  1. Hi piff No, it won’t remember the alignment unless you use the Hibernate function found in the hand controller. Use that and all you need to do when restarting the scope is to confirm the time and date. Make sure you don’t move the telescope at all while in Hibernate. There really is no margin for that, at least to my experience. Here’s more info: https://www.celestron.com/blogs/knowledgebase/how-do-i-quickly-start-my-celestron-telescope-can-i-use-previous-alignment-information Clear Skies, Tomi
  2. Hi Victor! I recently bought the scope in question and have really been enjoying it so far. I use a 2 inch William Optics Diagonal + Baader Zoom and I have had no trouble reaching focus. However, for DSLR you will need an extension tube, I use a 50mm one and it works just fine. You might also need a longer dovetail to balance the scope properly for astrophotography. The Evostar is a very good grab and go scope to go with your Dobsonian and it definitely deserves my recommendation! The case is excellent, especially considering it is included with the scope. Clear Skies from Finland, Tomi
  3. Hi everybody! I recently purchased an Evostar 72ED to serve as my grab and go scope and now I’m looking for something to mount it on. The scope will be used for visual only with no need for tracking or GoTo. Lighter the setup, the better. Can you give me some recommendations? What mount do you use your 72ED with?
  4. Yes it does, but only barely. Both Jupiter and Saturn have a maximum altitude of ~6 degrees above horizon. I just came back from outside after viewing Saturn. I could see the rings but not any other detail, it is so low in the sky. The only star I was able to see with the naked eye was Vega, the sky is simply too bright...
  5. Thanks @Stu ! It really is a nice place to observe, especially during the dark autumn months when it’s not that cold. I’ve been pretty pleased with the C8, it seems to be the perfect telescope for me. It’s right at the sweet spot between light grasp and portability.
  6. Here’s my CPC 800 in action, ready for some lunar observing. The picture was taken at 00:25 so technically it was taken at night, but as you can see, there really isn’t such thing as night here in Finland during summer. However I upgraded the stock focuser yesterday and just had to get a “first light” with the new one. Very impressed after a glimpse of Jupiter! Clear Skies, Tomi
  7. Hi! Canon 10D is a very old model (2003) and it only supports Compact Flash memory cards. I bet you can get a lot newer Canon DSLRs for £100. Personally I’ve bought a used 500D and a 550D for €100 each here in Finland and I assume that you should be able to find them in the same price range in the UK as well. 1000D is also very good for beginners and usually quite cheap. Newer cameras have a lot less noise and are more likely to be compatible with modern astro-software. DSLRs can also be used for wide field shots of the Milky Way. Keep in mind that you’re going to need a T-adapter and an intervalometer as well! Clear Skies! Tomi
  8. Thanks for all the replies! I have to say that I’m quite impressed by the positive comments regarding the SW 72ED. For it’s price it seems to be very capable. As I said before, the scope will be mostly for visual. It seems that for imaging the z61 might be the way to go, but for my needs the ED72 would be sufficient. Now all I need to do is to find a good alt-az mount for it! BTW, that’s a stunning image @hennyvenom ! Clear skies, Tomi
  9. Hi everybody! As summer is finally beginning to reach Finland and it no longer gets dark at night, I’ve begun to look for a new grab and go telescope for next season. Previously I thought about getting a Maksutov, but due to the required cool down time and cold Finnish winters, I’ve decided to go with a small APO refractor. My current (and only) scope is a Celestron CPC 800, which is fantastic, but definitely not something you can put to your backpack and walk to the nearest park with. I already had my mind set on Sky-Watcher Evostar ED72 but then I came across with WO Zenithstar 61. I know WO has a higher build quality (and price...) and is more compact than the Evostar but how about the views? Has anyone used one of these for visual? I currently have a WO 2 inch diagonal and a Baader Hyperion Zoom eyepiece, do these short refractors cope well with Hyperions? Does the 11mm make an enormous difference? Am I better off with the ED72 after all? Any other alternatives? I will be doing some imaging with the scope later on (my astro club has a Star Adventurer that I will be borrowing) but 90% of the time it will be for visual only. I will also be getting a field flattener eventually, no matter which scope I choose. Clear skies! Tomi
  10. The Explorer 130 you mentioned does not have a very good mount (You would experience lots of vibrations with that combo). It is wiser to save for a little longer and get the Skyliner 150P, which has a very sturdy Dobsonian mount and good optics + larger aperture than the Explorer 130! Believe me, it will be worth it. ?
  11. I would also definitely recommend getting the Skyliner 200p as it’s probably the best value telescope you can get for the money. If you need something portable though, I’d advise you to get Skymax 102. I started out with one of these, and was very pleased with it. https://www.firstlightoptics.com/sky-watcher-az-pronto/sky-watcher-skymax-102-az-pronto.html A pair of good binoculars (e.g. 7x50 or 10x50) will help you along the way. Also consider downloading Stellarium on your computer. It’s a free sky map. ?
  12. Hi Peter! I think Gaj is correct, it is most likely due to the recent GPS epoch. This has affected Celestron telescopes as well. From now on you need to manually set the time and date. Check this thread on Cloudy Nights forum for more info: https://www.cloudynights.com/topic/656941-party-like-its-1999-gps-gets-wrong-date/#entry9284685 Clear skies, Tomi
  13. I live 61°N and during summertime I casually observe the Moon, planets and occasionally the sun as well. Some binary stars (such as Albireo) can be observed, but that’s about it. The planets have unfortunately been very low in the sky for a few years now. The image below is a good representation of the light conditions here in Finland during summer. The picture was taken on the 1st of July at 00:54. ?
  14. What eyepieces do you currently have? Getting a Barlow will not be any help before you can actually locate objects in the night sky. As I said before, you're better off saving your money! ?
  15. Hi! I'd advise you not to buy the 5x Barlow. It will increase the magnification of your telescope too much. I'm not sure if you're aware of this, but the main purpose of a telescope is to gather as much light as possible, not to deliver the highest possible magnification. The 32mm Plossl is a good low power eyepiece, so that is recommended. The Moon filter is probably not necessary, as @pregulla mentioned. To be honest, the telescope you have is not of very high quality. Despite this, there are many objects visible with it. Have you looked at the Moon? The rings of Saturn and the moons of Jupiter are visible with your telescope, just don't hold your expectations too high. Some nice double stars, such as Albireo, can also be seen. How well do you know the night sky? If you feel lost, try a free software called Stellarium. ? If I were you, I'd save the money, learn the night sky and buy a better telescope. My recommendation is Sky-Watcher Skyliner 150P, Skymax 102 or the Heritage 130 mentioned by @mark81. A good pair of binoculars will also help you a a lot along the way. Tomi
  16. Hej davhej och välkommen! ? I can easily relate to the Swedish observing conditions. Cold winters and summers filled with daylight bring some challenges to the hobby.
  17. I currently own only one telescope, Celestron CPC 800. I find a 8 inch SCT to be a great compromise. It has enough aperture to show a good amount of detail on deep sky objects and enough focal lenght for the planets. The mount is so sturdy that you can even lean on it while observing! ? For planetary and lunar imaging the CPC is a beast and despite the alt-az mount, I’ve been able to capture some DSOs with my Canon 60D. Tracking is fantastic and the Goto is always spot on. The scope is quite big and bulky, but it’s easy to carry and fits well in the car. I have a pair of binoculars that function as my grab and go instrument, in case I don’t want to be carrying the CPC around.
  18. Don’t go for the National Geographic. It’s not a very good quality instrument. I’d also recommend getting the Sky-Watcher Skyliner 150P. The views are a lot better and it’s much higher quality. ? If you’re on a very tight budget, buy a good pair of 10x50 binoculars instead. You will enjoy them a lot more than you would enjoy a cheap telescope with bad optics and terrible mount.
  19. Hi Rob! Nice progress you have there! The star trails might be a tracking issue. How accurate is your polar alignment? Do you use an intervalometer to avoid any shaking during imaging? I suggest you to use a little lower ISO for less noise in the image, personally I use ISO 1600 while imaging with a DSLR. This will also help with blown up images. Andromeda is actually much larger than what is visible from a single exposure. Stacking more images will bring out the fainter detail. The stretched stars near the edges are caused by coma. This is normal for Newtonian telescopes and can be fixed with a coma corrector. Cheers, Tomi
  20. The 6 inch model seems to be available in Europe now. The price is €399 at Astroshop, sounds like a superb deal to me! ? https://www.astroshop.eu/telescopes/ts-optics-cassegrain-telescope-c-154-1848-ota/p,60781
  21. Have you tried changing the power cable? I had severe issues with my Celestron CPC when I bought it, but it turned out all of them were caused by a faulty cable.
  22. Short answer: Yes, you can. Long answer: The hand controllers are not interchangeable straight away, the software inside needs to be changed before one can be used in place of the other. If you plug the hand controller to the telescope and then connect it to your laptop, you are able to switch the EQ software to AZ and vice versa. For the newer Nexstar + (the hc on the right in your image) this is done via Celestron Firmware Manager and for the older, regular Nexstar, it is done via HC update. https://www.nexstarsite.com/OddsNEnds/HCFirmwareUpgradeHowTo.htm Use this link to learn more about how to update the firmware. I hope this helps. ? Cheers, Tomi
  23. Here's a quick picture of my scope in the snow. The Moon looked great tonight! ?
  24. Hi Deb! I have purchased a soft case to protect my telescope and a hard case for all accessories. I often transport the scope in my car and always store it in the back seat, usually I even use the seat belt to secure it in its place. ? I recommend getting a case. It will help you to preserve your telescope in good condition! I haven’t had issues with collimation so far, although my scope is a Schmidt-Cassegrain, not a Newtonian.
  25. If you use the telescope with the build-in wedge, the problem could indeed be polar alignment. I would also make sure that the telescope+camera combination is properly balanced. ? I recall there is a good video on polar aligning Nexstar 4SE on YouTube, in case you have any issues with the process itself.
