So i am planning to put together my camera , rotator , filter drawer and in my qualqulations i will be -0.45 or -0.55mm of the required 55mm spacing..

Is that error going to give me problems in my images ? 

I just got my Zwo Asi2600MC Pro and i will buy two filters , one broadband and one narrowband....

So i decided to be , the Optolong L Pro or Idas D2 and the Optolong L extreme...

My problem is money 🤣 so i need your advice on which filter shall i buy first....to start with...

I don't understand why the Chroma LoGlow is so expensive? 

I am reading this topic with a lot of interest because I am on the same path of choosing the correct filter for my new Zwo Asi2600Mc pro which is on the way.... Since I live in Athens with Bortle 8-9, for sure I will buy the Optolong L extreme for, lets say, short of a narrowband imaging(I use to image with an Atik 383+mono) so I know already that I am not going to get the same Nebula details that I would like to...

but I think that I need also a Light Pollution filter that will act as a luminance filter that I can put on top of my narrowband images...and also be able to shoot some Galaxies. 

Do you think that is possible to do that?

Unfortunately I don't know anything about NUCs.

If, however, you are willing to do without Windows, a (very cheap) alternative is using a Raspberry Pi 4 4GB (which I have been using for quite a few months, or even better the newer 8GB version) and the KStars/EKOS suite (planetarium plus everything you'll ever need to control all your gear). If you are not much into Linux, there's a precompiled image/package (Astroberry) that comes with KStars/EKOS already installed and a lot of other astronomy related useful software.

All you need to do is flash the image on a Micro SD card and attach a mouse, keyboard and monitor (needs to have HDMI input). If no external input is used, the Astroberry defaults to hotspot when you boot up and preconfigured with VNC Server. All you have to do is install VNC Viewer on another computer and then you'll be able to remote desktop into the Pi and configure your software/gear. Default IP of the Astroberry can be found on the Astroberry Wiki.

As I said, I have been using this solution for quite a few months (since March) and never had any issue with any of my gear (Sky-Watcher NEQ6, Nikon D5300, joypad, ZWO ASI 224MC, etc.).

I am also interested in a raspberry pi 4 but I can't configure how I will put this small motherboard all together in a box to make it work.... If its not a big trouble can you post a couple of photos to get an idea? 

Hello to all just a question because I am in the same path of buying an Nuc.... Is it very important if it cant work with 12v and needs 19v? 

Did you try different slewing speeds maybe ?

Perfect

Many thanks

Is it necessary to do a 3 star alignment before running plate solve ? or just a polar align will do ?

Excellent image! 👍

So you actually take the frames while on the fridge ?

I never understood how we can put a camera on the fridge really ☺️

Was it easy to remove the amp glow ? Was it very annoying ?

Nice image Andy , I was wondering if you could give me some info about your scope , bortle scale of your area because from what I see unfortunately I can't reach my budget for the Asi2600MC Pro and my next choice is the 294MC Pro....Amazing but I am still surprised by the images I see from this camera !

I bought my Esprit 100ED fro FLO without having a test and it is perfect !!! One of the best telescopes i ever had.

Hope you sort it out soon Dave... 

Thank you, my problem is that these dual band - triband or quad band filters dont come out in 36mm so the only option is for 2inch which ofcourse more expensive 😩

No 1.25 inch mounted and 31mm are not the same size as the 31mm is all filter but in 1.25 inch the filter mount is measured not the clear apperture which is 26mm at best. Once mounted even the 31mm filters are 29mm at best due to the ridge they sit on inside the wheel. You will need 36mm filters I am sorry to say. 

Thank you Adam for explaining this to me....anyway I was thinking it's not going to work since they were vignetting on my Atik383l+ mono that has smaller sensor. I use to have 36mm filters....

I think that a filter like the Optolong l extreme will make a difference on imaging results since I live in a city.

Thank you Dave , I will pair it with an Esprit100ED and with WO RedCat51.....it will be undersampled with the RedCat51 but wide...

I was checking the Astronomy Tools website to see what kind of filter size I can go with and the minimum recommendation was for 30.8mm if I am not mistaken.....Does that mean that a 1.25" filter will not cause vignetting.. ?

Here is 47 x 180s and a raw sub from my QHY268C - same chip.

Excellent image/result....!

About 2 seconds onto a USB3 port.

That's nice 😊

Thank you Gina , I appreciate your answer , deffently I will never compare the results from a mono ccd with a Color CMOS unless technology goes so far...but if I can get descent results to be happy with I will spend to buy this camera and a filter as well 😀

Thank you for your answer , could you tell me how long does it take to download an image ?... approximately...
