Just for the test, for others, not for yourself to use, maybe others would like to have a flattener only, so if you tested with yours and it worked perfectly then maybe people will avoid the dedicated one.
Ok will see what i can do, though another chap in this thread already tested an Altair flattener, a couple of posts up.
i dont mind though and have another reducer i can try at the same time.
Now the thing I cant decide is how to proceed now with the dedicated one, i sent my comparison with the Tsred279 to Sharpstar asking if they can explain whats going on, or if they are in the process of making an improved one but not had a reply to that, i think they did himt to this the last tike i contacted them in December about it.
But say a new improved one was released tomorrow i doubt they will let us swap it, but then again if the current one isnt fit for purpose, should i be asking them or the supplier for a retun, or is 5 months too long for that?
Thats the issue buying astro gear in the UK as we get so few clear nights to test it all.
the dedicated one works great for narrowband, but my main reason for purchasing a fast triplet and reducer was for wide imaging of broadband targets, things like M31, m45 and the faint IFN stuff in cepheus. Now i find I need to either use my CLS filter to mask the issue, but potentially also block the wavelengths of the faint stuff as that filter blocks most yellow, or alternatively use a 3rd party reducer in which case i have paid £200 extra for the dedicated reducer which will then become a paperweight :-(
