William Optics Zenithstar 81 - First Light (NGC6188)

After a bit of trial and error i was finally able to get everything up and running at the weekend and attempted to capture some Ha data on NGC6188 (The Fighting Dragons Of Ara).

Unfortunately, not long after starting my imaging session the clouds rolled in and I had to pack up for the night.

It may not be much but, with only 15 minutes of imaging time I was relatively happy to come away with my very first deep sky image.

Looking forward to capturing a decent amount of Ha, SII and OIII data on this target over the coming weeks.

Imaging Camera: ZWO ASI183MM PRO

Thanks mate.

Yeah, it's a nice looking scope. It's taken me a little while to get everything set up how I wanted it. I just hope I can do it some justice and capture some half decent images, haha

I recently got one of these too, and use it on the same mount, same filters and similar camera (asi1600), and did the same image as this on one of my first nights out i think yours came out a bit nicer, though! Thats an amazing result from 15mins!

Thanks.

It was quite frustrating to be honest. Spent so long getting it all set up only to have to switch everything off just as I was getting started.

I think the images were too underexposed at 180s so I'll probably increase them to 300s at the next attempt.

Forecast is showing clear skies this Friday.....fingers crossed.

Hi Graham.

If you can get that detail after 15 minutes, imagine 15 hours!

Well done.

Peter

Thank you.

Yeah, forecast for tomorrow and Friday is looking good so I'm hoping to capture 3-4 hours of Ha data.

Thanks mate.

Gain was set at 200 on that one although I started again last night and captured 2hrs at Unity again (111) with 600s exposures.

Almost a full moon but Iím hoping to capture another 3hrs on it again tonight since thereís no cloud forecast.
