Enjoy reading these observing lessons Alex.

I have a question or 2 about filters for nebulae. I have a cheap Kson 2” UHC filter that serves my purpose just fine. Only used it a couple of times so far but do they all give a colour tinge to what you’re observing as this one does?

A new shopping centre has been built about 1km from my house – getting bigger by the week – and they have installed those nice bright LED lights in the carpark that has noticeably brightened the sky from my backyard. Do I understand correctly that my filter will not be able to block this light as it is a full spectrum type of light being emitted?

Thanks in advance and looking forward to the upcoming planetary lesson as they are a favorite target for me.
