Whale nebula

[Kevin Phillips]

The image of the whale nebula was captured using a combination of equipment:

- HEQ5 mount for stability and tracking

- 714mm Horizon duplet refractor for capturing the cluster's light

- ZWO 294asi colour camera for imaging

- L-Pro filter to enhance the image quality

- Guiding system to ensure accurate tracking over the long exposure period

The image was created by combining multiple 300-second exposures over a 6-hour integration period, and then processed in StarTools.

Guiding was below arc second.

Hi Kevin

That’s a very nice image of the Whale Galaxy NGC 4631. You’ve got excellent definition and very good colour, for what is quite a small and not particularly bright object.

Btw I imaged this target a few years ago but haven’t got around to processing the data yet…

Well done!

Thanks Tim

Very happy how it came out. 

Not a simple target by any means.

Thank you.
