First Light Trius SX674C with Altair Wave 102 - Pacman Neb


Recommended Posts

This is my first light with the Trius SX674C combined with Altair Wave 102.

Three hours of imaging at zenith but avoiding a meridian flip.

18 x 10 min subs

Guided in PhD
Captured in Maxim DL
Stacked and Processed in PI
Slight tweak in PS

Very nice Doug, im going to ask anyway but was this a OSC capture ?

Im doing the very same target right now in NB with an Altair as well :-) but the baby 80.

It's a great object to see on your screen Doug, look forward to seeing more of your work keep it up.

Thanks for your comments.

This was a OSC.

I'm working on star reduction within PixInsight.

I would love to do LRGB, but work gets in the way, so OSC gives me quicker results.

When I retire in the distant future, I'll move away from OSC.

When do we expect to see your NB image

I'm currently working on processing 3 hours of Bubble Nebula at the moment.

Hi Doug i may & try to get it done tonight IF it stays semi cloudy otherwise i will be collecting more data.

I understand completely RE OSC, horses for courses & all that, i guess i like a challenge as i went for mono (sometimes i wish i hadn't :grin: ), tbh i didn't even notice your stars but i see what you mean, i still havn't looked at doing star masks etc but i'm sure with the present weather there will be plenty of time to learn.

The Bubble is a great target i'm sure you will be chuffed with what you see.

Thanks for your comments.

Olly, my time constraints are more working away from home or leaving at the crack of dawn to get to work.

I agree that mono would be quicker and produce a better image, but I like a bit of colour.

I recently purchased the Trius SX674C and Ian King did try to persuade me to go mono.

Now I've got my set up working after a year of issues, I didn't want to add a filter wheel at this stage.

Kirkster, I don't think the focus was out as I'm using a Lakeside Focuser without automating the process and using Maxim to achieve the lowest FWHM value. I think the stars are slightly bloated and I'm trying to master star control in PI.
