  1. Not taken a Sun pic for three months!! However all is not lost as I have only missed a dozen tiny spots as we are passing through solar minimum. Usual rig of 120mm APO refractor, Baader Solar film ND 5.0, Canon 1100D, ISO 100, 1/3200 sec exposure. 120 still frames taken. Trimmed in Pipp and then stacked in Registax 5. Photoshop to finish and add false colour.
  2. I would suggest drilling for the nails- maybe drill 3mm for the 3.5mm size. The nails will still grip but you won't split the timber and it won't split later either. Those SS annular ring nails are real devils to remove!! By the way drilling also helps keep the nails going in straight and you get far fewer "bendy" ones. You can pre-drill quite a few planks at one go then spend a happy ten minutes annoying the neighbours whilst you bash 'em in with an 'ammer??? (Nails that is not neighbours!!).
  3. That is very good indeed! You have captured the surface granulation and faculae (the bright streaks) around the Sunspots. The orientation looks pretty good as well.
  4. I used "shed" grade EDPM and it did the job well. It is now four winters old and is 100% waterproof. It is heavy, so really a two person install is easier - especially lifting it onto the roof. The glue I used resembled thick treacle but worked well - I think it was water based as it had no discernible odour. Mine was bonded directly onto plywood. The only issue was a black mold of some sort on the underside of the ply after the first winter. A liberal coating of anti-fungal paint has stopped that in its tracks.
  5. Please read the instructions in the first post of this thread and put each of your entries in a new topic. Pictures posted in this thread will not be judged.
  6. Spotless - even so, good images in both lights.
  7. You may find one on a site like Astrobuysell or try our very own Wanted section.
  8. It appears you intend to bolt the wheels in place - this will allow you to align things before tightening as you suggest. I would also recommend using either a drilled plate or very large washer(s) on top of your timbers so that tightening the bolts does not simply crush the timber rails. I wouldn't leave things loose as any slop will just encourage wear in the timber and could lead to embarassment in the future!
  9. I would also suggest the six wheel layout. That said, whether using four or six, if the structure is rigid only three of them will ever be taking the load!
  10. I assume you mean the exposed wooden rails that the roof will roll onto? Mine are simply painted with shed paint which has lasted well so far - about 3-4 coats as I recall.
  11. AR 2708 is still eeking out an existence today:
  12. That's good - exposure and focus both pretty much spot on.
  13. Nice ones! CaK seems to be showing 2 AR's but white light only the one.
  14. If you convert your image to JPEg it will show on the forum (or PNG). At the moment we cannot see it.
  15. If you dismantle an old (or cheap/damaged) pair of binoculars (10x50 or 10x60 or similar) you can make two small refractors of the "cardboard tube" variety. Done well you will have quite a decent little pair of scopes. Discard the prisms and use the Object lenses and eyepieces to get a simple "straight through" optical path. A plywood altazimuth mount and timber tripod should make a stable mount for them. I just had a look at "for spares or repair" on a well known auction site and a very few pounds will get you a pair of well used and grubby bins that would do the job.
  16. AR 2708 is just about hanging in there!
  17. Todays Sun with a tiny new AR to see:
  18. Very nice and excellent close ups of trhe new group.
  19. I believe EQMOD/ASCOM works withthe EQ3 mount. Its freeware which is always helpful! http://eq-mod.sourceforge.net/ is a good place to start - also Chris Shillito's Youtube channel: Chris Shillito will explain things.
  20. Those are excellent first Solar Images! Welcome to the light side!! To help: Get the ISO as low as you can and try a shutter speed of 1/2000 sec (or nearest - if in doubt shorter - the Sun is very bright even through a Baader film!). Then try taking a few dozen pictures and stacking them - you will be surprised at the result you will get. Have a look here to help you get started: Solar imaging tutorial and keep up the good work!
  21. This is a 2 pane mosaic of the Lunar "X" taken on 22 April 2018. ED120APO and ASI120mm mono camera. Each pane taken using a 2.5x Powermate giving an effective focal length of 2250mm. Processed in PIPP, Autostakkert!3, Astra Image and Photoshop. 200/2000 frames stacked for each pane.
  22. A bit slow processing these but finally done - The Moon with the "X" and "V" on display from last night. ED120APO, ASI120mm mono camera, 2.5x Powermate for the close-ups. Processed in PIPP, Autostakkert!3, Astra Image and Photoshop for a final tweak! The main image is a five pane mosaic - each pane 200/2000 frames taken (one was a pig where the scope/ camera or something moved and I had to crop about 50 frames from the end of the AVI - I think i may have walked past the scope and I must have nudged it! Close-ups as above ie 200/2000 frames each pane - one a single and one a two pane mosaic. Please click to get the full sized image:
