| Hi, I already own the l-pro and l-enhance. I would like to add an l-extreme-ish to my collection but I find the optolong a bit expensive for my current situation. Can anyone recommend something similar but cheaper in 1.25” format ? Like |

| I think the zwo duo-band could also be an option. It’s cheaper than the sv220. I’ll try to find some reviews Like |

For comparison: Yes I saw that after posting, really not impressive. I’m pretty much set on the svbony. I’d love to complete my optolong collection but these things are expensive in Canada. The l-extreme is over 300$ while the svbony is half the price at 150$. Edited ... Like |

| I finally went with the SV220 which I just ordered, along with a SVBony UV/IR Cut filter and a ZWO EFW Mini. The filter wheel is why I was looking for a cheaper alternative to the L-Extreme. I had to keep my total under 500$ CAD Thx again for the comments and suggestions. Like |
