How are you guiding? I only had a newt for a short while, but I could never get round stars with a guidescope. The stars improved a lot after switching to a OAG, but they were still not perfect (collimation, CC distance). After a while I gave up, and switched to a refractor

Oh btw, Sony does have the 585 in mono as well. I think ZWO are looking into it, so might be worth waiting a bit

I sometimes do EAA with my Samyang 135. I have the 585 as well, and I don't think you lose out that much to mono with this sensor. I also use it with my Altair Dualband filters. These work well even at f/2! The stars are horrible though, so starless all the way!🤣 Here are NGC1499 (30x30sec) at F/2 And M42 (106x30sec) at f/2.8. Gain 300

All my FLO stuff arrives quickly. Maybe not the next day, but two days tops. The gear always arrives with clouds anyway, so not like we're in a rush to use it! 🤣 My local postmen/women bend over backwards to help you out. Great service! But I guess a lot of that comes from it being the same people over several years. You all get to know each other.

Turns out it was dispersion. I didn't think it would be that bad at that altitude, but it was.

I thought I would give this a go with my C9.25, and it seems to work well. However, I noticed that I'm only collimated in red (I used an IR pass filter when collimating). Green is off, but blue is really bad. I used Capella, which was quite high at the time, so I don't think it's dispersion. Could it be the optics? Thanks!

Concern about load distribution on my system. (FMA180)

I bought one of THESE from TS before Brexit, but I'm sure someone sells them over here as well. Lots of holes, which makes balancing things sooo much easier! -
We must have different bad seeing! Mine doesn't produce images like that! 😄 Nice image! 👍

Where are you finding this great seeing? I just get a mess everytime I am out! 😁 Great animation!

Imaging with the Samyang 135mm f2
Chris-h replied to Uranium235's topic in Getting Started With Imaging
I had the Astrokraken, which was fine at first, but broke in the end. I now have one from Astrodymium (FLO sells it), and it is WAY better. Very solid. easy to attach a ZWO EAF, and you can mount a guidescope at the top or on the side. https://www.firstlightoptics.com/adapters/astrodymium-ring-system-with-zwo-eaf-asiair-mount-for-samyang-rokinon-135mm-f2-lens.html -
Amazing images!

I doubt you will have any problems 😀
