Interloper with the Spanish Dancer

[Maurice]

Hi

I have started collecting data for an image of NGC1566.

I was surprised to see a weirdly coloured yellow/green 'star' in the data & became mildly excited when I couldn't see it in any of the stock images for this object on the net.

A SN search soon pointed to SN2021AEFX discovered on 4th December by Jean-Claude Merlin....missed it by 4 weeks....

Anyway, small low res crop at 50% full size attached here.

Usual RC14 set up with ASI2600MC camera etc..
3hrs total exposure (so far).

Cheers
Maurice

My apologies.
The discovery of this SN was on 11th November 2021.

Image tidied up a bit and is now full frame & 50% full size on Flikr:

Still only 3hrs. Hoping for more data soon.

There's a joy of discovery even if you aren't the first.


Supernovas are usually intensely blue-white. No stars, supernova or otherwise, should have a green tinge. Perhaps the image colour balance is slightly off.


Otherwise, congratulations on the galaxy, and congratulations on the serendipidous rediscovery.

Oh. I've just realised I've got the SN in my recent image too. Thanks :-)

This will look great when you are finished collecting the data Maurice. I look forward to the finished product.

Off to a good start there Maurice.
