NGC 6164 - mode data added

Finally got a night to image and add data, now the wisps around NGC6164 are starting to appear.

Very well done. The outer OIII shell is faint and hard to capture.

Thank you.... I'll add a few more hours and see what results that brings, though I'm pretty satisfied with it already.

Jeff,
Great effort on a difficult target, some fine detail coming through
Well done !!
Is your Bintel 6” an f5 or f6 ( mines an f6 and she’s a little gem, fitted a dual speed crayford focuser and replaced the primary springs with locally made heavy duty ones , I haven’t need to re collimate in over a year , its 5 years old now and mirrors are still pristine)

Thanks Martin.

It's a 6 inch with a dual speed focusser too. I am dreading the day I have to collimate as I've no real idea how to do it .. but like all these things I'll manage!

I know it’s a 6” aperture but I was asking about about focal ratio f5 or f6
f5 focal ratio means its focal length is 750mm long ( OTA tube length about 800mm )
f6 focal ratio means its focal length is 900mm long ( OTA tube length about 850mm long )
I chose the f6 over the f5 to reduce Coma a bit and with a longer focal length can attempt most of the brighter galaxies from Sydney Bortle 8 ( Centaurus A , Sombrero, M83 , NGC 253 , Pavo and a few others )

I can assist you with Collimation later , once you’ve done it a few times it’s a 5 minute job , easy ( not so easy with a 12” like my Goto dob )

Cheers

F6 then, FL is around 900mm.

Good choice 👍

Thanks
