Back in May I had a fun night vision observing session with my C11 which I wrote up here:
In the replies to that post Cnoct asked me whether I had viewed/taken a pic of the Soap Bubble. I’d never heard of this object and did a bit of research to find out that it was only recently discovered in 2007/8 by CNer Dave Jurasevich. It seems it is a rather faint object.
Anyway I was intrigued by it and so was Ray (GeezerGazer). Ray challenged me 😀 to see if I could see/take a phone pic of it with my night vision equipment. It was obvious that it would need dark skies, aperture and a fast scope to have a chance of success.
This weekend events came together and I had my 16 inch f4 dob at a darkish site with good clear skies forecast so I thought I would make an attempt.
I decided that my system to try this would be my harder gen 3 monocular, coupled with a 55mm plossl and a narrow chroma ha filter. I was also using a Televue paracorr which increases the scope f ratio to 4.6. My 55mm plossl would reduce the speed down to a relatively fast f2.2
The skies weren’t quite as dark as previously (I measured sqm 20.7) and the half moon came up around 11.30pm so there were some obstacles but at 12.45am I managed to get this image with my huawei phone with 50 iso and 25 second exposure.
Checking this apod link which Ray kindly supplied to me together with detailed star hop to get to the Soap Bubble I realised I just (and I mean just!) managed to capture the Soap Bubble on my image (I couldn’t see it live visually).
Its a bit of a hunt to find it in the image (the apod link does help) but it’s right and up of centre...(Ray and Moshen have both agreed it is visible). I may have another go tomorrow when the moon is further out of the way.
