How do they attach to the focuser?  Presumably they screw on in place of the flattener  ..

thanks

Dave

I'd imagine so as it's a reducer/ flattener

Sky-Watcher have released new optically-matched 0.77x Reducers for their Esprit 120 & 150 triplet refractor telescopes 🙂 

Sky-Watcher 0.77x Reducer for Esprit 120ED Triplet

Sky-Watcher 0.77x Reducer for Esprit 150ED Triplet

 

 

Very nice. I really hope they're going to do one for the esprit 100 too.

I want to know how they found that deer in the forest so far away, and the bird.

and f5.5 not ( fast) enough? 

Not compared to a Samyang at f2

Here's my SHO palette attempt with your data which is very nice and clean indeed. Maybe i need an astrophotography holiday. All processing done in Photoshop.

Thank you for releasing this data and letting us play with it.

Your HA data looks fine to me. Noise starts to show in any image if you push the data too far.

but I still am struggling to combine them and get a good result

Maybe you're trying to push the data too far?

Thanks!

Just looking at the stars again, hard to decide if they are on the green side or not, I ran HVLG (high setting) but I guess it could have missed a bit

Must be my phone then. HVLG always does a good job for me 

Your blue stars are slightly green (or it may just be my phone) other than that you've got a very nice image there 

Fingers crossed we have clear skies

Finally!!!! It's been delivered after an 8 week wait. Typically now there is cloud for the next week.

 

That's a very long wait indeed. I'm sure you'll be happy with it. I've had 2. I sold the first one and regret set in before I'd even posted it.

I hope you enjoy it

That's an excellent image for an un-modified DSLR.

A fine m31 you have there, maybe a tad over saturated on the colour but still very well done

This could be a good buy for you with some budget left over for a flattener.

Big moon, haze, dew and fireworks. Perfect time to test the Samyang 135 and ZWO183MM combo.

You've produced a fantastic image with a wonderful 3d effect.

Yeah I do.

I've no idea why they're over correcting. Maybe try aiming for a higher and lower adu, see if that makes any difference.

Your flats are over correcting. I've always just used my luminance flats and they've always worked fine. 

I've never taken separate flats for other filters.

Very nice and a pretty cool idea 

That looks finished to me, it's beautiful. 

How much deeper do you want to go?

Adding data to vdb141 whilst trying to block my next door neighbors kitchen light.

Has the time/ date/ location changed when you updated?

My guess is that it's something to do with calibration as I cannot see how changing the offset could result in this.

I may we'll be wrong though, I have been many times before 

I'm a very happy chappy.

It's alot bigger in person but I now own a lovely esprit 100ed with flattener.

My dual rig is almost complete

A very nice well made bit of kit but rather over engineered with masses more adjustment than needed (  IMHO )  better  and cheaper to make something.

I'm really bad at DIY so I'll just buy something
