Recommended Posts

Here's my attempt at the Fireworks Galaxy.
Details:
Explore Scientific ED152 CF APO
ASI 2600mmPro
Chroma LRGB Filters
TS/Optics 1.0x Field Flattener
iOptron CEM70EC Mount
ASI290mm Guide Camera w/ZWO OAG-L

30x180sec Lum = 90 minutes
15x180sec ea. RGB = 2hrs15mins.

Total Integration Time: 3hrs45mins.

Captured with NINA from Wee Thump, NV - SQM 21.35, processed with PixInsight

The last time I photographed this galaxy was back in 2017 when one of the many supernovae in this galaxy popped up. Here's a little short video I made showing then and now.

I managed to grab another night of data on this subject. Slightly tighter crop.

08-26 & 8-31/2022

L- 50x180sec = 2hrs30mins.
R- 32x180sec = 1hr 36mins.
G- 34x180sec = 1hr 42mins.
B- 32x180sec = 1hr 36mins.
Ha- 18x600sec = 3hrs

Very nice fireworks Greg and excellent YT blinking the 2017 SN. This galaxy has been on  my bucket list a long time, but I've never imaged it. I was planning to derig the QSI from my C14 to start my planetary imaging season, but you've now got me thinking about this one again.....🤔

thats a lovely Fireworks Galaxy,  very deep with hints of surrounding IFN

Thanks Peter. Not quite as sharp as yours but not bad for my smaller budget rig. I too was quite surprised to see what I thought was IFN with only 30x180sec Lum

It's not too late Geof, I know we are nearing the end of galaxy season but this one is still high enough to get at least 4 hours of data on it each night.

I've been checking it out as I have a possible clear window tonight. I don't get astro dark until ~10pm from my location and it transits at around 11pm, so yes, maybe I could get a few hours on it tonight....🤞

Hi Greg, here's what I got a couple of nights ago....
