Re: Mount Status Not Updating in MaxIm DL Observatory Control Window

Roland Christen
 

At Ray's suggestion I plugged the mount into a USB socket on one side of the laptop and the camera into the opposite side (USB ports separated). That seemed to have fixed the issue. Normally I plug them in to the 2 adjacent USB ports, and that's where the trouble occurs.

I plan to get a new laptop now that I have hosed this one in the rainstorm. Any suggestions for a laptop that can process the ZWO 6200 full frame color images that are of enormous size? Right now the laptop cannot combine more than 4 of them before giving up the ghost. Not enough memory apparently.

I finally got to test my system outdoors last Friday night to see if I could duplicate the original problems that I experienced on November 8 when the mount status and position stopped communicating to MaxIm DL, locking everything up.

I had everything set up the same way as I did for my previous indoor test. I put the mount through several slews to different objects with no issues. At each object I started autoguiding with the guide camera while taking images through the main imaging camera. I took several autosave sequences as well as a number of individual images. Throughout the evening everything behaved normally.

I have run out of ideas for things to check, so for now I will just assume that it was some kind of anomaly.

Leo Galaxy Tour

Roland Christen
 

Hello Astronuts,

While visiting Hawaii in the spring of last year I had a few clear nights and did a galaxy tour in Leo. Here are some of the images. All were short exposures, snapshots if you will, and I was mainly concentrating in resolving the cores of these galaxies at the expense of the deeper field. Thus the short exposures of 300 to 600 seconds in order to prevent saturating the cores and blowing up the detail. I only had a few days that were suitable for imaging these cool galaxies. All were taken with the 175 EDF on the 1600 Encoder mount, unguided.

They are in my staging area, I'm too embarrassed to show them to the rest of the Astrobin crowd Grin

Excellent, thank you so much, Ray!


Re: On AP Telescopes

Biggest standard refractor was a 10" Triplet.
Biggest refracting system we made was the 12" Honders which used 2 refracting lenses of 12" aperture along with a folding mirror and a 3rd element of 4" aperture near the focus. This telescope is a variation of the Schupmann Brachymedial that dates back to the 1890's.

I seem to recall seeing a post on the forum where Roland said that it was really hard to get suitable glass for the larger lens sizes. Is that still the case Roland ? I remember that Astro-Physics sold a limited number of 205 mm refractors. What is the biggest refractor lens you ever made ?

Hi Patrick,

Because there is an update to the Eltima drivers, you should uninstall 1.8.8.17 first, then install 1.9.x. You will not lose any settings.

It was mostly an idle thought, but I wish I’d been paying more attention when you were producing the 175 f/8 StarFire EDF back in 2012.

Hi Howard

Yes, I really count myself lucky to have a 180EDT. It is a great scope.

Before I bought the 180EDT I had been debating between a Celestron C14 and a 7-inch F9 Starfire. About the same time that I decided to go with a refractor, A-P introduced the 155EDF with the 4-inch focuser. I really liked the 155EDF and the beautiful astro-photos taken through it that Tony and Daphne Hallas were publishing in the magazines. So, then I had a to decide between the 7-inch F9 Starfire, and the 155EDF. I decided to go with the 7-inch F9 because it had a larger aperture and was considerably cheaper than the 155EDF. I was ready to place an order for the 7-inch Starfire when I learned that A-P had sold out of the 7-inch version. I thought I was out of luck on a large refractor until I talked to Marj on the phone and she told me that they were phasing out the Starfires and going to start producing the new EDT design which would be available in a 180 mm aperture. Shortly after that phone call I placed my order. 

There was no notification list in those days, and I must have been one of the first people to order a 180EDT. The serial number on my lens cell is 18010.

Re: On AP Telescopes

Wow, a 180? That puts you among the Elect, for sure! I bought my 155EDF not long after that, and I can’t recall whether the 180 was by then unavailable or merely unaffordable. The 155 will be one of the OTAs that I’ll be using in rotation on the 1600GTO that’s to be delivered in February and which I’ll mount either on the Giant Field Tripod from my Meade 16” LX200 or on a pier.

Life is full of missed opportunities. When I ordered my first A-P scope back in 1992 I was mainly interested in the 180 EDT, but I was also going to order a Traveler along with it. Unfortunately, my budget could not quite handle two refractors and a mount all at once, so something had to go. I took the Traveler off my order intending to buy one later, but I never did.

Re: On AP Telescopes

My AP Traveler was a great astrograph with the field flattener. Supported 6x7 film format no problem, and when the SBIG ST10 came out, it produced wonderful hydrogen alpha images.    Unfortunately I never warmed up to it visually and eventually, like my domestic automobiles,  sold it for a Japanese import.  No regrets, but I am amused today as to how it has become a "must have" collectible with so many scopes in the same size and F/ratio range.  Out of my collection of AP telescopes, the 254mm Mak-cass is the clear winner when it comes to observing pleasure.  If I can keep only one AP, that would be it.  Well OK, maybe  keep the Stowaway as a finder for it.  ;-)

Re: On AP Telescopes

I notice Ed went back to the early, pre-ED Starfires, but no further back.  Too bad as the old 5" F6 was/is a complete blast.  Yeah it had some residual aberrations but a 4.5" to 4.0" stop knocked them down without too much of a hit in resolution.  And with the reducer, wow, was it ever a bright telephoto/astrograph (for film back then).  There was also the 4" F6 "Standard Christen Triplet",  "pre-Traveler" from back then too.  Again, with the reducer it was/is a dynomite telephoto, very sharp, color free and easy to handle.  One of the really dumb things I have done (and there have been many) was selling the best sample of that one I had.
