Dear IISer's,
I just got the ASI-2600MC Duo, along with M48 filter drawer (for 2 inch filters) and a kit of spacers. But I have not gotten any filters, yet. My scopes will be my 4inch Genesis and 5inch NP127is, on the AM5 with ASI-Air Plus. My backyard sky in Camberwell is Bortle 6. No opportunity to hook up the 2600 yet, and the weather here has been cloudy/wet.
My main question is regarding choice of a light pollution filter(s). My initial interests are the obvious ones eg. M42, Eta Carina, Trifid/Lagoon, but also star fields such as Omega and 47 Tucana globulars, Jewel box, Pleiades etc.
I was thinking initially about a Broadband filter such as the Optolong L-Pro, and just see how that goes, because the L-Pro will allow me to make a start on both nebulae and star-clusters. And from what I can tell from Youtube, the L-Pro seems pretty good and not that far behind many Narrowband filters.
But can someone enlighten me about the LED lights in Melbourne, I know I still see a lot of yellow/orange street lights (mercury/sodium I assume), but is LED lightning bad now as well ? If this is the case, then does this mean Broadband filters are becoming more useless, ie. the best way to get star clusters is to go outer-rural to Bortle 1, 2 or 3.
And if LED is getting bad in Melbourne, does that mean imaging from Camberwell I really should only be looking at Narrowband filters ie. L-Extreme, or L-Ultimate ?
Thx, Fox
