Odd issue

[Camelopardalis (Dunk)]

Are you sure you didn’t get a hair or an eyelash on the sensor window?

Back in my cold-fingered DSLR days I had frosted it over a couple of times and the stars get much more diffuse. Yours shows a much more distinct halo.

Wonderful advertisement for the idiocity of push-onitis - imaging through bad atmospheric phenomenon.

The NGC 3132 stuff came out just fine

Dunk, RTFQ - the camera was not removed or disturbed from the prior 2.5hr run on 3132, so no way ANYTHING got in there.

As I mentioned WAAAAAAAAAY back in post No1 (I think), the temp SUDDENLY dropped to 5.7° (was 8°, and that is why I rechecked focus), so I suspect the front that came through was happening just then and I was getting pre-frontal atmospheric disturbance/ice/vapor...

The SBIG cooler percentage was 78% prior to this change, and during the change, it dropped to 54% cooling - so, the cooler atmosphere was aiding and abetting the cooling.

If anything it's a bad advertisement for SBIG Anyway, another EP size dew strip on the way to preheat the camera nosecone...

What was it? Push-onitis

That's a prime example of $hitty Lewis Processing - aka The SLP Method

haha, sorry, was at work so quickly skim read.

I ask as I've seen this before in my own images when there's high-level thin cloud usually not perceptible to the eye.

All good H. Just funning with you.

Def stealth clouds/ice

I occasionally get that on the odd star with my old Q. Bright stars that are about half way between the center of the field and the edge. Mostly yellow will do that. One bright line going through. Maybe it's a TAK thing.
