  1. Looks like your power tank may have "tanked" already. I have/had one and for a few months from new things seemed normal but very soon the status LEDs began to contradict each other, just as yours are . The indicators were meaningless. Then I discovered that the battery would not hold charge and anyway was not sufficient for more than a few hours running my AVX mount. Consigned it to the bottom of a cupboard just in case there is a short power cut... Replaced it with a much cheaper, greater capacity battery. Can't see exactly what you have and it may be the newer Li type in which case you may have more luck but already it is off to a bad start.
  2. LENR should not be used anyway as the result is not in RAW. RAW format (as unadulterated data as the camera can produce) is what you need for stacking. LENR corrupts the data even before you start stacking.
  3. Absolute final answer, yes turn it off. Waste of time with it on. And correct use darks and flats.
  4. Registax is usually a program used for stacking video (lucky frame) image capture, of thousands of individual frames commonly of the moon or planets. It is not intended for use in deep sky image capture and has no use in this so indeed we need to know what type of images and targets you are working from. If you are taking deep sky shots of nebulae and galaxies then programs such as DSS (Deep Sky Stacker free!) and StarTools or PI and many others are the way to go. These are two completely different astrophotography strategies requiring different techniques and equipment. If you can at least let us know what your equipment is in your profile or directly it would help.
  5. Absolutely wonderful ! So sharp I almost cut my eyeballs looking at it. Flying over the half moon frame was breath taking.
  6. Excellent! Much better. Looks like a good candidate for the No EQ DSO challenge now.
  7. I once needed to remove for the first time a dew shield with a felt band. Big strong guy as I am there was no way it would shift by hand. I tried a strap wrench. No dice. Wooden mallet? Yep that worked. After that the shield was as sloppy as something that is very sloppy and would fall off at the drop of a hat, (or dew shield.) I put a few crumples in the felt and it works fine now....
  8. Software testing was once part of my job, one of the most frustrating experiences of my career. After weeks or even months of testing a bug would show up requiring a fix in just one line of code. So I ask the S/W guy "So I only need to check the function of that piece of code?" "Yes, just that. Nothing else was changed" he declares. So I check it out. I notice there is a new dialog window in the GUI display. It concerned the operation of a 300mm butterfly valve with high vacuum on one side and full atmosphere on the other. Nothing to do with the original bug. The new dialog asks "Do you really want to open this valve?" Definitely NOT!!! I hit the NO tick box.... BOOM!! The valve opens ! Crikey! The whole factory shook as full atmosphere slammed into several cubic meters of vacuum chamber. Heads turned with accusing looks. Honest guv, it wasn't me! A further full SW debug was required over the next few weeks....We found many more newly installed bugs. I realised that there is no such thing possible as fully bug free code no matter how long it is tested. Don't be afraid of AI ! Human I is far more dangerous....
  9. Dithering will help but that is a tough proposition with an ALT/AZ without some software which I don't think can connect easily to an I optron AZ goto via a laptop. Others will know if this is possible. I agree the noise looks like a typical result from a DSLR. Perhaps the high ISO of 3200 does not help. Try ISO 800. An ALT/AZ when operating near the meridian and the celestial equator is at it's optimal position to minimise field rotation. Fortunately Orion's Belt is perfectly positioned. If the ALT axis is at 90 degrees,( E_W) to the meridian (altitude swings due N-S in the rocker box) the need for large adjustments in ALT is reduced as the field rotates little as it passes across the meridian.
  10. Looks like a bad case of field rotation. This is an effect of using an ALT/AZ mount with long exposures. 3 minutes is far too long. The star Alnitak is kept central in the field by the goto tracking but you can see the field rotating around it. Typically most recommend not to go much above 15 sec exposures. I would use shorter exposures and more of them.
  11. Yes, I saw the string of the first of the series launched way back in summer 2019. Fascinated but appalled. Then I took some comfort from it realising that when the UFO nuts start reporting them (or anything else) that we can debunk them instantly. No need to call on Venus refracted by swamp gas. Hang on there!....Where are the nutter reports ? Aren't they looking up? Does this mean they now know a satellite from a FTL mother ship?
  12. Remember those wonderful toys we had as kids? "Kaleidoscopes" I think they were called. I'll just trade in my scopes for a couple of those and won't notice the difference as I turn them to the skies...
  13. I was a little embarrassed that I posted some of my images in my gallery for the first time and did not realise that they would ALL be posted sequentially and seen as individual posts. I thought they would all just go quietly into the gallery without anyone knowing! So sorry if it appeared I was hogging the forum. Oooops. I guess there is a setting that prevents this in future. I'll find it...
