  1. **CAUTION** Thanks guys but I need to add a word of caution... The azimuth adjustment screws on the HEQ5 already 'bite' near the top of the 'stop' on the tripod. 2mm of aluminium actually lifts them dangerously close to the top so even though this little device works really well I can't recommend that others try it. Will need to think about it a little more... BH
  2. I hear what you are saying Reddoss but I want to give the bag a good test so I can report back to you guys! And as you know, when you want to test the waterproofing of an item our weather is always ready to oblige! I've been checking the weather reports for my area all day and it said we might be in for a brief spell of rain somewhere around 3pm. It's now been raining solidly for three hours. Ho hum... twas ever thus!
  3. My scope is outside getting rained on! Tehehehe Taking a childish delight in this new cover. But it had better clear up later!
  4. Don't care where it's from it's still a great pic! Although, coming from the Mail I'm surprised the headline isn't, 'Hand of God says NO to intergalactic migrant stars!'
  5. Hi all I know this topic has been covered many times but I thought I would share a new discovery with you. After the latest spell of infuriating weather I decided to look again at buying a cover for my 12" Flextube. I looked at all the usual BBQ and garden furniture covers but nothing seemed quite right. I started to consider an expensive Telegizmo but this just seemed excessive. I then came across a British company called Bags 4 Everything. The name says it all but they also offer a bespoke service at pretty reasonable rates. I asked for a quote for a bag to cover my 12" flextube dob and was
  6. Just incredible. Didn't see this first time round so thanks for posting it Svenito
  7. Thank you Patrick You made my life richer RIP
  8. Thanks for all the replies Quite reassuring to know I'm not the only who who has struggled to bag this particular feature. The best view I ever had of Jupiter was from the centre of Edinburgh with an 8" Meade LX10. The amount of detail was staggering, right down to tiny little swirls in the clouds. I still wonder if I dreamed it! @John... Really impressed that you could see it with an 80mm scope. I often toy with the idea of trading in my big dob for a more manageabloe refractor but then Orion is coming round and I would miss all those beautiful clouds! I can see how people end up with two or
  9. Hi all Don't know about you guys but last night was just perfect here in the Borders. Jupiter was beautiful and the seeing was pretty damn good. I saw the Great Red Spot properly for the first time in my life and I've been observing for years! This was the second best view of Jupiter I've ever had and it was a real thrill to see something clearly that I had only ever 'guessed at' before. So nice to get that buzz that I remember from my early days with a telescope. So, I was wondering just how many people have actually seen the Great Red Spot... I was using a 12" SW Flextube dob, with a 6mm eye
  10. Santa on a test flight Huhuh Aside from alien spacecraft and exploding meteors I might posit an unlikely but possible explanation. Could it be that you saw two shooting stars that just happened to appear in the same point in the sky... One going in one direction and then, just as that one burnt up as second along the exact same line of sight but travelling in different trajectory which, from your perspective, appeared to be at right angles. One hell of a coincidence but not beyond the bounds of posibility
  11. Hey Jas Yep, that's a nice job. Bit more professional than mine
  12. Hi John That is my understanding too. I suspect that drawing the air down the tube would have some effect but not so much as with the baffle. If I get chance tonight I will try and take a vid of an out of focus star. It's amazing to see the difference in thermal currents with the fan switched off and on. Without the fan you can see 'worms' squirming across the image... switch the fan on and the worms disappear to be replaced by diffraction rings. Still depends on seeing conditions but certainly an improvement. BH
  13. Good point Dave Yes, it has a marked effect on dew, namely you don't get any! I use a homemade shroud but even so I normally get problems with the secondary fogging up. However, now I can leave the scope out for hours and so long as the fan is running the mirrors stay clear. It also seems to be extremely effective at cooling. Normally takes at least an hour to cool but I checked after half an hour last night and the image was pretty clear. Just in time to spot Europa beginning its transit of Jupiter. (see my other post in the lounge) Wouldn't have been able to see this before I started using
  14. Hey James That was my original thought but I wanted something that I could slip on and off so as not to interfere with collimation. Don't know if you have similar troubles with your 10" dob... BH
  15. Hi all Just wanted to share my experience with a mod that has improved the view through my 12" SW dob. I've had the scope for 3 years and have always been disappointed with the views of planets and I was never able to see difraction rings on a star test due to 'poor seeing'. However, having become convinced that no one is that unlucky I began to explore other possible causes and soon learned about the Thermal Boundary Layer. This is a layer of warm air that sits above the surface of the primary mirror. Big mirrors struggle to reach thermal equalibrium so the TBL is nearly always in evidence. O
