Just gave this bubble a bit of a lift. F/5 makes for clear reflections. Upwards from f/5 there will be a stronger reverse reflection coming, I think, from the inside rear surface.
2013 ETC - Bubbles.
I made my own oilier than your average bubble mix for this. I would have liked a nice sky blue background but the reflections were greater the darker the background was. Hence the fence.
A little soap bubble inside a bigger soap bubble.
This is my first download from my new camera: Nikon D7000.
The D7000 just gives me an extra bit of everything, compared to my D90. Exciting to play with a new camera!
The Bubble Nebula (NGC7635) is one of three shells of gas surrounding the massive star BD 602522, the bright star near the center of the bubble. Energetic radiation from the star ionizes the shell, causing it to glow. This is one of around 300 of the most massive stars in the milky way.
The star is known as a Wolf-Rayet star, which is an O-type star that is nearing the supernova stage. These stars are incredibly hot — from 25,000 to 50,000 Kelvin (about 24,726 degrees Celsius or 44,540 degrees Fahrenheit) and expel their outer layers of gas at tremendous velocities (thousands of kilometers per second).
Image Details: This is a combination of LRGB and Ha. I was unable to use the data from the previous image. Maybe I will figure this out eventually.
I used Pixinsight exclusively for processing this image other than for stacking for which I used DSS as usual.
Luminance: 4x10mins bin 1x1
R: 4x5 mins bin 2x2
G: 4x5 mins bin 2x2
B: 4x5 mins bin 2x2
Ha: 9X15 mins bin 1x1
A synthetic luminance channel was created using pixelmath using the idea described here.
pixinsight.com/tutorials/narrowband/theory/en.html
Even though this is generally done only for Ha, I found good results using this method for Luminance.
R was also combined with ha using the same manner described in the paper above
G and B processed normally.
I had to do some pixelmath trickery to reduce the appearance of seams despite frame adaptation since the Ha and other frames weren't perfectly aligned. That issue is still visible but not too intrusive I hope.
I am satisfied with this image for now.
Camera: QSI 683 ws8
Scope: AT8RC with CCDT67 reducer
Guided with stellarvue SV50 and Orion SSAG as usual

121034 at the limit of operation at the far end of the headshunt at Claydon Loop. It was forming the Branch Line Society's 1Z65 "Bubble & Squeak Tracker" railtour on 9th April 2017.
These are a bit samey so this is the last of these for a while.
This is how I do these soap bubble shots.
I have a piece of curved perpex (I bought a flat sheet and bent it in the bath by pouring boiling water onto it) which I covered in tissue paper. A domed light tent basically.
I have 2 flashguns either side.
I blow the bubbles in from under the side of the perspex using a tube.
I made a loop in a pipe cleaner about 1 cm across. Then I wrapped it around the end of the tube and angled it up and then down. This allows it to catch a good amount of bubble fluid and because of the downward angle of the pipe cleaner it means gravity can still feed the loop even if the blow pipe is angled upwards. This lets me blow large/lots of bubbles. Using just a tube I found I could only blow small or very few bubbles at a time.
I took this whilst watching someone demonstrating a bubble blowing device. On processing I could see the reflection of the ground within it, reflected upon itself.
