Hi all - does anyone have experience with clip filters (click-in) to Nikon D7500? I need a flexible narrow-band setup ...

I have found this: https://www.stcoptics.com/products/astr ... 7187271833

Anyob´ne with experience with that?

Og what about this one: https://www.cyclopsoptics.com/astronomy ... kon-aps-c/

Is there any other narrowband clip filters that you can recommend (I also have a Nikon full frame D750, but that one is not astro modified as my D7500)?

Thank you for your answers "redfox1971" and "Louis D". I also have an on-going discussion with Celestron support - the above is good input 🙂 I will be trying to use an eyepiece ... thanks again!

I have just recently bought a Celestron 0,63 reducer for my Celestron 8" SCT - and I get some weird artefacts when using it - please see attached pdf.

Any of you out there experienced something like it? Do any of you have a solution for it?Reducer artefacts.pdf

I cannot seem to get my gear fully functionable and tracking precisely enough. I have a 8" Celestron Schmict-Cassegrain on an advanced VX with Celestron OAG og Lacerta MGEN autoguider. I am trying to run with reducer for getting the full benefit of the 2000 mm focal length.

I suspect that it could be the parameters for “AG speed RA/DEC” that I should play with. I run a calibration before each shoot (for individual stars - and getting up to 91%).

Anyone running a similar setup that would be kins enough to share the MGEN settings with me?I would also like to know which parameters are used for in “Live view”, for “Gain”, “Exposure” og “Threshold”.

Any help on this matter would really be appriciated.
