Warts and all lagoon and triffid

Hi everyone

This hobby allows me to disconnect from much that
Is my otherwise my involved life.

This image is....as usual..warts and all.

Polar alignment is a little out, I know.......

Wide..... yet deep enough for my current skill set.

It leaves me happy yet even more excited for
what is to come.

Details below:

Canon modded 1100D.
Canon zoom 75-300mm @ 200mm.
No filters.
50 x 70 seconds light frames
70 x 70 seconds dark frames

Skywatcher StarAdventurer unguided.

Stacked in Deep Sky Stacker

Processed in Snapseed.

Once again ..thanks for looking.

Looking at it...

Note to self...

Perhaps close the aperture down a few notches ?

Hi Paul, round stars would improve your image enormously, so I suggest
either improve your PA, or cut your subs back to about 40secs. What
aperture, ISO, etc did you use? The sweet spot of an 1100D is 1600.

Quite dramatic and not bad for a zoom objective - mine old Canon as wonderfull as it is for terrestrial has a strong chromatic abberation when doing stars - yours holds much better. And I totaly get you - this hobby keeps me sane when the live gets too hectic

Hi Baobab,
I'm surprised that your Canon has CA, no Canon lens I've ever owned including my present ones display[ed] any. Even my cheap Yongnuo
50, 85, and 100mm are CA free apart from a tiny bit on the Moon.
