Last night it got really cold (8C !) so I took advantage of good astro weather and added RGB data. Unfortunately, for a strange reason, got only 15 minutes of usable blue as the rest of the subs were shifted by about 1500 pixels so I discarded them.
Looks great Suavi bottom left.....is that the tilt your talking about?don't think I would of noticed If you hadn't mentioned It.
Thank you Louie.
Star shapes slightly change depending on the orientation of the telescope - nice and round when pointing approximately straight up. So it has to be a flex. Would not suspect a FTF to flex - my Moonlite was rock solid...
Yeah,the QSI isn't a heavy camera.....this is what I use to see from the BabyQ's focuser,ended up sending that back to Tak and they beefed up the focuser.

I may try sensibly tightening all bolts.

Glad you like it Greg. It’s a small CFF (105mm f/6).
It is still a very lovely image Suavi!
I am surprised to hear that the FTF is flexing. I know I was getting a little with my refractor focuser but that was with probably more than twice the weight and wasn't a fancy Feather Touch. Maybe there is something that needs to be tightened a little?
I believe I found and hopefully rectified the cause(s). The screw at the top of the FTF was quite loose - so I tightened it a bit. I read that TEC recommended tightening this screw for heavier loads as they noticed some flexing with 3.5" FTF and this is supposed to help. Also, a ring holding the field corrector's lens in place was for some reason not tightly threaded in and the lens was moving a bit inside the corrector. I suspect this could have been the main gremlin. So hopefully, the next astro image from Prossy will have beautiful pinpoint stars across the entire image.

If all isn’t well and you cannot get it working, just send it down to me for a while and I’ll make sure I give it a good few months testing
Very nice image especially for a first light!!
Cheers,
Tim
Thank you Tim.
Its not actually the first light with this scope, but first from a new home and first “proper” RGB since previously I used to be a narrowband guy.

Thank you Colin for your kind offer. I am confident she is going to sing from now on, but asking just in case - should I send her with the mount as well since these two are a match made in heaven
Skies are really much better here in Prossy, at least when it comes to absence of light pollution. I could not see any dust donuts nor gradients even in 10min Luminance subs, so I probably could get away with not using flats at all. Flats were a definite must in Paddy in Brisvegas and it was often quite a challenge, even with narrowband imaging, to remove all artefacts.
The first night (of the two) was quite warm too - temp was still around 24C for the bulk of the imaging session on the first night.
Fingers crossed stars shapes will be better in the next image.
