  1. Thanks for the advice, I’ll investigate. Presume neither will invalidate the warranty?
  2. First try this evening with an Az GTi on Gitzo mount and Mak127. Quick and easy to set up and seemed to take the weight of kit (circa 5kg) in its stride. Tracked moon and Mars very accurately. Only criticism, there was a small but distinct judder every couple of seconds like the ticking of a clock as the unit tracked. Presume this is down to damping of the tripod (lightweight series 5) rather than the mount? Hoped it would track more smoothly. Thoughts?
  3. Finally had a gloriously clear night for some DSO viewing. Decided to dust off the 18” dob, OVNI-B night vision goggles and Televue 67mm convertor / 55mm combo, all rested recently due to the poor weather and, when ok, exciting planet action. Also the fIrst time trying a new filter wheel, which is cheap, built like a tank and not easy to use/rotate but does the job allowing a quick comparison between filters; a 642 Astronomik pro planet, 12nm Astronomik and 3.5nm Antlia. I really struggled with the latter last time out back in Autum thinking there was far too much scintillation. But in hindsig
  4. Background: Very happy with my “grab” kit for lunar and planets (Mak127 on Gitzo). But the “go” bit is driving me nuts. Three times this week I’ve put the scope outside to cool under what appear to be clear and still skies only to check 10mins later and be met with cloud and rain. So I really need something that doesn’t require any cool down or collimation and is good to go pretty much straight away inbetween breaks in the cloud. I currently get great high mag views through the mak or big dob with a Binotron, 24mm pans and powerswitch on medium and high settings (circa x150 and x190 I bel
  5. Appreciate there are a number of similar threads but struggling to find a consensus on a reliable and lightweight, portable power option for the AZ GTI mount (mine arriving next week). Have narrowed this down to; a) Panasonic eneloop pro rechargeable AA batteries (or similar) but one or two comments suggesting these may not provide consistent/adequate power all the time for tracking and Wi-fi beyond a few hours? b) TalentCell Rechargeable 36W 12V/6000mAh 5V/12000mAh or the smaller/cheaper 3000mAh version (are these safe to keep in the house / not prone to get damaged or combust if le
  6. Some absolute crackers here in Edinburgh. Managed 20 minutes viewing with the family in the backyard seeing around 10 in that time. One in particular I genuinely thought was a firework someone had let off with an ultra bright head and very long tail. Incredible. Just about made up for the appalling weather we’ve had here since end September.
  7. Finally had a chance to try out a pair of Denkmeier D14s in a Mak127 and Binotron binoviewer. Very happy with my current 32mm plossls and 24mm panoptics but always hankered after something with more magnification. Targets were the moon and Mars. All I can say is wow the D14s were fantastic. Lunar views were noticeably brighter on all three power settings compared to the other eyepieces (was not expecting that). I was also anticipating high power to be a little washed out, as can be the case in the panoptics but they were actually the highlight of the evening. Apollo-like views. Eye pos
  8. I feared you might say that about the Feathertouch. Which model FTF did you go for?
  9. Anyone had any success using these together (obviously not all three at the same time!)? Having experienced the joys of true grab and go with a Mak127 the other night I’m looking for something equally portable for night vision (a 4” refractor) but also something offering wide field views with a binoviewer. If I’m reading the various posts on SGL correctly, the DC needs an adapter for the focuser to accept 2” kit, e.g. 55mm plossl for afocal viewing with an OVNI-B or the 2” Binotron. Appreciate upgrading the focuser is an option - but prefer that to come down the line. I’ve always u
  10. Interesting, I had to fit a Mak to Sct adapter to use my existing 2”diagonal which attaches to the Binotron. Challenge I have is the Binotron only takes 1.25” eyepieces. No fear though as the 32mm plossl’s used last night were great. Just need to work out if I get the Televue extender eyeguards or something similar with wings (I have some flexible rubber wings on my NV goggles and they completely block out all surrounding light like suction pads or a divers mask and they totally transform the viewing experience in my mind as you don’t notice the small FOV as everything is black!).
  11. Fingers crossed for you, am sure you won’t be disappointed. While you’re waiting I can recommend getting a finder scope as the red dot one supplied as standard isn’t great and with the scope having a small FOV it can be a bit tricky to centre items. I just need to decide now whether to get a 9x50 or 6x30. The latter appeals to help keep the weight down with a wider FOV but not sure if that then means it’s more difficult to spot your target? Also, regarding the 32mm plossl, does anyone know if these would fit? https://www.televue.com/engine/TV3b_page.asp?id=158 I bought a pair a
  12. 3rd night out with the new grab and go kit (Mak127 left outside to cool 1 hour, Binotron and 24mm panoptics). Four targets this time, something not previously possible in the backyard as surrounded by other buildings. Saturn - wow, best views ever. Crisp and clear on both low and medium power settings. Have previously viewed through a large dob and looked like a very small white ball with ears! But this was on a different level. No atmospheric wobble, ultra bright, with nice magnification. Jupiter - quite disappointing. Could just about make out some of the bands, no subtle red spot,
  13. Some great responses here (but a lot to take in!). Looks like different scopes depending on viewing objectives. a) Have big dob in back garden for DSO with/without NV goggles (and great with binoviewer for lunar and planets when in view) b) Have Mak127 for grab and go for lunar and planets (but not NV). Great views but small FOV so may have to add some fine tuning knobs or tracking (not fun nudging around). c) Perhaps a lightweight refractor for grab and go NV. I’ve seen a lightweight apo (4kg) in the 102mm F7 range. Is that the wrong speed for NV even if I’m using the 67mm Te
  14. For sale, a PVS-7 (OVNI-B) with very high spec HARDERdigital thin-film FOM2100 white phosphor tube. Purchased new from OVNI-nightvision.com in France a couple of months ago, spec’d specifically for astronomy and used just a handful of times. Absolutely stunning two eyed views both handheld and in scopes from my very light polluted backyard. Being sold to fund further NV purchases (I’m that hooked, as you will have seen from my posts on SGL). Comes with 1.25” barrel, c-mount and various adapters for both prime and afocal use. Bought new for Eur6799 (£6150). Being sold here for ci
  15. Thanks Peter, slightly off topic but I did consider a frac for a grab and go purely for lunar and planets (not thinking about the NV) but was put off assuming I wouldn’t get enough magnification due to the short focal lengths. I tried an ED72 for a while a few years ago which had a very wide field of view but I could never get close up to the moon/Jupiter having been used to doing that in an 8” F5 reflector. Even with 8mm “planetary” eyepieces in the binoviewer and high power on the powerswitch the views were small. I know I could go mono with barlows etc but I’m wedded to using both eyes. Not
  16. Living North of the border I often get text alerts about pending potential views of the Northern lights in the central belt but realistically will never see anything due to light pollution. Not sure if this would be possible through NV with an appropriate filter?
  17. Recently picked up a used Skywatcher Mak127 as a grab and go scope for lunar and planets (so far so good although the small FOV is a little frustrating and, being a reflector man am not used to the new viewing position even when seated - will try rotating the diagonal next time so I can view with a straight back/neck to make it more dob-like..). Anyway, will this be any good for afocal viewing with my OVNI-B NV goggles? Thought I’d read somewhere that NV works better with fast scopes (the Mak is very slow) but I may have just made that up. Loving the NV views through the big dob but portabl
  18. Round 2 last night. Decided to give my new grab and go set up (a skywatcher mak127) a shot at the moon and Mars inbetween breaks in the cloud. Binotron and panoptics in place. Initial views good although nothing special. Let the scope cool after an hour and wow, Mars was crystal clear. Not sure if this was viewing conditions or the scope but so much more detail on show and a clear disk with sharp edges. Keen to try more magnification but didn’t have chance to test. Then turned to the moon. Nice views on all 3 powerswitch levels, although difficult to make out detail as nearly 3/4 full. However
  19. Do I need an adapter to use a 2” diagonal (needed for denk binoviewers) in a skywatcher mak127? I’ve read a few threads about a mak to sct adapter but not sure how this would work once attached to the 1.25” focuser. Photo below shows the telescope side of my set up (OCS45 needs to enter the focuser but not sure how). Think I may need these two items: https://www.firstlightoptics.com/adapters/astro-essentials-2-visual-back-eyepiece-holder-for-sct-telescopes.html https://www.firstlightoptics.com/adapters/lynxastro_makcas-sct_adptr.html
  20. Clearish skies this evening so decided to try a number of different eyepieces in my Binotron binoviewer with powerswitch and 18” dob. 2/5 - First up a pair of new Baader mk4 zooms. Couldn’t get comfortable with these. I must have a big nose as they just didn’t “fit”. FOV seemed smallest out of the group, found adjusting the various magnifications fiddly (would struggle on a really cold night with gloves on) plus long eye relief so felt like I was looking through a ships porthole. Unfortunately will be returning these. 3/5 - 32mm Televue plossl. Bought these a while ago for lunar view
  21. Not sure if the Tecnosky elle v2 is more for binoculars? Presume would need a few more parts for the mak137 to fit? Looks very nice though.
  22. Missed that one (scope tech). Not sure though if it could take encoders for the Nexus (have asked Serge).
  23. Spent a week or two trawling through various posts trying to help me decide on a new grab and go mount - all very confusing so have tried to capture key buying info (for me) in the table below. The Cost column is base cost only and doesn't take into account shipping, import fees etc (which I appreciate will be high for some of the options - fortunately that's not a key criteria). I have a Mak127 and will use with a Binotron, WO diagonal and 24mm Panoptics - reckon the payload here is around 7kg. I will be paring the mount with a Gitzo tripod (TBC) and the set up must be genuinely lightwei
