Getting great guiding tonight on my az eq6. Multistar guiding and a balanced rig really helps

Got to happy with that Zuts. I get pretty good results with the asi air as well specially with a esprit 120 fully loaded on my eq6 pro. Usually high 3 to low 4s

Thanks Kuz.

Yes, very happy. I am 'fully loaded' and waiting until dark. Tha AZEQ6 is great, but a bit heavy as a portable setup. So I am eyeing the AM5.

I escaped Sydney and am in Broken Hill ATM, nothing but clear skies here.

Cheers.

Sure you weren't guiding on a hot pixel? :D
That looks great. Very nice indeed.



Super, super, jealous!!

I was going to mention about guiding in a hot pixel as well
Those guiding numbers are ridiculous for a mass produced Chinese mount
Even with hyper tuning the best guiding Ive seen on an AZEQ6 mount is around 0.35 to 0.40 in good seeing
That mount is something special , look after it , it’s worth gold !!!

Thanks Guys,

I guess it is a keeper, I just wish it wasn't so damn heavy or more truthfully that I wasn't so damn old!

Zuts,
In regard to your incredible guiding I was wondering what your image scale ratio is between guide scope and main imaging scope
I’m assuming your using a guide scope and not an OAG
Mines about 4.2:1 on my 8” f5 newt using a guide scope
Cheers

Zuts,
Some nights I get 0.5 guiding at very best, but most nights I get 0.7ish. 0.27 seems exceptionally good! I’d love to learn more about your gear, such as the ratio Martin requested. Also, was your guiding calibrated with darks?

Kind regards,
Stéphane

Guide camera

I own a ZWO 120 MM, but was testing a friend's ZWO 290 MM and I can't remember which one I was using that night.

Image Scale

If you mean FL ratio then the Esprit 120 has a FL of 840 plus a bit more with the 1.01 flattener.

The guide scope is a Baader Vario with a 60 ml objective and 250 ml FL so around 3.4 : 1

Guiding

No dark calibration, 2 second exposures, multistar guiding with ASIAir plus

Cheers
Paul

Image Scale or Pixel Scale
Camera pixel size uM x 206.3 / imaging scope focal length mm = Image Scale ( expressed in arc sec per pixel )

A) Main imaging Image scale
Imaging camera pixel size x 206.3 / imaging scope focal length = ?? arc sec per pixel

B) Guiding Image Scale
Guide camera pixel size x 206.3 / guide scope focal length = ?? arc sec per pixel

Imaging to Guiding Image Scale Ratio
B to A
General rule of thumb for acceptable image scale when guiding is 5:1 or lower

so 3.36 : 1

Excellent image scale guiding ratio
Definitely supports your unbelievable guiding numbers
👍👍
