I should add that the house has only recently been completed and is still empty yet. It is on the market if anybody has a lazy $1.6m. Maybe you could buy it and remove the light for me. 
My garden is quite small so there is not a lot of options for trees/hedges behind the observatory. I'll probably resort to something like Martin has done with a screen that can be quickly put up and taken down.
I'm more of a galaxy guy than a nebula guy. I was under the impression that narrow band filters, like the Optolong L-Enhance, were only really good for nebulae. It would cut out most of the signal from the galaxy blowing out the acquisition times. What narrow band filters do you use, Martin? |
I don’t use filters for galaxies, they mess with colour
The 2600MC has an internal UV/IR cut filter as it’s protective window which is all you need
Sydney Bortle 8 , I’m limited to 60 to 90 sec subs for Galaxies
South Coast Bortle 3, I usually use 180 to 300 sec subs for Galaxies
I use the Antlia ALPT 5nm Dualband filter for all emission nebula, it’s the best OSC narrowband dualband filter I’ve used so far. Far superior to my old ZWO and better than my recent L Extreme too.
Cheers
Martin
