  1. Great image Adam, I like my 800E too. Just a shame it's so heavy!
  2. If you go west of Wolverhampton - eg: past Shipley, there are a number of villages most will have recreation grounds which can give good horizons...

    Francis-Astro images

    Images taken using a mix of mono DSLR, OSC DSLR, Cooled OSC cameras on observatory mounted telescopes
  4. Skies cleared for a short while early evening. Just got 3x 5min abd 3x 3min subs using an IDAS NB-1 2 inch filter with the ASi 533 MC Pro. Image uncropped, processed in PI only. Overal image scale reduced for uploading.
  5. With the weather lately I did a daylight collimation on the RC6 using a peep sight (sight cap) and earlier tonight spent 20 mins fine tuning the collimation using Alpheratz as the target and x200 screen mag. I've fitted a set of homemade collimation knobs to the secondary housing which proved a bonus. Just managed a few subs on NGC281 using the Nikon D5100, guided with a TS 60mm guide scope fitted with an ASi120mm. Captured via SGP, processing PI, guided PHD2 and plate solved with SATAP - first time using this for plate solving, not sure I'll go back to Plate Solve 2 now. ASTAP is so fast.
  6. Have you tried enlarging/reducing the images to the same diameter as contrast in the systems seems to be a factor too.
  7. I've been using Plate Solve II in SG Pro for quite a while and found recently I've been getting a lot of failed solves. There are other options in SG Pro like ASTAP which has some more encouraging reviews lately. Anyone using ASTAP in SG Pro? any pitfalls to look out for? I've downloaded ASTAP and it's G17 catalogue. Thanks
  8. There should be 230mm from the back of the OTA to the sensor
  9. Thanks John, Yes I went with the SS V2 - ordered yesterday after watching loads of videos (the Italian demonstrator's a bit OTT for me!). I liked the idea of no 'L' bracket and the attachment is certainly solid. It arrived this morning (thanks FLO) and it's now fitted and calibrated. I found the travel motion reversed OUT being IN etc... And I didn't read the instructions either. Need some clear skies to try it out now.
  10. Now I've had an initial play with the scope I'm looking to accessorise and the first thing will be to motorise the focuser. I've been reading specs on the Pegaus Focus Cube v2 and the Primaluce Lab Sesto Senso V2 both offer multiple adapter couplings to fit different focuser units, the Pegasus offers a 6Kg load lift and the Sesto Senso ?Kg (not shown). The Pegasus also comes with a temp sensor and all the hardware to fit to my focuser (via an L bracket). The Sesto Senso doesn't appear to need a bracket for mounting and photos I've seen of the unit don't really show how it fits very well?. Sesto Senso has wifi so I could use via an iPad... Anyone use these units (not necessarilly on an RC) how do you find them and their related software etc. I'd be using via SG Pro mainly.
  11. From the kitchen window this morning.... Nikon 800E with 200mm at f3.5 1/60s hand held
  12. Continued playing last night with the new StellaLyra RC6 OTA in combination with my CEM25P. I've kept all the subs to 60s @ 800 iso using the monochrome modified Nikon D5100. No filters, no guiding and no cooling. The Helix nebula (NGC7293) was first as it had pretty well crossed my south fov before I'd realised, this is just 5x 60s subs processed in PI with darks, no flats or bias frames. IC1805 (part of), few more subs on this: 15x 60s, processed in PI with darks, no flats or bias frames. M76, I captured 10 subs on this and was able to use them all, again: processed in PI with darks, no flats or bias frames. Finally M74. Twelve subs on this. I shot 16 but suffered some trailing and a satellite so just ditched those, all processed in PI with darks, no flats or bias frames. Next will be sorting out some guiding and pay more attention to focus. I made the mistake of not checking focus after the initial start up. Thanks for looking
  13. For once I actually like SHO - Great imaging
  14. Thanks Mark - As to visual I'm not sure. I'm not a visual kind of guy but I did take a quick look at Jupiter and Saturn last night. There was quite a bit of variable cloud but to me the view was worth it. Mars was still behind trees for me when I packed away. I've found the intervalometer so I can get some longer subs and hopefully more of them. Always liked 891 since imaging it with a friend many years ago and watching the prints develop in a darkroom...
