Hi there!
I am considering buying LRBG filters + a filter wheel to complement to my DMK41 and ASI 120MM on a SW 10" truss dobsonian, for planetary imaging.
I have the old dilemma: buy soon and go cheap or save and wait to by quality gear.
Cheaper option: $369
Orion filter wheel set (incl. filters) (

More expensive option:
Set of Astronomik LRBG filters: $339.00

Orion Nautilus motorised filter wheel; $479

Of course another option would be to buy any of these second-hand or overseas.
An other option again would be to forget the filters and wheel and get a colour camera such as the ASI 120MC for around $300.00 (as I a bit bit concerned a bout the extra 20mm travel required on my standard SW focuser.
I have no experience with imaging filters, but I have been regularly imaging the Moon and Jupiter in mono for about a year.
Any advice and suggestion would be greatly appreciated.
Cheers,
Eric
