  1. All the filters have now been SOLD Xagyl 5 position filter wheel and adapters still for sale. Open to a reasonable offer as I no longer use it. Francis
  2. Try fitting the guidescope forward and underneath the OTA. That's how I got over balancing my 6 inch RC
  3. Correct @Adam J. It takes 5x 1¼" mounted filters Francis
  4. Sales pending on the 1¼" LRGB set + 1¼" H-Alpha filter Sales also pending on the 2" H-Alpha and OIII filters. Thanks both.
  5. Lucky B, if only my neighbour was so thoughtful. Lots of hints dropped...
  6. Thanks, re photos and yes I retired from professional photography about 10 years ago...
  7. Grand worth the wait (knocks the spots off mine)
  8. Filter wheel added. I've checked it to make sure it still functions properly. Checked via 3 and 5 metre USB 2.0 cables with SGPro. Note slight discolouration to the anodising of one face where it was left on the scope in the sun. Happy to haggle on price if bought with the LRGB filters PM please don't just reply to this thread.
  9. Having switched to OSC I'm selling my 1¼" and 2" Baader CCD imaging filters and an IDAS NB-1 Nebula Booster filter 2". All purchased from FLO. Prices include UK Mainland postage. The Baader 1¼" LRGB filters I want to keep as a set. £150 SOLD The Baader 1¼" H-Alpha can be sold separately or with the LRGB filters £65 SOLD The Baader 2" H-Alpha and OII filters can be sold together or separately NOW SOLD H-Alpha £140 NOW SOLD - POSTED Baader OIII £95 NOW SOLD - POSTED Together £225 NOW SOLD The IDAS NB-1, £120 NOW SOLD - POSTED PM me with any questions
  10. From memory (I've now sold my SA) the USB socket is for firmware upgrades not a guiding interface. The SA I think has an ST 4 socket which connects to the guide camera to provide single axis guiding. I don't remember ever connecting my SA to a PC/laptop in use. See link below for PHD The only other external connection is a direct link to a DSLR camera via a jack socket... Link to my ST4 guide tests:
  11. Hi @AstroM1 Apologies for the late reply. If your imaging with the D5100 then to get clean stars right across the frame you will need a field flattener (I use the adjustable version and set as the manual (11.4mm) on it's engraved scale.) I have not cleaned the lens but I do use a dew heater strap so no moisture builds up on the front element. When not in use I keep the cap on to minimise dust spiders etc... I do keep the focuser rack clean with an old tooth brush to stop a build up of dirt/dust etc and a little furniture wax on the rack to reduce friction. Plus a damp cloth occassion
  12. Managed to get a few subs (7) on the Cone nebula area last night as a further test on my IDAS NBZ NB filter and OSC camera (ASi533 Pro cooled). Images processed in PI.
  13. Great image. I have one basic with RC collimation: Leave one adjuster locked and do all the remaining adjustments with the other two - that way you keep mirror spacing reasonably constant as small changes in separtion of the optics makes a big difference in the final focal length and the position of back focal plane.
  14. Are the filters the same optical diameter or are your older OIII & SII filters in heavier mounts? Some older filter mounts/holders have a smaller internal diameter than newer filter mounts - that may cause vignetting at the corners. Just a thought
  15. I wish my first lunar images were that good - especially the eyepiece projected shots
  16. Thanks ALL. Why the question? Well I've just spent money (too much of!) on an IDAS MBZ nebular filter for OSC cameras. I already had an IDAS NB-1 filter but I wanted to do a comparison between the two. This is the first stage of the comparison as these images were captured through an Altair Wave Series 115 APO Triplet @ f7 with a Planostar x1 flattener, via the above filters to an ASi533 OSC camera cooled to -12°C gain to 100. Capture via SG Pro, PHD 2 with multi star guiding, Processing in PI duplicating each process stage. Image A is via the NBZ filter, image B is via the NB-1
  17. Like some comments please. These images labled A & B were taken on consecutive nights (moon details on images) at the same times each night. Processing has been as identical as I can in PI (each process on one image copied to the other) then the pair put together in PS and a neutral background added. Optics, camera and exposure details identical for each. Preferances please...
  18. More details to follow... Basically: Altair 115 EDT APO with x1 planostar FF, ASi 533 cooled to -12°C and an IDAS NB-1 filter. 12x 300s subs for each image. Processed in PI.
