Thanks for the response! So... my next question though is what do I enter into the guide software? It asks for the focal length of the guide camera....is it just 120mm? or some calculation of both the guide cam's 120mm and the guide scope's 120mm?

So I have the ZWO 120mm mini for guiding... and I have the lovely ASIair which I think has actually given me more problems than it's solved. Anyway I have an serious issue with guiding...

I can't manually choose a star to guide. When I enter "looping mode" and touch one of the stars, I do indeed see the green box and then a green circle around said star..but when I click to start calibrating, it basically says 'screw your choice' and it picks some other tiny faint star at random. I'm using this on iOS and Android and I get the same thing...

Calibration then fails after it picks it's crap choice of a star telling me 'it hasn't moved enough'

3. I don't know if I have a good focus... I have to attach the extra black piece to it, and it's hanging on by a thread literally out of the back of the scope that I have. Is this normal? This seems like a very very extreme positon as it barely has room to be tightened into the scope..Is this normal?

I have this scope:

4. The ZWO is 120mm, but it's attached to the above scope, which is 30mm.... In ASIAir's interface it asks for the guidecam's focal length...Is it the base 120mm? or is it changed by the 30mm scope I have it attached to? What would be the number that I put into the ASIAIR?

This one is the ir/uv cut - the ccd version.

Again Thanks a bunch...ugh.. now I already ordered the regular IR/UV filter, but without the LP..ugh, now I may have to return and reorder the CCD version

Apologies. I read the post and I thought the link was to an advert for a filter. Re-read again and I can see your honest question! But yes, you can have LP filtration as well as IR/UV cut with the same filter. The IDAS D2 I use for example has UV cut up to 400nm and IR cut after 700nm.

 

Thanks so much!

So what about this one:

It doesn't say anything about IR/UV filtration...but it does say CLS...

Most decent LP filters have IR/UV cut. Astronomik CLS-CCD and the IDAS D2 LPS for example.

A bizarre first post imo...but welcome anyway!

lol, I'm curious why it's a bizzare post? Lol but thanks for the response...So would you say that it's just better in general to go with the LP filter over a normal IR/UV filter? Since it cuts both ?

So...a question...let's say you want to shoot in a slightly light polluted area...but you also want to use the IR/UV cut filter...how can you use both then? You can only apply one filter at a time...so are is this a sort of 'pick your poison'? So you can't have IR/UV filtered along with Light pollution as well?

For example here:

https://expertphotography.com/best-astrophotography-filters/

There's a ton of great filters...but how is it possible if you need a light pollution filter because of the area you're in..but you also want to cut IR/UV ? It seems like you can only do one at a time.

Thanks all..
