Kuma, Alrakis, 16 & 17 Draconis, some nice double stars
Summertime, gray nights....it got a little darker pretty late last night. Rightly so that I could only choose a few double stars and not some faint nebula. Add to that the bright Schiedam city-sky and a rising Moon and you're left with only two naked-eye stars: Arcturus and Wega. More were simply not there. Time for a push-to with Polar Scope Align Pro.
Polaris I can't see from my little garden. So then with the built-in compass / inclinometer just pretend I'm on Polaris. Those who are not strong must be smart and have a little guts. Confirm the fake alignment and off to Arcturus..... where I am a good 6 degrees off. Not bad for a casual alignment. To the phone screen and using the arrows and crosshairs to center the target on the screen. No stars other than Arcturus and Wega are visible. My scope points to a light gray area in the sky. To my delight, at the lowest magnification and a 3.2-degree field of view, I see a double star at the bottom of the image. Kuma aka Nu Draconis. Happy!
Recalibration is now unnecessary and Alrakis and 16/17 Draconis appear without fail using the little screen somewhere in the field of view. Funny thing is that in the little screen, the target regularly "floats" out of the center and then in another direction. Sometimes even a bit up and down. Must have to do with the various signals the phone receives. Alrakis and 17 Draconis require higher magnification. I put in 200+. To my surprise, the barlow lens that comes standard with the telescope ( after a flocking job on my part) delivers a nice, hard contrast image. Certainly not inferior to a barlow lens from a slightly more reputable source ( did not have a flocking job) . Even a fraction harder contrast.
Then I focus the scope on Epsilon Lyrae, this time just with the viewfinder, where the observed differences between the two barlows are confirmed. And so I bring my double star total for the evening to 5.
Sketches of the three double pairs, as seen through my refractor with a mirror-diagonal.
Satisfied, I clean up.

Re: Kuma, Alrakis, 16 & 17 Draconis, some nice double stars
Hi John.
Congratulations on theVROD . Wow that's some commitment under less than ideal conditions. If you can only see two stars, then you might do better with an alt-az mount with digital setting circles like a NEXUS or ARGO NAVIS.
I have a NEXUS on my 18" push todob . so easy. I need two alignment stars to calibrate the model. These work best if the stars are both around the 20-30 degrees altitude and separated in azimuth by 120 degrees or more. No polar or other alignment required.
Joe
Congratulations on the
I have a NEXUS on my 18" push to
However, in the absence of that, you'll have to make do with Arcturus and Wega. My 18" will nearly centre objects in the 20 arc minute field of view of my Denk D14 using widely spaced calibration stars. I suspect if you have less precision due to Arcturus and Wega being closer together, but the wider field of a refractor, you'll have no problems.No stars other than Arcturus and Wega are visible.

Re: Kuma, Alrakis, 16 & 17 Draconis, some nice double stars
John, nice drawings, and unfortunately made easier (well not as many stars to record) by LP .
Nice creative alignment too! I have an equatorial mount and light/wood-fired heater pollution (in Canberra AUS) can make finding Sigma Octans a challenge. I too often use the compass/inclinometer rough alignment method if I am doing visual observing, and like you, usually find it is good enough after aligning on the first bright star, to find a second, and then it is usually pretty good. For photography sessions I use Polemaster (the camera is reasonably sensitive) for PA, and building the mount model is then straight forward.

Re: Kuma, Alrakis, 16 & 17 Draconis, some nice double stars
@OzEclipse
Thanks....
Not for long I will have better precision with a new device called MeMstar. It is French, still in development and they are working on an I-phone udate right now. It has a precision of one degree, more than enough for the 7 or 4 degree field of my viewfinder or the 3.2 degree field of my wide-field refractor. I belong to one of the hundred pioneers ( they call it "ambassadors" ) that is testing the first batch. Still, I'll remember Nexus, just in case.....

Re: Kuma, Alrakis, 16 & 17 Draconis, some nice double stars
@scribbly
Thanks,
Yes, it seems like the same alignment method for visual observations.
ThePS Align Pro app is not one of the best; its advise is to recalibrate on a nearby bright star every time one hops to the next target. If one does, no big issues will occur. It's not as reliable in the sense that you don't know exactly how far away you are from your goal. It varies from spot on to several degrees off. But at least, it works reasonably. Better than nothing at all and looking at a bright evenly lit grey sky.

Re: Kuma, Alrakis, 16 & 17 Draconis, some nice double stars
I am glad to read that the new system is working well for you John.
A great session and sketches.
I purchased a Argo Navis years ago due to the continuing light pollution from Bratislava and have been very happy with it.
