Trapezium in 10-second subs

[lukebl]

Hi all,

Inspired by Luis Campos's amazing images taken with his DMK21 in short exposures (see here), I though I'd have a go at the Trapezium myself and see what was possible with just 10-second subs.

Here's the result. I know the colour is a bit odd, but it looks interesting all the same and it is amazing how much detail is possible to squeeze out of just 10-second exposures. It's made up from 60 subs each of R, G & B, SXVF-H9, SW 250 f/4.8 Newt. It would be interesting to see the result with 10 times the number of subs. Who needs guiding!

how did you combine them? Did you use drizzle?

I stacked the R, G, & B subs separately in DSS, with 3x drizzle, then combined the channels in Photoshop. Just couldn't get the colour right, though.

It wasn't really intended as a serious image. I just wanted to see what was possible with 10-second subs, just 10 minutes total for each channel. It was also nice to resolve the Trapezium, which usually gets burnt out by longer exposures.

Amazing resolution! Inspiring too Luke!

Hi there Luke,

Really glad I inspired you to try that he he he

That's a really good result, the trapezium is nicelly resolved with pin point stars

You should try other types of small deep sky gems like the Esquimo, blinking, cat's eye, etc...

I'll be making more experiences in a near future, when the sky clears up here in Portugal that is...

Cheers,

Luís

This is exactly what I see with my scope but in GREY. Lovely photo.

Yes that is quite an achievement. I would not have expected that resolution which really is mighty impressive. You need an M42 to use it in, now! (or maybe you've got one?)
