep frozen triple rig but I was just too cold and tired when I finally closed the roof at 7am.

Excellent dslr version of this area.

Very nice Stuart. I do envy your rig, the Canon and Avalon work nicely together.

Fabulous image Stuart. I really like the subtle dust lanes, they make it stand out & the whole image has a slight 3D effect. Well to my eyes and my Adobe RGB screen, that is.

Fabulous!!!!  Well done Stuart, incredible details you've got in there.

Yes I got caught by that freezing fog too and had to pack up at 03:00.

It is a blessing in disguise, it took quite a while for the lens to dry up completely despite using some dessicant/moisture absorbers as I didn't have my lens cleaning kit with me. All fine in the end though. The tripod and mount and knobs were frosty too...

Thanks Barry, I have added enough to this now so this is as good as it gets, though I will play with the data again.

We were just below freezing, about -4, so a good 10 degrees warmer! The coldest the camera reported was 6C, so yeah, who needs a cooled CCD

Thanks, DSLRs have some use still

Thanks Ian, yes I like this setup and it is pretty stable now, so it has allowed me to add to data from last year. Quick to set up even though I hadn't done so for about >3 months.

Although the subs started getting a tiny bit brighter between them, the last sub was almost completely white, at which point I knew it was time to pack up.

Thanks Peter, hopefully I can now move on to a different target.

I like that Stuart..... that's a very classy image indeed ??

[gorann]

I have now processed one of my images from Sat-Sun at -14°C on (just posted) and I could not find a single hot pixel, so frosty equipment has its advantages......

[Shibby]

Lovely image. Good depth, detail, star colours; it's got it all!

[MartinB]

Wonderful image Stuart esp given your LP

[graemlourens]

Very impressive and very mysterious. I love it!

It does have it's advantages, but in the UK we don't have too many nights like this, usually it is just grey and damp

Oops, should have stated this was taken in rural Lincolnshire, sorry about the confusion. I almost never image from Leeds, quite pointless unless doing NB.
