I've gotten myself a bit confused and need some clarity if you wouldn't mind.
Can you explain "integrating" and "frame x of y" seen in broadcasts?
Also ALS/Sense Up and the wireless timer on my Jr Pro?
I'm confused as to what these are exactly and how they are used together.
Thanks!!!

Rick, I don't know what you mean by "frame x of y". I have never heard of the term. 'Sens Up' is an 'Integration' measurement: 128x is 2 seconds integration (NTSC) (2.5 seconds in PAL) 256x is 4 seconds integration (NTSC) (5 seconds in PAL) 512x is 8 seconds integration (NTSC) (10 seconds in PAL) etc etc Why these numbers are used is because NTSC broadcasts at 60 frames per second and PAL broadcasts at 50 frames per second. But as for 'integration' it is easier to show you a ready posted explanation: www.qcuiag.org.uk/videointegration/

Yeah, I knew I wasn't explaining this well... maybe this image will help. Its a composite showing all the elements that are confusing me and making me unsure of what combinations of settings have what effects. I'm not sure which are exposures, which are integrations which are on or off chip -- and thanks for the video.
I am assuming that the red and green are from MiloSlick / AstroLive and are therefore off-chip. The purple, the wireless timer that plugs into my Jr Pro, I'm not clear on how it should be used (or shouldn't) with those settings (and frankly with the blue and yellow settings internally to the camera).
I'm sorry, this is probably a really stupid question that I've somehow just missed.
Thanks for the link... that helped a bit.

Ahhh ok Rick.
The RED is telling you how many seconds to go in your integration.
You have chosen a 45 seconds integration. The 12 is telling you how many seconds have ticked off towards the 45 seconds. If you watch it you will see it count up to 45 seconds repeatedly.
The GREEN is your stacking status. It is saying that you have selected a stack of 3 and that it has done all 3. So you have done '3 of 3'.
YELLOW is your cameras Sensup Setting (or integration) without using the Miloslick software settings. It is saying you have the camera set at x128 which is 2 seconds.
BLUE is a Shutter adjustment for an electronic Security lens: ALC (Automatic Level Control) is a shutter speed with a 'fixed' value. Sensup has to be turned off to make it work. ELC does the same as ALC except the shutter is fully adjustable to match the amount of light the lens catches (Aperture). Neither of them are a worry to us when we have the camera inserted into a telescope.
As far as your hand controller (PURPLE) I've never seen one and know nothing about them. I only use a PC to control my cameras (with Miloslick).

Hi, I frequently use remotes like these on my DSLR's when taking shots not connected to a PC. They do the same thing basically, take shots at predetermined intervals, sets time between shots, duration of exposure, number of exposures etc. but are all separate exposures. I have two of these in my all night - all sky boxes, two DSLR's set to take 30-second exposures at two minute intervals from dusk till dawn. Everything is inside the box with a heated acrylic dome etc, all sky cam using DSLR's. I also often use them just as a remote shutter control, handy when taking eclipse shots-takes the exposures automatically.
Clear skies... Shevill

As I remember it Rick, if you choose any exposure more than 2 secs in the software,(as in the pic) you must programme the wireless timer to the same amount of seconds. The delay function will set a time delay before the timer starts,keep this at zero. The long function is the amount of exposure in seconds, set this to the same exposure as in the software. The interval function sets the gap between exposures, keep this at zero. Start the software and the wireless controller at the same time to sync the exposures.

Thank you guys for the replies and trying to help.
Shevill, my Mallincam Jr Pro is not the PC version -- it came with the wireless timer combo as the solution. I did buy the PC Control cable but apparently it cannot do the timing via the Mallincam Jr Pro control software and I still have to use the wireless solution. Allan, my Jr Pro only goes to 128 (2 seconds). I often run it between 5 and 7 seconds, but have run it up to 23 seconds before in my testing and experimenting. That's with 128x set in the camera. By software do you mean Miloslick or the Mallincam Jr Pro software?
So with Red and Green... Is the integration per frame? Meaning 45 sec for each frame of 3 frames (image updates come every 2m 15sec)? Ken, I borrowed one of your images for this... I have not yet taken the Miloslick plunge, partially due to this confusion.
So with yellow Sense Up, does it's integration then get multiplied by the Miloslick integration? Do you have to watch the sum-total?
I'm not sure if the wireless timer is doing exposure or integration. Or maybe I'm just confusing the two.
Sorry I feel like I'm being dense.

I may not have this exactly right as its been a while since I used the Pro and I generally used miloslick but I'm fairly sure the principal is the same. If you don't use the wireless timer then the longest exposure you will get will be 2 seconds no matter what you set in frame capture box. With the pro, its the wireless timer that controls the exposure so anything over 2 seconds has to be programmed into the timer and started at the same time as the software. You can set any amount of seconds in the software but unless the timer is used, you will still only get a 2 sec exposure. As an example, if you set senseup to x128 and take a 2 sec exposure you see 10 stars. Then you set 20 secs in the software and take an exposure you still see 10 stars. Then you set the timer to 20secs and activate it. The timer then controls the exposure of 20 secs and when 20 secs have accumulated you see hundreds of stars because it is now a 20 sec exposure not a 2 sec exposure.
Red and Green... Is the integration per frame? Meaning 45 sec for each frame of 3 frames. The image should improve as each frame is added. When all the frames have been added to the stack, the image will stay like this until you stop or change anything. (I think)

Thanks Allan, I think this really helped. I am going to experiment with your scenarios... That's what I think I'm seeing happens and that limit may be behind a lot of my confusion. Sorry for the delay on the reply... Starting a new job this week and had to travel my first day
