TSS Photo of the Day
Bubble and Co
Hey everyone . As mentioned in the title, this image is of the Bubble Nebula, Cassiopeia Salt-and-Pepper Cluster, the Northern Lagoon Nebula and a faint Claw Nebula. It was taken over four nights with the SW72ED, 0.8 reducer/flattener, IDAS D1 LPF and modified Canon 750d in Bortle 7 skies and near a big LED street lamp. It's 156 x 150-second exposures @ iso-400, stacked in DSS with flat and bias master frames. The camera temp was around 32 deg C on average, so pretty noisy. Hopefully, I'll add some HA when the new filter arrives and when it cools off a touch. I hope you like it

Nice image Gmetric.
It will be interesting to see the comparison with your new filter when it arrives.

Thats a great image. For a 750D at 32c you have handled the noise really well. Its a great FOV .

Re: Bubble and Co
Thanks, Steve. Having been on a hiatus for a while and followed the fantastic progress you've made, I've been itching to get back into it. I'm hoping to move on a similar trajectory as yours as you seem to have gotten yourself into a situation where you are producing absolutely wonderful images. I can't speak for anyone else, but for me, It's motivating and inspirational.
Thanks, Marius

Re: Bubble up close for fun
Reprocessed close up of the bubble for a bit of fun. It might be a bit overcooked ...What do ya think?

@Gmetric I am not a technical expert, and I don't know what it should actually look like, but (for me at least) it looks much more defined and colourful.

Re: Bubble and Co
I don't think you are over cooking yet. In the wider field images I like the second better also as the definition is better. I thought a little about whether it was truncated at the low luminance end but decided not.Gmetric wrote: ↑Fri Oct 15, 2021 6:22 amTechnical expert or not, I appreciate your comments and feedback Thank youButterfly Maiden wrote: ↑Fri Oct 15, 2021 6:18 am @Gmetric I am not a technical expert, and I don't know what it should actually look like, but (for me at least) it looks much more defined and colourful.

Re: Bubble and Co
Cheers, nFA Appreciate it. I prefer the second of the wide field images too. Indeed luminance truncation would impact the perception of contrast and I felt the first image lacked contrast and seemed a little flat. Hence, the second image.

In fact, I could create an artificial luminance image and see what happens when added. Were you thinking along those lines? Thanks again
