Hi I'm not sure what the object in the top right of this photo is. There is also something in the bottom left I am very new to astro photography so not sure if its something very obvious. It is also digitally zoomed quite a bit so the quality of the image is a bit low.
I was in Sheffield at 19:35:43 on the 06 May 2020 when using a bridge camera i spotted a quickly moving object at quite a distance away (50x zoom). It was followed by a grey smoke trail and was leaving the atmosphere at a slight angle. It was spotted looking NNW. The object's trail has no sort of flames. Could it have been a man-made object? Does anybody know what it was or have any information on it?
I took Olly @ollypenrice seriously when he claimed that 6" refractors are great galaxy hunters, so I let my EdgheHD scopes rest in the cupboard and put the Esprit 150 at work. These images summarizes the few clear night I had in February and March. RGB was collected with ASI071 (OSC) in most cases supplemented with additional lum from ASI 1600 MM (sometimes sitting on the Esprit 100).
Top left: NGC2903
Top middle: NGC4712, 4725, 4747
Top right: NGC3718 and 3729
Bottom: M96 and M96
Yes, I have already posted the images separately, so excuse the spamming but I thought it was nice to see them together. It also gives an idea of their relative sizes as all imgaes are on the same scale.
Comments welcome, including if I should put the 11" EdgeHD on the mount instead.....
I recently had my first light with my new Mesu mount and aimed the Esprit 150 at NGC2903. Combined with the he ASI 071MC with its APS-C sized chip this gave me a rather large FOV and therefore a rather small galaxy.
I kind of like the small galaxy in a large space, but still I started playing with ways to crop the image, realizing that there are indeed many different ways to do this.
I first made a rather standard crop keeping approximately the same image dimensions and the galaxy in the centre:
Then it struck me that it could look nice in a more panoramic view:
And finally, I started to think about the possibility to use the famous Golden Ratio (https://en.wikipedia.org/wiki/Golden_ratio) used by artists since Leonardo da Vinci. I first tried it in its simplest form by just placing the galaxy in the one-dimensional golden ratio position along the length of the image:
But this could also be done in two dimensions using the Fibonacci spiral, and to get it there I felt it benifited from a 180° rotation of the image:
Any more suggestions? What looks best, if any? Feel free to play with different ways to crop my image.
