Getting Started...

Post by RMay » Thu Jul 26, 2018 4:34 am

Greetings all. I got a new ASI224MC and have it connected to my Questar 3.5... Tried shooting Jupiter but all I get is a white disk, which tells me it's shooting very hot or something else is amiss. Will look at a few videos, but glad to be on board. I'm not very technical, but learning.

Cheers!

White disk is likely result of over-exposure. You have to lower the exposure time and/or gain if it's already short. Then finetune focus and done.

Try this, exposure time 20ms, increase the gain from 0 to 350( until you get enough brightness of jupiter)

I’ll try these settings/suggestions tonight and let you know how it works out.

Thanks for taking the time to respond; it’s greatly appreciated.

I have been on the phone with the vendor 3 times this week. Their customer support rep has been stellar; I just can’t get my camera to work right. Jupiter looks like crap, the moon is horrible and it’s been a very disappointing experience so far. I’m going to keep trying, but I believe I’m going to have to ask for support from you good ZWO folks in another few days if I can’t seem to get past ‘go...’

Im using a Questar 3.5 and I’ve taken better pictures through my iPhone... that’s what’s so disappointing... >sigh<

"White Disk" - means that you are over-exposing Jupiter. Jupiter is BRIGHT - because it is just past Opposition.
Work to backdown the Exposure from 20ms to 10-5ms (using a DSLR we usually are shooting 1/120th-1/250th second to get a decent exposure). Also ensure the Gain is at a reasonable 100-200 level.
Once you have Jupiter at a decent Exposure (even if blurry it should be orange-ish instead of white), then you can work to improve the Focus.
Then, work on Exposure again until you get the most Detail possible (and don't expect all that much Detail in raw captures - that comes after Stacking and Sharpening).

Let us know how this turns out.

Stay tuned...

Success!!!

Post by RMay » Tue Jul 31, 2018 5:10 am

It’s working!! I connected the camera through the Questar’s axial port and used the eyepiece to guide viewing. Works great! Got Jupiter and Saturn. Even used AutoStakkert to build a few images from groups of ten that I saved (to avoid using too much PC memory).

Lots of learning and fine tuning next, but I’m on my way!!

Thanks for all the help and kind words!

Ron
