  1. Pm sent in case anything left
  2. thanks for the advice, I am using an OAG, the prism is parallel to the short edge of the sensor, but well out of the light path (but could be reflecting off the base of the prism holder, so it would be off to the left of this image. I will try taking this out of the imaging train to see how that changes things. Could it be something on the edge of the secondary perhaps?
  3. Yes it was definitely useful as a little project, essentially I ended up with a mono cam with 70-80fps with RAW output for about £5. The de-bayering process wasn't perfect so the outer edge of the images had to be cropped a little but it worked. I have very recently upgraded to an Atik GP however which offers a greater bit depth and far more sensitivity so the modded PS3 doesn't see any light anymore
  4. I have just finished installing a new Moonlite CR2 on my 190MN, after some collimation issues I finally got it all squared up and everything looked great, the Airy disk was reasonable (there is a strange blemish that i can't explain at the top), the corners were in focus and no oblong stars which is a huge improvement over the stock focusser. However when I came to image some brighter stars i noticed a strange diffraction spike style effect on the brighter stars in only the bottom part of my images. see below with a 400% crop of one of them. Any thoughts on what causes this?
  5. Got a response from FLO, looks like the Moonlite order has landed so hopefully get it next week sometime
  6. I queried it with Flo but last response was 20th March, I don’t want to pester (emailed them twice this week, no response), not sure what the delay is tbh as it’s now 8 weeks even if it arrived today .
  7. Anyone else waiting on Moonlite products, I ordered a CR2 on the 10th Feb through FLO but still not arrived. Seems a long time Keith
  8. That's a lovely shot, nice round stars and the star colours are visible without being over saturated, also captured plenty of fainter stars too in the background.
  9. Damp and moulds a real pain and sneaks up on your kit. I keep my 190MN and EQ6 out in a roll off shed, the roof is sound and internally its dry but essentially well ventilated due to the gap in the base for the pier and the whole thing being raised off the ground on castors. So far the scope has faired very well, except for the odd spider that likes to get inside the "sealed" tube and make lots of fine webs. The main issue I encountered was on the EQ6 mount, the counterweights have signs of rust and every screw/bolt has suffered with rust, also all the connections show sign of rust. I have now
  10. Hi Shibby, I have a MN190 and that exact OAG you linked to from FLO. I use mine with a Brightstar manual 4x2" filter wheel, Atik 383L+ and a QHY5L-II guide cam, I still have about 5-7mm spare back focus with this setup with the stock single speed Crayford (its an old mn190). Works a charm, however I do get a bit of sag with the stock focuser due to weight which causes focus shift across the image and not so perfect Flat correction,so im upgrading to a moonlite CR2. With this OAG you do need to make sure everything is nice and tight otherwise things will have too much play under load. HTH
  11. Left the scope running over night on his one when we had that cold snap, managed 42x10min luminance subs, added to some old 2x2 binned RGB data. This is a crop of the centre of the image to show off the galaxy detail a bit better. Pleased with this, although I might try a re-process when I’m not so tired. Atik 383L+ mono, 190MN, LRGB Baader filters thanks for looking.
  12. I still think the PS3 Eye cam has potential, you can get RAW data from it and so get superior detail than the regular RGB bayer interpolated data, also you can get about 70-80fps iirc, I'm planning on using the one I de-bayered (see link below for thread on the method I used), for Lunar again soon as I get chance. If I had the time I could improve the capture software a bit but barely have time to do the imaging as it is :O. One thing I haven't tried it on is planetary which is more challenging. Can pick them up for £5 or so on ebay.
  13. Afternoon All, After what seems like too long I have finally managed to do a bit more serious Astro imaging and revisit the forum (been over 2 years IIRC), as it turns out having two children under 5 and UK skies is not a good mix for a hobby in astronomy, especially if you value sleep. Anyhow in those 2 years of downtime have taken the time to tear down the EQ6, overhaul the bearings, take out some backlash, re-grease with lithium grease, flush out the cobwebs from the roll off shed, clean out the MN190 (also infested with spiders worryingly), retake darks and bias files and
  14. my word that is good, absolutely nailed it well worth the exposure time (shakes fist at UK cloud cover)
