    • That looks like the “Venetian Blind” effect that is/was a feature of the sensor used in the Lodestar. The Lodestar uses an interlaced readout CCD, designed for video cameras, each image frame is read twice, the even numbered rows sequentially first and the odd numbered rows sequentially after. The acquisition software has to be able to reassemble the two frames in the right order otherwise it splits the frame vertically as though looking through a Venetian blind, one row has image data that captures a star but the next row down is blank and that makes it appear as though you have multiple stars closely split. I’m afraid I have no experience of using PHD for guiding with a Lodestar but when using MaxIm DL there was a bunch of configuration options in the camera setup amongst which were “Swap odd and even rows” and “Remove Venetian Blind effect”, which used together assembles the image odd/even rows in the correct order and corrects for any brightness variation between the two rows due to the timing difference when reading all the even rows first and then going back to read the odd rows in a camera that has no shutter and continues to collect photons in the odd rows even while the even rows are being read out. In PHD look for a camera configuration setting that might be called “de-interlace”, or similar, as that will be needed when reading out an interlaced CCD camera. You won’t find that in the ASCOM driver, and not in the hardware driver, it is something that the processing software needs to resolve and if it can’t then bin2 is the only option that will automatically remove the “Venetian Blind” effect and produce single stars and not what appear to be multiple adjacent stars. Sorry I couldn’t give you a PHD specific solution. William.
    • The SkySafari integration works very well so you get the best of both worlds 👍

    • Heya folks, it has been an interesting read catching up with this thread since ordering, receiving, and having had chance to spend about a month with the S50! I hope you don't mind me shifting direction of the thread with a brief observing report from tonight. Was thrilled to have some clear skies, and have chance to take some images to share with loved ones.  So, I'll start with the best image of the evening! M51. I have a little postage stamp of a garden, that faces roughly NNE. Weather report seemed to show that trying to get out into the wild tonight would have been touch and go, so this and all the rest come from my Bortle 4 garden. M51 shows 53 minutes of data in the time stamp. This took about 2 hours to collect in reality, with some high level cloud and star trailing issues confounding the S50 stacking more. I have the raw frames for the whole evening though, and look forward to learning how to process them Next best image of the evening was M97. There are some star trailing artefacts on this image, but once again its just the live stack from the S50. Targets were few and far between in the garden tonight, and almost all of then at or close to zenith. Obviously a challenge for any device only moving in 2 axis in a fixed alt az set up.  I already had 1 hour of data on M81, but some forum trawling  showed me I had missed a trick, and could have got M82 into the frame as well. Well, I've had a week of rain to ruminate on my failing there! Alas, both objects soon eluded the gaze of the scope, flanked, as they are, by the neighbours houses! I have to say, as short on data as it is, and how bad the framing may be, I love the composition of this shot. And now, moving progressively from bad to awful, may I introduce you to my attempt at M108. I'd hoped to be able to get enough of this for a friend, who is a keen surfer, to make a birthday card. Even with cropping, I don't think I'll get something satisfactory! The field rotation is pretty impressive for how truncated the data collection was - but at least I caught some photons Finally, a very tiny set of 6 x 10 second subs on M94. This was enough to notice the streetlight next to it ruining the attempt!  All told, 6 of the Messier objects on an evening where the forecast made me sure it wasn't worth going out. I completely understand that the S50 isn't a device that will please everyone (and indeed, does such a thing exist?). To offer an analogy, however: I enjoy balancing the carbs on my VFR400. And my enjoyment of doing so is in no way diminished by the fact that others enjoy riding fuel injected bikes. Clear skies all, Ryan
    • Hello and welcome to SGL I am still a newbie here myself but there are a lot of friendly knowledgeable people on here and I am sure someone with more info than I can offer will be along soon. I would say though have you had a look on FLO's website for WI-FI capable kit so you don't need to run cables outside?

      Hi, zakalwe .  How about the  proms with Lunt 60 and The DS 50 etalon? Assume they look better with single etalon?  Thanks.    Miertje.

      The sky has ben briefly clear for a change so captured some data. A spectrum from the carbon star La Superba and some video clips of the Full Moon. The Lunar data gave me the opportunity to try James Ritson's latest lunar disc macro for AFFP02 which was in his last update. Excellent for high definition, even when using my mini rig and 66mm Altair Lightwave scope. Have put image of Full Moon in my Moon Album. Still working on processing the spectrum.🧐
