  1. Correct - LR does not support bmp files - you'll need to convert them
  2. Following the recent deforking of my Celestron C11 Nexstar GPS, the original fork mount/base, tripod and the Milburn wedge are now for sale Items are i) Milburn Deluxe wedge with keypad holder - 1" aluminium, powder coated black - built like a tank, - currently drilled to accept A Celestron C11 Nexstar GPS C11, but could be drilled for other SCT bases - see http://www.milburnwedge.com/. Its circa 2007 vintage and originally cost ~£500. Weighs ~ 50lbs ii) Celestron Field Tripod as supplied with the Nexstar 11 - 2003 vintage so showing some wear & tear - weighs ~20lb. I'll throw in a set of vibration suppression pads with this iii) Celestron Nexstar 11 Forks & base (no OTA - that's now on my EQ8) - 2003 vintage. it's showing its age - paint is flaking off the metal parts of the forks - complete with hand controller, RS232 programming cable and RS232 PC Control cable. The hand controller & motor controller firmware cannot be upgraded any further - versions are - Hand controller v2.2, motor controller v4.6. I only ever did planetary/lunar and video based DSO imaging - it was capable of ~10 second unguided exposures @f/5 for DSOs. Weighs ~35lbs Please see pics for detailed condition . Happy to provide further details if required All items were housed either in my home built observatory (2003 - 2007) or the replacement Pulsar dome - 2007 - present Prices:- Milburn Wedge - £150 Tripod - £50 Forks & Base - £75 or sensible offers. Payment - cash or paypal. Given the size and weight of these things - prefer 'collection only' or a '1/2 way meet with 100 miles' from the New Forest - as shipping would be extortionate but could be negotiated.
  3. thanks everyone - L subs it will be. And of course, if i do the L first at least I'll have something to build a monochrome image with. Neil
  4. Am I being a bit dim here, but if I'm taking my R, G, B subs all at full resolution of the camera - no binning - (cam is an ASI 1600MM-Cool), then I'm assuming that I don't need any L subs? My understanding is that I only need L sub if I'm binning the RGB to enhance the detail. Thanks in advance Neil
  5. I also think that there is a new astro society on Tenerife, so might be worth contacting them -
  6. Ditto - probably aimed at the US market ready for their eclipse later this year
  7. This was my life-saver:- - somewhere around 3rd or 4th post are pics and instructions
  8. With Sharpcap:- i) set the exposure required in the exposure window on right hand side, ii)then Select 'start capture' from menu, iii) then check 'single frame' button and check the 'capture a sequence' checkbox iv) set 'sequence length' =the number of frames you want to capture and 'interval between captures' = the delay between them v) press the 'start' button. hope this helps Neil
  9. SCTs benefit greatly from a dew shield (make out of a camping mat) and dew heater
  10. Thanks for the tips.
  11. A few 'firsts' for me here:- First ever RGB image First ever image processed in Pixinsight - all thanks to HarrysAstroShed tutorials First 'proper' use of ASI 1600MM-C with Mini EFW First image through the OpticStar 127mm Apo R,G and B - 30 subs each @8 seconds with ASI1600MM-C set to unit gain, offset 21 and @-20C I have a lot to learn (many more tutorials on Harry's site, the LightVortex site and also Warren Keller's book) - but its a start. Now - How do I get my luminance image (60 subs - other settings as above) incorporated Next time I'll get the framing correct to get the Horsehead too Neil
  12. good point - I attach my camera (not a dslr) directly from the reducer (I've got the f3.3 version - can't use for visual) with another type of adapter (T2 to c mount) - so I don't need the second click lock. - don't do visual that much and wouldn't attempt it with the reducer in place. (I've got a 127mm APO for visual use )
  13. Yep, my first time up Teide I thought it was cloudy - until I realized it was the Milky Way!
  14. It was bound to be clear down here - I'm recovering from a knee op and so can't get in my dome for a few more days. I forecast clouds in the south from about next Tuesday
