  1. Based on my experiences between Morpheus 6.5mm and BST 5mm, I'd say the former offers more eye-relief, much wider fov, darker backgrounds and most importantly no ghosting on bright targets such as Mars and Jupiter. I also had the 12mm before I sold all my BSTs. It was the best of the bunch. If the Morpheus 12.5mm performed similarly to the 6.5mm, the only benefits I could see would be eye-relief and wider fov. Whether these are worth the extra cost is up to you.
  2. The Stellarlyra Dobs are made by GSO, so if you search up GSO dobs (e.g. GSD 200C), you should be able to find some info on them. AFAIK the optics are about the same between GSO and SW dobs, but the mechanically the GSO is slightly more superior. You could also have a look at the Bresser Dobs. They are pretty decent.
  3. I've got the essential laser collimator from FLO along with a collimation cap for my 200P. I used the cap to center the secondary through the focuser, then the laser to aim the secondary at the centre of the primary and finally align the primary. The laser collimator arrived slightly out of collimation itself so I had to use the method found on youtube to collimate that first.
  4. Have a look at: https://tftcentral.co.uk https://www.rtings.com/ https://pcmonitors.info then make up your own mind. For photo editing, the key parameters are colour space coverage and colour accuracy. For very serious work, look for one that has hardware LUT and get a colorimeter to go with it.
  5. These imaging oriented fracs require extension tubes to reach focus without a diagonal. Your ES70s afaik are pretty much the same as many other 70 afov eyepieces based on the 5-element Erfle design. (e.g. WO SWAN). These kind of eyepieces aren't going to give you the best views with scopes faster than f/6. If you're on a tight budget and ok to sacrifice a bit of fov, BST starguiders are worth a look. They are supposed to be good down to f/5. More expensive options include ES68, ES82, Baader Morpheus and APM UFF (Altair also sell the same range under their own name). Or for top of the line ES92/100, Televue, Pentax XW or Nikon NAV.
  6. You need to make sure you've got CIFS client 1.0 support installed in the Windows features. Win10 by default has CIFS 1.0 support disabled.
  7. Agreed with what have been said above. Also have you tried with straight-thru view? This is just to eliminate the diagonal from the optical path in case it's broken. And f/5.5 is pretty fast, probably too fast for your ES70 eyepieces. Jupiter isn't at its best altitude yet, but with sufficient cooldown and observing near the meridian under above average seeing there shouldn't be any visible CA in a well collimated triplet. That's what I saw with my APM 107 last week which is also a sharpstar scope.
  8. The 130PDS is a very capable scope once you've got over all the hurdles of imaging with a newt. Unless you want something that can't be done with the 130PDS (e.g. very wide field imaging, or portable visual setup), I'd say stick to what you've got and save the money.
  9. Might well be a defective UPB. Maybe return it and exchange for a PPBA if you have no use of the stepper motor or 20A.
  10. I could be wrong, but I think the embedded stepper motor is conflicting with the mount when you have your EQ6-R connected via the UPB. This configuration means two FTDI chips are trying to negotiate their own COM ports via the same physical USB port on the UPB. This might not be technically possible. If you can have everything else bar the mount connected via the UPB, I wouldn't think that as "cable hell".
  11. Have you tried connecting the mount directly to the PC? If you aren't using an EQDIR cable, your EQ6-R must be a later model with the built-in USB port (my AZ-EQ6 also has this port, but I still stick to the EQDIR cable). That USB port has a FTDI chip embedded. Maybe this has problem going through the USB hub on the UPB.
  12. I believe that Prolific USB COM port is installed by the embedded stepper motor in the UPB. Since our PPBA doesn't have that feature, we would only see the COM port from the FTDI chip in the EQDIR cable.
  13. +1 for TSA120. It's also the one most likely in stock if you want one urgently. TOA130 is out of your price range. APM-LZOS 130 f/9.2, TEC 140FL, CFF 135 and 140 are all out of your range plus there is substantial amount of waiting time for all of them.
  14. Try one step at a time. First see if NINA can connect to the UPB before physically plug in your camera and mount. Follow this with the camera and finally the mount. Also try different USB ports on your PC. Is the mount plugged into the PC directly or via the USB hub on the UPB?
  15. Does the Pegasus own software see your UPB? Check the device manager to make sure you're connecting to the correct COM port. I've only used my PPBA alongside EQMOD once with NINA before switching to Ekos/INDI. I didn't recall any connection issues.
  16. My bad. Apparently SW already includes this filter drawer/adaptor with the .77x reducer. It sits between the actual reducer optics and the M71 to M48 spacer.
  17. My first reaction when I saw this was that it was produced by a stock DSLR. Most emission nebulae are Ha heavy, so to make the most out of your limited exposure time you will need to astro mod your 800D. When stacking always reject those subframes with irregular star shapes if you want perfect result. Keeping them in will only deteriorate the overall quality of your image. Do you dither while guiding? Dithering helps remove walking noise in the image. Also un-cooled DSLRs have higher read noise and dark current than TEC cooled astro cam, so the result is always going to be a bit more noisy. When processing make sure multiple curves are streched little at a time and don't oversharpen or else the end result may be grainy and contain banding.
  18. Only those designed with a 2" nosepiece for push-fit attachment (e.g. my TS Optics 2" 0.79x reducer). But the more common screw on type can't (e.g. my Riccardi 0.75x reducer).
  19. For mono you would be using a filter wheel mounted between the reducer and the camera (closer to the camera to minimise possible reflection). For osc a filter wheel is overkill, you could try one of these. https://www.firstlightoptics.com/zwo-accessories/zwo_fd_m42.html https://www.altairastro.com/altair-2-inch-magnetic-filter-holder---m48-front-t2-back---version-2-6478-p.asp They both accept standard 2" filters. The ZWO one from FLO is currently out of stock, so if you need one now, you will have to go with the Altair. You will need to rework your spacing factor in the filter drawer plus the roughly 0.5 - 0.7mm increase in spacing due to the filter slightly altering the light path.
  20. +1 for ES68 20mm. Very comfortable to use and well corrected views.
  21. I used to own 25, 12, 5 and 3.2 BSTs. The 12mm was definitely the best of the bunch, very crispy views. The others were fine eps also, better than stocks but not quite on par with the more expensive equivalents. I had the problem with ghosting on bright targets using the 5mm (very prominent when looking at Mars or Jupiter), not sure if it was just my particular sample. The 3.2 on your 130p newt will yield 203x mag which would be useful for the moon and planets only under very good seeing condition.
  22. Polar alignment is completely separate from everything else. I think you probably got it confused with the star alignment that helps the onboard computer to build the star map. When you switch on your mount, it already assumes the RA axis is pointing towards the NCP/SCP.
  23. Universal Flattener like this one https://www.firstlightoptics.com/reducersflatteners/hotech-sca-field-flattener.html, can be used with a wide range of refractors between f/5 and f/8 (sometimes even f/9). TS Optics and Sharpstar also make one. So you can combine it with any 70 - 80mm refractors you like. The main problem with this kind of setup is that you will have to work out the correct spacing between the flattener and the camera through trial and error yourself.
  24. TS Optics were also selling the rebadged 94EDPH. If you include those, the number of reviews will be more. But yes I wouldn't say there are *many* reviews.
  25. I've got the APM 107 which is a rebadged Sharpstar and is now discontinued. Overall the quality is very good, definitely up there with the best Chinese APOs. The only negative comments I've read so far are about the 61EDPH II on CN. The 76 and 94 have got good reviews. I haven't seen many user reports on their big 140 dual EDs. Which one are you thinking of buying?
