I'm looking for advice from some of you EAA veterans on increasing visibility of DSO's.
I've had some moderate success with EAA in my bortle 6 neighborhood and I'm eager to improve my skills and setup. Lately I've noticed that when I attempt to observe nebula I get a wonderful, sharp image of stars tightly focused but no nebulosity at all. I use a 152mm f/5.9 with IR/UV cut filter and a 80mm f/7 unreduced. I control the setup with live stacking on the ASIAir pro. I've also used Sharpcap in the past but I do not plan to switch back to it.
I've tried with both a asi385mc and also my unmodified Nikon D5100. I have confirmed that my goto's are centered. I've played around with sub time and it has not made much difference. I have a few ideas but I'd like some feedback before I take my next step. I am considering:
- Experimenting with a light pollution filter. I have a L Pro that I can use with the asi385
- Adding a L Extreme to the train
- Modifying the Nikon
Any advice on the likelihood that any of those strategies might improve my EAA views of DSO would be welcome. Thanks!
