Re: 47 Tucanae with 155EDF refractor

Eric Weiner
 

Roland,

So this image was taken with the retrofitted Ohara glass 155 or prior to the retrofit with Schott glass?

It sounds like this is an OTA you still have in your personal inventory. It must sincerely be a pleasure to have found a profession which you enjoy so much, have developed significant skill in, and have built a very successful business out of which produces products sought after and coveted by so many.

Does this portend your consideration of a future 155 production run, or are you reminiscing? I’m not privy to what glass is available or not, or even what glass is good or bad. I’m a simple end user. A quick search shows Ohara Japan is still in business. I suppose quality telescope owners should understand these details if they are available.

Regards,
Eric


Re: CP4 not creating a COM port...

That was it.  Not sure how the board worked lose, I am the original owner and have never dropped it. I reseated the board and now when I plug in to the USB port I get a confirming beep when I plug the CP4 in.  However when I open device manager there is still no com port showing up, there is an other devices with a FT32R device that says the driver is not correctly installed.  This device disappears when I unplug the CP4.  I do not recall updating a driver when I originally installed the CP4, so any assistance on which driver I need to update will help.

It was processed back in 2011. I have not gone back to the original subs.Too many other projects.

I did want to post this because the 155 is probably my favorite medium sized refractor and I don't use it much here because I have a 160 (which is unfortunately longer and heavier). The glass for the 155 ended up having more and more problems (glass made by Schott) so I finally threw in the towel and redesigned the lens to use all Ohara glass from Japan in our 160 EDF as well as all the other newer scopes.

Very beautiful Roland. Simply out of curiosity, is this the image processed in 2011 or did you use modern techniques to reprocess the 2011 subs?

Cheers,

Hi Roland, many here 'down under' would readily agree with you.   It's certainly been a goto target that my AP 1200 has settled on many times to show countless visitors.   We are very lucky to have Tuc 47 in our backyard!
Nice rendition of yours, too.

Cheers, Chris

Re: APCC move axis question

Ray Gralak
 

Hi Andy,

I finally found the issue! The MoveAxis was not moving the mount only when Pointing and Tracking Rate Correction are enabled and the mount is pointing within 10 degrees of the celestial pole.

Since your testing was done above 80 degrees declination, APCC purposely turned off pointing and tracking rate correction adjustments so the moves were never issued. That explains why, when I did my testing, the moves worked, as I happened to be testing away from the celestial pole. That also explains why I didn't see any tracking correction log statements in your logs, which made me think you had mistakenly had it turned off.

The new version I just posted (APCC Standard 1.9.0.4 and APCC Pro 1.9.0.5) fixes this issue.

Here are the zipped files.

I copied all the logs just to be safe but the ones that matter are the one with time stamp around 8:11pm on
8/31/21
I had to use google drive because the APCC file is too large to attach to this message. I have also attached a
screenshot showing the box for "Enable tracking correction" checked. I believe that is where I turn on tracking
correction generated by the pointing model, correct?

Re: Rookie Question

I know this is a AP forum, I am using a Celestron CVX mount right now, but I am on the waiting list for a Mach2. 
I also use a Icron Raven 3104. I mounted it to the dove tail plate with a piece of  0.125" aluminum plate just big enough to hold the Raven and a powerpole block
it mounts under the focuser of my stellarvue SVX 70T very nicely. I run one 12v cable to a powerpole connector block to power my Focuser controller, Imaging camera, and Guide Camera.
I have the power for the Raven 3104 running directly from a AC block on the pier. I have one USB running down to the Mount hand controller from the Raven, I also have a 50 foot Ethernet cable to the kitchen table in the house. I run the  USB cables from the Focuser controller, Imaging camera, and Guide camera on top on my aluminum plate to the Raven. so I only have 4 cables swinging around as the mount moves, when I get my Mach2  it will be even less because I wont have the USB from the mount or the 12v to the powerpole block they run internal to the mount.

47 Tucanae with 155EDF refractor

Roland Christen
 

https://www.astrobin.com/fu21m5/

47 Tuc in my opinion is the most incredible globular cluster in the entire sky. Located in the southern hemisphere, it is easily visible to the unaided eye and really pops with almost any optical aid from binoculars to large Dobsonians. The perfection of this glob is in the symmetry and gradual buildup to the bright inner core. In a way it resembles the beauty and perfection of Mt Fuji in Japan.

The image was taken with a 155EDF refractor, one of many scopes that Daniel Verschatse installed at his observatory complex at the Hacienda de Los Andes at the southern edge of the Atacama desert. The location was close to perfection as far as transparency and steadiness of the sky. Marj and I were fortunate to visit Daniel several times while he was still with us on this earth. A more gracious host I have never known.

Re: Deep Sky Object Database for Non-Keypad Users

I have used Cartes du Ciel (CDC - https://ap-i.net/skychart//en/start) for several years now and really like it.  It integrates well with ASCOM, including the A-P V2 driver.  There are Windows, LINUX (a couple distros), MacOS, RPI, FreeBSD versions.  All are free.

While I have used UCAC, NOMAD, and GAIA star catalogs at times, the default catalogs cover all the obvious objects.  There are many other catalogs available from the above website.  One thing to watch for is where the catalogs are installed.  If you choose to install catalogs in a different folder than the default, then you have to point CdC at that folder on the SETUP -> Catalog configuration window.

CdC has a group.io forum... https://groups.io/g/skychart/topics

I also use Astrotortilla (a GUI for offline astrometry.net) and ASTAP for plate-solving.  Both work well; although I am more familiar with the former.  ASTAP is a bit faster, but not enough (seconds, not minutes) to make me use it exclusively. 

P.S.  1100 GT (non-AE), CP4.  I have never owned a hand controller and do not miss it.

You can use any planetarium program along with your keypad. I use SkyX to select objects I want to see, and use the keypad for centering, slewing and tracking functions, as well as parking, unparking, etc.

I have another "newbie" question related to APCC: I have been using the GOTO functionality of my keypad to slew to whatever object I want to look at. For those APCC users who do not have or use keypads what are you using ? I assume that you are using some sort of observatory control software (e.g. MaxIm DL or PinPoint) with some sort of object catalog, but there are many options.

Since I have the keypad I will continue to use it, but are there any particular advantages to going with observatory control software over the keypad ? If I did so it would most likely be via MaxIm DL since I already use that platform for guiding and imaging.

So I have been wondering the reverse a bit, whether I will eventually miss not having a keypad.  😊

 

I use Stellarium, which is free and pretty good.  I wanted to try Cartes du Ciel but despite trying twice could not get the additional databases loaded so it lacked a lot of details and images.


Stellarium though is pretty good.  It also will control the mount directly (via a telescope control plugin) or integrated with a session manager like NINA.  I image so my normal approach is to find targets in Stellarium, then pull the coordinates into the framing assistant in NINA, tweak framing and rotation, and then build a sequence to image it.  Stellarium will also show the current telescope location on its display, though I rarely use that aspect (i.e. I rarely actually connect the telescope directly to stellarium).

 

The biggest lack I would anticipate if I were doing visual observing is a convenient joystick type adjustment.  APCC and NINA both have buttons, but buttons on a windows display are awkward compared to a keypad to fine tune your pointing if visually looking through an eyepiece.  I say that theoretically, as one day I will find my eyepieces and try it.  😊

Hi there,

With PC software you can use plate solve functionality which for me was a game changer in my Astrophotography workflow. I use Astrophotography Tool which in my opinion is one of the best value for money acquisition softwares available. With APT you have access to Point Craft, a very capable suite of plate solve functions that automates centering of targets, meridian flips and much more. Of course there are many other programs that are even more complete than APT with Observatory control functions and automation.

The Icron Raven _is_ a good USB 3 option, but the REX remote unit is large (5.4"x9.1"x1.3") and heavy (2.1 lbs). Plus, it has an external power supply with an AC power cord and a 24VDC cable to the REX. I don't think the REX is suitable for mounting on dovetail plate.

I mounted mine on a wood panel on the south side of my pier: <http://astronomy.mdodd.com/observatory.html#SouthPanel> For scale, the concrete pier is 12" in diameter.

I loop USB cables from the REX to equipment on the mount. <http://astronomy.mdodd.com/observatory.html#CableManagement>

Hi,
I am using a AP 900 GTO mount, CP3 and keypad. The project I am involved in ask that I do a scan of the Sun with a spectrograph at various speed. Using the keypad or the ASCOM interface, I currently scan the Sun at 1X and 12X. Is there a way to get the mount to scan the Sun at 6X or 4X ?

Thanks !
