NEW StellaMira 90mm ED Triplet Refractor

[rsarwar]

4 x 1 mossaic. first time i did such a big one. almost 40 hours of data using Ha 3.5 from Baader and O/S 6n from astronomik + qhy256M. could not normalize the background evenly unfortunately.

My first real attempt with the hubble palette. So far I've collected about 8 hours of photons for the image.

I really like my StellaMira 90

Anyone know if a ZWO EAF will fit this telescope ?

Thanks.

It does.  Grant @ FLO provided some good insights on best fitting, so worth an email.  I ended up doing it very slightly differently (re-using the thumb screw) but still seemed solid.

That's great. Thank you.

Hi

Has anyone used a TSFLAT2 x1 flattener with this telescope ? Just wondering if it will give round stars into the corners on a APS-C sensor ?

Thanks

Aw c'mon! we're not talking nuclear submarine propulsion systems here!

Don't feel bad, I get the same answer from our venders in the States too.

The StellaMira 90mm ED triplet telescope is back in stock 😀

Is there a 100mm on the horizon?  Why is the 104 ED not for sale anymore?

We have a number of telescopes in the pipeline but are currently not able to share info. Sorry.

Lack of availability. We hope the situation for this model will improve.

First time I've used my gear for a few months ! Have I put something round the wrong way in my imaging train because my focuser need to be racked right out now and before it was around 30mm !

At first glance, I think your reducer is upside down 🙂 

If you emailed us over the weekend (we close for weekends) one of my colleagues will see and reply directly today.

Yeah I've dropped you an email, I think it is as well as stars looked weird

Yes. The reducer won't work properly when reversed 🙂

My latest effort NGC 7023 with the Stellamira 90mm as we had a run of a few clear nights lately. LRGB image stacked and processed in PixInsight and Affinity Photo. Ioptron GEM45, ZWO183MM. ZWO 7 position filter with Optolong filters, Astro Essentials 50mm guide scope with ZWO120MM mini camera. Captured with APT.

There are some nice images coming out of this scope 👍

Indeed there are 🙂 

Thank-you to everyone who has shared images made using their StellaMira 90mm. They are much appreciated 🤗

Hi, just wondering how the adjustment knob comes off. Mine arrived today and want to transfer my EAF over to it. Don't wanna break it before I use it.

If I remember right it has a grub screw that loosens and lets you slide off the coarse adjustment knob.

Can't find one.  Nothing on the knob. There are ones on the fine adjustment knob

Pretty sure the grub screw on the right doesn't do anything so whip it out and then you'll have access to the 2 grub screws holding the coarse knob on.

Yeah, you're right, I took a punt on that earlier. Was a bit worried at first in case it was a tension screw and didn't want to mess it up on first day.

Ok, first full night with my new SM90. Just wondering if there's any way via 3d printing or something else to get a graduated ring for the rotator on one of these. Never had a rotator before and now I've got 2 on the same scope. 

When framing in NINA it would be nice to check the rotation needed on screen and then apply the same accurately on the scope.

How was it ? 
 

I’ve had a run of unfortunate circumstances. Apart from just a couple of hours to set up and test the FF spacing when I first bought it, I’ve not been able to get out with mine again. Hopefully this will change in 2 weeks time, looking forward to actually using it. 🙂
