  1. From the album: Photos from Bury

    Date taken: 21 and 23 March 2020. Camera: Astro-Modified Canon 600D. Telescope: SW Esprit 100 with Field Flattener and Baader U-HCS filter. Mount: AZ-AQ6 mount Image: 60 light subs (3 minute with 15 sec interval) with master dark, Flat and bias each made from 80 subs. Comments: The Pinwheel Galaxy is a favourite goto object for me. There is good detail here but not quite beating my image obtained in Salisbury a few years ago. There is no substitute for a dark sky. The larger FoV of the Esprit 100 does capture the smaller galaxies in the background well though. I may try to add more subs to this one.

  3. From the album: Deep Sky Objects

    M101 - Pinwheel Galaxy OK Sorry to post the same image twice but this just demonstrates the power of better data processing tools. I came across a piece of software called Astra Image Plus (http://www.astraimage.com/) which lets me adjust things with a bit more control and pull out more detail, so I have re-processed .

    From the album: Deep Sky Objects

    M101 - Pinwheel Galaxy Taken over 2 nights to trial a new guide camera (QHY5L-II mono). The guiding was much better than with my old camera. However I'm still experiencing camera timeouts. I think I have resolved this by running the camera on a dedicated USB cable rather than through a hub, but time will tell. I'm fairly pleased with the result given the ligher skies that we have at this time of year with it never really getting truly dark.

  5. From the album: Deep Sky Objects

    Messier 101 - Pinwheel Galaxy Taken with reasonable seeing and the best guiding I have managed to date. I still need to get the guiding better but we are getting there. This is in monochrome only as I used a Skywatcher Clear Sky filter to deal with the light pollution. I'm very pleased with the end result all things considered.
