Guest Posted May 15, 2021 Share Posted May 15, 2021 The star cluster M45, better known as the Pleiades or Seven Sisters, originally photographed on January 17th 2020. It was taken using a DSLR with 6 images at 2 seconds exposure, ISO 6400 and 300mm focal length. Link to comment Share on other sites More sharing options...
+Graham Posted May 15, 2021 Share Posted May 15, 2021 Nice bit of nebulosity showing up there Phil Link to comment Share on other sites More sharing options...
Peter Shah Posted May 15, 2021 Share Posted May 15, 2021 The nebulosity is starting to show after only 12s that shows a lot of potential......I dont know what kit you have (mount) but if you can increase the sub length and do lots more of them it will dramatically improve.

Unfortunately, I don't have a driven mount. If I go to 2.5 seconds I start to get trailing. One thing I have been experimenting with is reducing the focal length for these types of shots. For example, I have found that the Beehive (M44) shows better this way. I am getting the message that not everything DSLR-related is about 18mm or 300mm. There is a lot of room in between. Maybe a driven mount might be a possibility one day but, at the moment, ready cash is in short supply. Link to comment Share on other sites More sharing options...

Called a barn door tracker.. Very simple and will get you started. https://www.instructables.com/Build-a-Motorized-Barn-Door-Tracker/ not mine just one i found on google Link to comment Share on other sites More sharing options...
