John thanks for the great video but I had a question…I still don’t understand why you are leveling the DEC and RA at the beginning of the process. Why not just point the mount north with a compass and then use PSAlign Pro to do the rough PA?

Can you clarify something. When you first aligned in the day you were roughly pointed towards Polaris. Later you said you point the scope to 90 degrees away from that. Do you mean the mount is now aligned that way or you are moving the scope using RA/dec to that point?

Thank you for the video. Im living at the south hemisphere, i might give this a try. I have a question though, since i live in an apartment unit, i only have view of the east from the balcony, nothing else. I cannot even point to the zenith or 90 degrees. Is there still any hope of being able to do drift alignment in that situation? Balcony has a roof, so i dont have any view 90 degress upward. Thank you

@real_astrotard 3 жыл бұрын

You need to be able to see 90 degrees orthogonal from celestial north (in your case celestial south) which is the point where the meridian crosses and equator. If you can only see east I think you're screwed.

@rexcao4454 3 жыл бұрын

thanks for the video, if say I use the 3 star alignment to improve the accuracy, and auto guiding will compensate some level of tracking error. Is it still necessary to do another drift alignment?

@real_astrotard 3 жыл бұрын

3-star align orients your mount so that it knows it's way around the sky. Polar align (or drift align) dials-in the alt/az adjustments so that your guiding is pristine which results in pin-point round stars rather than oblong football shaped stars. So you need to do both.

I have EQ3-2 mount. When I click "Drift" it results with an errror "Please connect a camera and a mount". I don't understand it - why does it require a mount to be connected? The documention says: " You can still drift align without an ASCOM connection" - I understand that I can drift align without connecting the mount. Is that right?

@real_astrotard 4 жыл бұрын

Drift Align tool in PHD2 connects to your mount via ASCOM and sends signals while measuring star drift to determine the RA/DEC error graph. Thus it requires a connection to the mount to do this.

I cannot see Polaris because it's behind the wall. But of I buy an AZ EQ6 normally it would be possible to align automatically with 2 stars alignment with Deneb and Altair for example. Isn't it ?

@real_astrotard 3 жыл бұрын

2-star align orients your mount to the stars but you still need to polar align to "dial-in" the mount to result in good guiding & round stars while imaging.

It wasn't obvious to me why you bothered setting the rings on the mount at the start. I'm assuming that when both are pointing to 90 RA and 90 Dec that they are pointing at the crossover of the meridian line with the celestial equator? it is fantastic to finally understand how to use those rings, as I have wondered why they were included on the mount that I have as this is the first instruction I have seen for setting them up.

You need both and each serves a different purpose. The 3-star align will make your guiding better resulting in pinpoint round stars. The plate solve simply finds a target in the sky and has nothing to do with how accurate your guiding will be. You need both.

If you're doing your astrophotography in your kitchen, why not shorten the tripod legs so you don't have to lift your equipment up to head height to mount it? Easier, safer, and you avoid the step stool if you need to adjust a dew heater or want to take dark frames, bias, and white frames.

@@real_astrotard Yes, indeed it's probably the best benefit. Thanks for the video on getting a polar alignment without having a view to the north and during the daytime. What many don't realize that even if you use autoguiding to correct for polar alignment error, the image will have rotation around the autoguided star, so stars at the edges of your image will trail a bit. The only way to eliminate that effect is to be sure the polar alignment is as accurate as possible. Clear Skies !!
