  1. My telescope is struggling pushing 180x magnification, I make out the details but they are blurry. At 90x my image is very clear and sharp, but I can't make out the red spot. The telescope appears to have a limit of about 160x. I'm about to buy a new eyepiece, and the best deal I can get right now is for a 128x. Will this be enough to make out details/red spot/moon shadows? Or should I try and find the ideal eyepiece that could push 150-160x to be safe? Thanks! Extra info: ED80 80mm f/7.5 with a 6.7mm Explore Scientific and a 2x Televue Barlow (this gives me 90x and 180x) Im looking at the ES 4.7, which would give me 128x
  2. Hey guys, I'm going on a fishing trip soon and will be bringing my telescope. I have an 80ED Apo, and the appropriate T-Adapter for my DSLR. What I'm wondering is if I should waste my night trying to take shots of nebulas/galaxies/clusters with my dslr, or if I should just enjoy the views. Basically the telescope is 600mm, f/7.5. I can only imagine that my exposure time would be limited to 1 - 1.5 seconds. I dont have a tracking mount and would need to manually track the target (I'm guessing registax would take care of aligning the target afterwards). Can I get anything worthwhile from this? or should I just mount my camera on a separate tripod and let it take wide angle long exposure time lapse. Cheers!
  3. I am aware of this, but I am not delving in DSO photography yet. This mount is basically just to keep me busy and to slowly get all the gear I need. Eventually Ill be willing to dish out 1500$+ on the mount, but even if I did so now, I wouldn't get a chance to use it. I live in the city and I just need a decent portable setup, and EQ mount and its counter weights would be way too much to lug around, and I think it would end up just picking up dust in my apartment
  4. I did get a good diagonal , I don't think that the focuser being at an angle would change the views. I just think that it would be more comfortable to use if I dont have to reach for the focuser under the telescope, and instead have it on the side like it was meant to be. Yep! I got the dovetail ready and mounted on it atm while waiting for a decent mount to attach it to. If it would allow me to save money, I think I would go ahead and unscrew it, but its a little intimidating. I think I'll give it a try though once I get the mount, if I find the angle annoying. Thanks!
  5. Hey guys, Im about to order a mount for my Orion ED80, and realized that this will end up putting my focusers vertical instead of horizontal. http://www.company7.com/orion/graphics/Orion80mmED697200.jpg http://www.astromart.com/images/classifieds/576000-576999/576960-2.jpg This is my first time with a refractor, so I'm not sure how things like this are managed. I'm wondering if I should be unscrewing these screws and rotating the entire thing : http://imgur.com/8UQQHvK Im wondering if this will ruin the collimation or if its a bad idea in general. How would I go about dealing with this? Cheers!
  6. Thanks everyone, after searching for a couple of days, I decided to go with the Vixen Porta 2 with carry case, as it seemed like the lightest option, and easiest to carry http://ecx.images-amazon.com/images/I/61fNnuUQW2L._SY355_.jpg http://www.vixenoptics.com/acc/carrycase2%20copy.jpg
  7. Thanks for the reply! This does look like a really good bang for buck mount, and will keep it as an option for now. My only issue with it is that its 16lbs and still reasonably chunky. I may come to realize that thats the best option, but id like to see if there could be anything lighter/more portable
  8. I recently bought an 80mm apo refractor for its portability and ability to take decent planetary pictures. I'm looking for a portable mount that could hopefully fit in a backpack (its ok if it sticks out). The 80mm refractor only weighs ~5lbs, with my dslr on it along with barlow I dont think it ever goes over 8lbs. I currently have 2 camera tripods that I can mount this setup on, but it is waaaaaay too wobbly, especially when wanting to adjust the view. Ive noticed some tripods have these long rotatable handles to guide the telescope around, I would really like that because I think it would probably make the views a lot more stable when scanning the skies. http://imgur.com/a/hOwHt Is there an option for me? I know I cant get an EQ6 kind of stability if I want portability, but I'm trying to find the best compromise. The refractor is very light, and I feel like there must be something out there thats reasonably portable that could do that job. Thanks!
  9. I am going back tonight to see if they can fix it up for me, I will report back!
  10. Hey Jonk! I currently have a 600mm f/7.5 tube. I figured that adding a 2x barlow (or higher?) could get me close enough to get half decent shots. Also, for the sake of saving money, would recording from my DSLR work the same way?
  11. Hey guys, I was interested in astrophotography, but I found that I didn't want to invest in a huge EQ mount just yet. I got myself an 80mm Apo, and everything needed to attach my dslr to it. I have managed to take some very nice pictures of the moon, but with jupiter looking so good and saturn coming up soon, I was hoping I could take some nice shots. I am on a non motorized mount (for the time being) and can only take single short exposure shots. Naturally between these shots, jupiter will travel across the view. I'm wondering if theres a program that could let me grab say, 20 dslr shots (of constantly realligning the planet in the center of the view with slight offsets in all the shots), and stack them. I heard this was possible with filming, but I would much rather have the 24mp resolution of my pictures. Which program should I use and can this be done? Thanks!
  12. I just bought my first refractor, 80ED Apo, and this is what the lens looks like: http://imgur.com/a/Kfj2G I tried dusting off from the front, and from the inside of the tube, but it doesnt seem to leave. These images make it seem a little worse than it looks like irl, and I can't see these specs at all when viewing through the scope. I've no doubt in my mind that this is not ok, but this was the last model where I bought it and I know that if I bring it back I might get a refund if I make a big deal out of it, but I wont be able to find the scope locally anymore. This was a brand new box, everything else apart from the lens seems perfectly fine. I'm wondering if this is just normal dust inside the cap that I could clean with some type of long swiffer (with appropriate cloth) or if I should just return it. Is this something normal that happens to refractors when left aside for a while? Thanks!
  13. Thanks for the reply! The ES really does seem like the better "long term" telescope, I doubt I will feel like upgrading for quite some time if I get that one... I know the feeling of regret thinking I could have just dished out a bit more money to get something more worth while. Let's say I go with the ES, its listed weight says 7.5lbs. I dont know what setup you have it on, but would you, or anyone else know if the 7.5lbs telescope + dslr equipment would be too heavy for the Celestron NexStar 6ES mount? The mount says it has a 12lbs limit, but I'm finding it hard to gauge how heavy the whole DSLR setup will be, and if I might get some wobble... In which case the Orion at 5lbs might be the better bet...
  14. This ^ I understand EQ mounts are best, but given my current situation (living in an apartment building downtown) the EQ mount would just end up picking dust and I wouldnt want to lug it around. I plan on getting an EQ mount somewhere down the line, but for now I know what to expect of an Alt/Az and I know its limitations. These pictures are, in my opinion, more than satisfactory for beginning astrophotography.
  15. I'm looking for a decent alt/az goto mount to use with an ED80 Apo (weighing 5-8lbs, depending on which one I buy). I've been searching a lot for one of these mounts sold seperately, but as it stands it seems like I have no choice but to buy in a bundle. Considering that my tube +dslr will probably end up at ~10lbs, Im wondering if anyone would have any suggestions. This will be for short exposure astrophotography and I know that an EQ mount would be better, but I live in the city and I might not benefit much from long exposure anyways, and the entire setting up hassle. It seems right now that my cheapest option is to buy a Nexstar SE4 and to just keep the mount. I can't find any details about this mount, and I'm not even sure if it can handle the 10lb load.. Are there other affordable options for me? Maybe the SLT mounts? Cheers!
  16. Thanks for the reply! Given that you own both cheap and expensive ED80's, would you mind telling me what the small perceivable quality would be? Does it relate with the chromatic abbarition, the amount of focus across the field of view, the light gathering ability (do you see more details in the more expensive one?). Cheers!
  17. This thread needs to keep on living! I'm going to be buying my first Astrophotography setup soon and I really dont want to lug around a huge EQ6 wiht the weights. Im looking at an Orion ED80 or Explore Scientific ED80 and these posts are helping me consider which mount would be best for a grab and go setup!
  18. I'm looking to purchase my first astrophotography setup, and I'm conflicted about these 2 refractors. Currently I can get the Orion at 499$, and the Explore Scientific at 749$. These scopes both have amazing reviews all around, and I know the Explore Scientific probably makes better optics than Orion. My quesiton is, are the better optics of the ES significant enough for me to notice? Or would a beginner like me be fine with the Orion. I know I will be keeping this scope for a long time, so if I have to dish the extra 250$ for something I know will be significantly bettery, I will, but I'm just wondering if it is. Thank you!
  19. Hey that actually worked! Ive used stellarium to measure normal eyepiece and telescope FoV but didnt know it had a camera option. Thanks! This leaves my last question. Does using a 1.25'' adapter on a 2'' telescope reduce the light by .75''? Cheers!
  20. Edit: Also related to this purchase... All of my equipment is 1.25'', and the description of the telescope says it accepts both. Will I lose light by using a 1.25'', or will it make no difference?
  21. Hey guys, I'm considering getting myself an Orion ED80 f/7.5 to begin astrophotography. I've never connected my DSLR on a telescope before, and Im wondering how the magnification is calculated. If I were to get the proper equipment to connect the DSLR to the telescope, as I understand it, there would be no eye piece to magnify. I have a TeleVue 2x 1.25'' barlow and I heard its possible to use a barlow with a dslr, but I'm wondering if it might be enough to get decent pictures of Saturn/Jupiter. How can I know the magnification I will get? Thanks!
  22. Hey dph1nm, Im slowly leaning towards the Nexstar Evolution (which should have a better mount), but im wondering if 6'' would be enough. From the thread that was linked it seems that the Nexstar 102SLT gave the most bang for buck (I can get that scope here for ~550$). I like the Evolution because it's a hassleless all in one package with an on board battery, and reasonably easy to move around. What I'm wondering is how the Nexstar 102SLT was able to get such amazing light gathering, I thought that it was designed for planet viewing not deep sky objects... As it stands now I'm wondering if just getting a 102SLT might be simpler and more affordable, or if I should get a 6'' Evolution, or an 8'' Evolution.
  23. wow that is a great thread! I wish there were more like it, I cant believe these were taken without an EQ mount... I live in light polluted skies, and getting an EQ mount might be good for one I leave town, but if these guys were able to get pictures like that on a non EQ mount, I think I'm sold... I wont be taking AP as seriously as most, if I can get shots that resmple the ones in that thread with such modest setups, I will be more than happy.
  24. haha yea there would probably not be any advantage for either of us to do that thanks for all the information though, I'm a long way from buying anything just yet, I want to learn more and keep shopping around, and all the info you gave me was very helpful! Cheers!
  25. That image is really more than enough quality for me! That's a beautiful shot. I'm in an artistic field so I have had my fair share of playing around with processing images, although I know it will be different for AP, I am more than willing to get good at it. Im wondering if there is any advantage in being able to take a 60 second exposure picture, vs 2x 30 seconds stacked. If there is not that much of a difference I think that going for Alt/Az with some dedicated post-processing might be best for me.
