April and M91


April will have come and gone by the time I get back to Observing. Combined with a hectic work schedule and a busy life Astronomy seems to be taking a little bit of a back space just at the moment. However, I did manage to get out on Thursday 12th of April and spent an evening with the scope and camera shooting.


The target was M91 which is a barred spiral galaxy in Coma. This is part of the Virgo cluster. M91 is also the missing nebulae from Messiers catalog and was miss accounted when originally observed in 1781. It was again observed by Herschel and cataloged as NGC 4548 and later assigned M91 in 1969.

The above image is a combination of 5 x 20 minutes images taken with the sBIG and FLT110. The image was processed in Nebulosity initially then with PS.

First Light with sBIG ST-8300C Camera


So I took the plunge and bought a new camera. Still trying to get to grips with it and enjoy the images which is produces. The camera is a sBig ST-8300C, somehow i think that i should have gone for the monochrome camera but everything i had read indicated that i would spend just as long imaging through the filters as i would with imaging through the colour camera.

The first image i took in a dark site was of m66 and m65 just to get a feel for the camera and is ability. I shot this object the other week with the Canon DSLR so it should be a good comparison. The image below is the result.

The images show that there is a lot of potential with the camera but there is going to be a need for a lot more processing in the images. I am really surprised that the sensitivity of the camera is not great and from the initial impressions it looks no more sensitive than the Cannon.
