New AP Right Angle Polar Scope
      #5500935 - 11/02/12 01:07 PM

I just got notified that the Astro Physics Right Angle Polar Scope is ready to ship.

I ordered one with the Mach1 Adapter. I sure hope it works like a TAK polar scope.

I don't think they are shipping till month end.

But they are taking 50% now.

I generally don't like to be an early adopter but this looks too good to pass up - placed my order a couple days ago and paid my 50%.

Looks nice and looks a far better solution than my Pasil I (first gen. and made by Losmandy). But unfortunately it wont work with my AP 400 mount because of the smaller shaft diameter...

This needs their i-phone app to tell you where Polaris should appear in the reticle when aligned for particular date/time. You don't have to rotate the RA axis to use it which is nice. On the other hand, the pier would need to be level on the East West direction to not induce some error. I thought about it, but my locations have some slope to them and between the scope and the bracket for the mount, it is rather pricey.

The ASCOM v2 Driver is supposed to give you the same information as to where to place polaris.

If this is anything even close to the Takahashi polar scopes then it's the deal of the century since you can just polar align and then guide for 15 minute exposures.

I also have the PASIL from Losmandy and it's so loose in the mount it's got to be around +/- 3 degrees. It's basically useless.

I especially like the right angle part since I tend to keep my mount low when imaging which means crawling around in the dirt to look through the polar scope.

I've got my deposit down and my hopes up!

I think it looks great but its too rich for me right now between it and the required adapter.
Also, its apparently only as accurate as the initial drift align you perform to calibrate the scope. Not a big deal, just make sure you've got a good alignment when you first align the reticle.

Can't wait for some hands on reviews.

That's a very good point. I didn't think about that. the mount needs to be perfectly level in the E-W direction otherwise the first drift alignment is completely useless.
My Tak scope has a bubble level. That seems to be a better system as I can polar align without the need for the mount to be level.

Thanks!
A $1.99 app would be a lot nicer though, especially after
what the polar scope already cost.

It's really quite funny to hear a gripe about an app that costs $1.99 in the same context of an Astro Physics mount. It's kind of like getting upset that an oil change on a Ferrari generally costs $2k at a dealer. You bought it, you got it and now you have to pay for it.

No offense to the budget minded here on CN; it's just that you can't really expect AP, Tak, TV, or any hand made, high QC hardware to be cheap.

My last company had a Cessna Citation Bravo Jet and I remember my boss coveting a Gulfstream V. We couldn't afford it but that jet kicks *BLEEP* nonetheless.

I thought that the complaint was about the fact that no android app is available.
However I am very interested in first reports about the polar scope. Theoretically it should work great but I wonder if it will indeed be as good as the tak one. Btw If I remember well I had to buy tak align for my Tak mount.

The polar finder takes the place of the cable run. I'm not giving up my cable run on the Mach 1 given my field experience with polar alignment scopes. The alignment leaves just as much precision polar alignment work to do as if I had just eyeballed north when I set the mount down.

At least AP has the app to mercifully reduce the "Where's Polaris supposed to be?" Conundrum. But given how close the reference (Polaris) is to the axis, there is a lot of intrinsic error which can't be reduced without a far off-axis reference to get the clocking more accurate.

Anyway, while performing the trials which ultimately convinced me cable pass-thrus are the best use of that space, I made an alignment target. Enjoy.

Greg, i think you missunderstood what i said/meant.
I dont have any issue at all paying for a $1.99 app, its the fact its not available for Android, i dont want to
spend another $100 or more on a used iPad just to use it.

I'm just curious, I just received a Pasill4 and haven't had a chance to use it yet. Is this new angle polar scope going to replace the need to drift align? Will it be that accurate? Otherwise, isn't the polar scope only used for a for 30 seconds or so to quick align anyway?

I have not used the pasill4 yet but it seems pretty inaccurate and wobbly compared to the tak. The new ra polar scope claims to be a lot more accurate.
It will be only as accurate as the initial calibration and subsequent leveling of the mount in the e-w direction. I think it would be prefect if it was rotatable and had a built in bubble level

Hi Faron.
I followed Howard's suggestion about fine tuning the Pasill4L and this past friday I had my first light with the mount.
I did a 30 second polar alignment and it was precise enough to give me excellent goto's. Also the drift seemed to be minimal and very easy to guide out.
So thumbs up for the Pasill4 after the fine tuning!

I just had quite a bit of discussion with George and Howard from AP- long story short, they say the right angle finder is good enough to do away with drift alignment hell.

That's great Andy! Tonight was the first opportunity for me to use my Pasill4. However, I only used it to put Polaris in the field of view of the polar scope. I probably won't have to use it much at all.

I purchased an excellent program called Alignmaster, I can't say enough about it. After only a few mins of polar aligning with the software, I was amazed at the accuracy. I'm still learning the whole package and my gotos are dead center already.

There wasn't time for a complete imaging session given the never ending cloud cover. I managed to take a 10min sub of M45 UNGUIDED to test it out. There was only the the slightest amount of rotation. The center stars were perfect. Once I add my autoguider to the package, this mount is going to be fantastic.

I'm ready to image!!

Yes I am familiar with align master. It's a very clever program. If I remember well the only issue that I had is that the mount had to be perfectly level on order for it to be accurate. Well, not really an issue but I would prefer to to have to worry about leveling the mount.

Hi Rich,
Yes that't what I was told too. However I think the PASILL4L gives me enough accuracy that I am able to guide out any residual drift plus I don't have to worry about setting the mount level int he E-W direction. I can see how a more accurate alignment would be necessary if one wanted to shoot unguided, but other than that the standard polar scope seems to be sufficient for most imaging purposes. What do you think?

I would love the new right angle scope.

I have the PASIL4L and its okay but I was never able to get it centered properly so it didn't shift when you rotate the scope to get the big dipper where it should be each night. i tried all the tricks with tape, spoke to AP on the phone, etc. Never got it aligned all that well. Maybe its just me

I've always ended up doing a full drift alignment with or without a polar alignment scope. I am still personally at the point of needing to see a polar scope give an alignment good enough to do that on the first try.

The time-wise reticle in the new AP alignment scope makes a lot of the guesswork as to where Polaris should appear go away- so I'm not saying what they are doing is impossible, it's just I've had a lot of disappointment in the quality of polar scope alignments. The worst effect is swirl in the image, which becomes a bigger problem the wider your field of view is, so it's not really fixable by guiding alone.

I'm wondering how hard it is to change reticles in another polar finder just to be able to watch the alignment accuracy and see if the AP method by itself really is that accurate.
