  1. I recently acquired an ASI 178MM (non cooled) and seem to have a bit of a problem. I have managed to get it connected, but often, it will simply not download frames. It just sits there. I have an ASI1600Cool and that works first time, every time, but this 178MM is far more precocious. Just as I am about to pack it up and send back, it comes to life and behaves perfectly normally with fast framerates etc . I have swapped USB3 cables and same result, reinstalled all the drivers, same result. I think I just want confirmation that I am not missing something daft and that I should send it back for appraisal by a professional!
  2. You are pretty much there. If you are confident that your newt setup has no focus difference between filters, then you can always do L,L,R,G,B,L,L,R,G,B... or something along those lines and dither every cycle or something like that. That way you can be sure to have something by the end, as opposed to the soul destroying L, R, G and no Blue for 2 weeks because of the weather
  3. That camera will make a decent planetary imaging setup with your scope, but I wouldn't think too hard about doing DSOs with it. It can be utilized as a very decent guiding camera once you make the move to DSOs, but you should get a lot of joy and fun out of that camera with your Mak for planetary, lunar etc.
  4. The star core holes are usually as a result of HDRMultscaleTransform operations. A simple star mask to protect bright star cores is the solution for this one...
  5. There always seems to be a little play in the place where a Canon fit locks into the T-Adaptor for the DSLR. For imaging, it has the potential to move as the imaging train tracks, and also move if the scope/lens gets buffeted by wind. You can get away with it most of the time though I have found. Baader do a decent T-ring which seems to be tighter than cheaper alternatives, but still the movement is there if you wiggle the lens. Using it for guiding may make it worse, but that completely depends on the various image scales of the guiding versus main imaging setups. I have added tape on both sides before, once locked in, to try and add some resistance to movement to my system when using a setup like this.
  6. Its like one of these : http://www.rothervalleyoptics.co.uk/baader-v-dovetail-clamp-70mm.html
  7. If the light beams enter the scopes perfectly parallel to the pointing of the scopes, then I would have thought that it makes no difference if that system is one single scope, or multiple smaller scopes all perfectly parallel with one another. Light from stars arrives in parallel beams, so unless we are talking about extreme widefield, where projection of the curvature of the celestial sphere comes into play, I would have thought they are completely interchangeable.
  8. The holes in the stars are processing artifacts from the stacking. You need to have a play about with the stacking/processing parameters to avoid getting those. Welcome to the wonderful world of data processing...
  9. I used the one from ModernAstronomy: http://www.modernastronomy.com/shop/accessories/polemaster-adapter-for-star-adventurer/
  10. I have a polemaster, so PA is pretty good after doing that. Also, with short exposures, it doesn't really matter if it drifts slowly, natural dither,albeit during subs as well
  11. The first 2 images are with the TS60, the second 2 are a 50mm prime lens. As for guiding, I don't bother. The Andromeda image for example. Taken from Kelling, a campsite in East England. 360 x 30 second exposures for Luminance. 90 x 10 second exposures for each RGB. That is all that is needed. Unguided can achieve that, as you don't need long subs on bright targets, especially with a fast system and a sensitive CMOS camera.
  12. Thanks. The tripod is a bit of an extravagance, but I really liked it, having struggled with a cheap and cheerful eBay special before getting it. https://www.berlebach.de/?bereich=details&id=249&sprache=english
  13. https://www.teleskop-express.de/shop/product_info.php/info/p7275_TS-Optics-Photoline-60mm-f-5-5-FPL53-Apo---2--R-P-Focuser.html I also have the reducer, so it comes down to 260mm FL at F4.3 which is pretty quick and useful for the short exposure times I use with the ASI1600.
  14. Missed this thread till now. Shame on me. Some awesome work being done with this little mount. I have not had my SA out for a while after a house move, but here are some of the images managed over the last 18 months with it, all unguided with both scope setup and a Canon 450d/50mm lens. Also showing off the mono rig on a Berlebach tripod to keep the whole thing low and out of the wind.
  15. I also have the full SA setup and have managed to use it successfully with a DSLR and various lenses and also a full mono imaging setup with a TS60 scope, motorfocuser, full SX filter wheel and an ASI1600. If you have a fast imaging system, then you can ignore guiding, like I have done and never tried. I did 2 mins with a DSLR and a 50mm lens and 30 second exposures with the imaging rig, at 260mm FL. I attached a polemaster connector to the dovetail bar, as I already had a polemaster and using this for PA is much easier than contorting to look through the polarscope. A decent tripod is a must though, as this will kind of make up for the crude wedge, which is the wobbliest bit of my setup.
  16. No matter what I do, things look messy, but this now all works. Altair Astro Wave 115. Trusty ST80. ZWO cameras, ASI120 and ASI1600. Just the one power cable to plug in when setting up. Anything for an easy life...
  17. After much fussing about with this rig, I finally managed a full image. The faffing has involved flatteners, PCs, WiFi struggles, backlash and of course all the usual elements of astrophotography. I think I have got things working though, and now it is all set up, there is little, other than clouds to prevent this setup working well for me. AA115, AzEQ6, ZWO ASI1600, ZWO Filter wheel. using an Eagle2PC. Guided with ST80/ASI120. Carolines Rose. One of my all time favourite DSOs, both for visual and imaging, can't get enough of it. 25 x 2 mins for each RGB.
  18. well well : https://www.ioptron.com/product-p/7300.htm
  19. That is a quite wonderful visual setup, I hope it serves you well. Great to see a Panther in action, intriguing mount.
  20. PrimaLuce rock. They knew what the password was and replied to me on a Sunday, in time for some playtime tonight under the Moon. They even had a sense of humour about my stupidity. Can't ask for more than that, legends.
  21. Thanks. Wish I had read this before I threw away the box
  22. Cheers. My interweb search-fu needs some work it seems ?
  23. Thanks - The default wifi password is the first hurdle ?. I imagine everythjng else is pretty straightforward. Yes, the Eagle2 one.
  24. I did this course a couple of years ago and thought it was absolutely brilliant. It is now back and enrolling if anyone else might be interested. I still watch the videos on occasion. Duke University's Introduction to Astronomy course taught by Professor Ronen Plesser http://duke.is/su9c13
  25. Anyone got a pdf of the Pimaluce Eagle manual? Am setting up my new one this weekend and either did not get a manual, or have misplaced it. Waiting until Monday to play with my new toy is killing me :). Cheers Matt
