finally a guided image (ish)

[gonzostar]

Hi

Finally the other night myself PHD2 and autoguider are playing ball! Part of what was the issue before was polar alignment. Polemaster has helped big time there. Would people still then do PHD2 drift alignment? Then using guiding assistant to remove backlash 3 times. Is balance in dec best way to help get rid of this?

Only managed to stack a couple of 3 minute images together with my equipment of m42. I have noticed people using high aggression in RA and Dec

Other frames where taken but jolts in  image where i think i moved around setup to turn camera off! Not sure how to resolve turning camera off without jolts!

Anyway hopefully things are slowly improving

Any advice gratefully recieved

Cheers

Good job getting guiding working, that is one of the more annoying parts.

Dec just guide in one direction then backlash isn't a problem.

RA make sure you are East heavy then backlash isn't a problem there either.

 

Not sure why you are turning the camera off, are you using an intervalometer?

Cheers Dan. I am using a canon 450d DSLR with a release cable 

Sometimes DEC fluctuates form zero line so i alter north south, In terms of aggression in RA and Dec is it better to have high 80-100 or lower arond 50? I have seen screen shots where it is high but then a you tube tutorial says keep it down? Whats your opinions?

I think it depends a lot on the ratio between the focal length of your guide scope and that of your imaging scope and what pixel scale you are working with.

I used to use an OAG but have started using a DSLR lens as a guide scope so the settings all had to change.  I guess it is whatever works for you.

Slow Dec drift in one direction isn't a bad thing, guiding works best if it is correcting in one direction all the time rather than ping ponging from side to side.

 

 

I think an intervalometer would be a good investment, either that or set up a laptop and control it remotely.  You don't want to be touching the camera as going anywhere near the mount can upset the guiding.

I am using the Orion autoguider (5.2microns) with the 50mm guide scope. I am imaging with a 8"SCT (F6.3) with a canon 450d camera

I am thinking of  a OAG but see how this goes first. There is alot of trial amd for me more error  

Also will invest in a better intervalometer. How do you arrange all your cables?

I think an OAG can work well on an SCT but it can be a pain to get the spacing right if you are using a reducer.

 

My guide camera is mounted to my imaging camera so its USB cable goes with the power and USB for the imaging camera.  My focuser is connected to the USB hub built into the imaging camera.

The ST4 cable hangs down on its own.

If you are using a Canon then I can recommend Backyard EOS for image capture. You won't need to go near the camera once connected.

Might also be worth trying apt to connect to your canon. The free version has loads of usable features and I highly recommend it.

Is it free?  As said by a Yorkshire man! Mananged to get a good hour off tracking on friday. Results not fantastic but getting better. Finding out about balance now in Dec.

[PeterCPC]

No not free but it's not a lot of money and you can try it first before you buy. https://www.otelescope.com/index.php?/home/&page=bye

APT is a great software, for both CCD & DSLR use.. and a fantastic Future of APT is, "PLATE SOLVING"... beside many other futures..

and not even expensive.. " 18.70 EUR "
