 Here you can see the starting point of the latest M101 - The first image is luminance data and the second is the combined RGB data - This is all pre processing. I thought it would be interesting to see the start and finish point.
Click here to read a little more about the processing involved  Details:
Mount: Mesu 200 Telescope: ODK10 Camera: QSI683 withBaader RGB filters and 3nm Ha Astrodon filter Luminance 54x1800s RGB 25x600s in each filter Ha 17x1800s This is 48 hours worth of data.  On the left hand side is the data from 42x1800s exposures and on the right is 9x1800s - You can see that there's a big difference in noise and also in data quality. Below is a close up comparison of the background between the two lots of data.   More data to add to M101 - This is 42x1800s totalling 21 hours. I think I'm looking at getting about 30 hours in total in luminance.
 A review of the MallinCam All Sky camera - everything you need to make it work and how it's been going after 3 months of use.
www.swagastro.com ......................... is my new domain name. But you don't need to change anything, you can still visit me on www.swagastro.weebly.com (where you will be automatically redirected) or www.swagastro.com  As it's galaxy season, it's only right to attempt something with the ODK10 that I've not only done before, but something that is a bit of a frame filler. M101 fits the bill and this is the start of the image 9x1800s exposures in luminance. Loads more data required!!  This is a target I have wanted to do for years with a longer focal length. This is VDB141 or the Ghost nebula. It is only 5x30m exposures and already in that 2.5 hours the ghost is starting to show.
This is going to be really long term as I want only the best data and lots of it. Because it's not narrowband data it is very much affected by the moon, so once that is out (however small) then this data will not be added to. Follow my blog here for the following............. Ongoing projects
