  1. A user on here looks to be selling one
  2. A show about the history of the telescope is on now and on +1 at 7 am for anyone that is interested.
  3. I have seen it on the tv a few times, it apparently sits behind clouds !
  4. Good idea and along the same thoughts as myself.
  5. I’m guessing the cladding helps as well. Thanks, I feel more confident going forward with blocks now.
  6. That’s reassuring Peter, are you U.K. based ?
  7. I guess the question is am I kidding myself that a block build wouldn’t cause me any issues as I’m even questioning myself !
  8. I posted a while ago about future plans for an observatory and recently this has become a green light viable project. I currently have an old pre fab 6m x 2.7m garage that was inherited when we bought the house. Being very old and now in desperate need of being replaced but as the title states I would like to build it with concrete blocks incorporating a 2.5m scope room.1.5m warm room and the other 2m for storage/workshop . My reasoning for blocks is longevity, less maintenance and the future ability to convert it back to a traditional garage if circumstances etc change. I have researched this and I’m aware of the thermal retention of the blocks but don’t see this as a big problem in the U.K. I could even clad the sides with shiplap to take and direct heat off the surface of the blocks during the day from the sun to aid them not warming up to much in the first place. there are a couple of well known users on here that have block/brick observatory's that reside in Spain who haven’t reported any issues. Your feedback being positive or negative is more than welcome. cheers, Dan.
  9. If you do split I would be interested in the o111 & s11 filters. Dan.
  10. New tripod and a crystal ball for predicting clear skies
  11. As the title really....I captured 4 hours a couple of weeks ago (bottle 6) 2 hours lum & about 40 minutes each RGB. I wasn’t expecting the dust to exactly leap out but maybe a little more than I got from my processed image. I have read that this target is probably better suited to being captured in darker skies. I realise the more data the better but I’m not sure to keep going with it over a few more nights or to turn my attention to a Galaxy. I didn’t save my processed image so can’t post but can share the stacked LRGB data. ASI183mm pro @ unity gain 120s subs for all. Dan.
  12. This data is from late last year and my original final image was not the best so I have eventually got round to re processing it. I'm still not 100% happy with it but much better than the original. Lum 44 x 120s Red 15 x 120s Green 15 x 120s Blue 14 x 120s
  13. I can’t comment on the ZWO filters but when I started with mono I couldn’t afford everything in one go so just bought my camera and a Baader Ha filter just to get me going. The camera (if ZWO)should come with an adapter to accept a single filter so not essential for an EFW straight away (for me anyway). One thing I will say as it was also mentioned to me was do you plan on going narrowband and broadband ? If so a 7/8 position wheel will be better from the off. I did go 5 position but got a used one for a £100 but will need a larger wheel in the near future. May be worth mentioning your choice of camera as slightly bigger filters work better with certain sensor sizes.....but someone with more knowledge than me will be able to advise better than me on this.
  14. I made the transition from a DSLR to mono last year and was initially apprehensive especially with what a lot say “I can’t be doing with all the faff” but does require an initial outlay of some more £££ It genuinely isn’t a faff and with your filters in an EFW this and your camera just connect to the scope and that’s the difference in setup. Image acquisition is just a case of setting a plan up in your software and away you go pretty much the same as an OSC. Processing is more in-depth but the way I see it is there are so many crappy nights that I can’t get out due to weather that there is plenty of time to learn new/practice processing skills. As @wimvb has said you can shoot all filters in one night so as a rough example LLLRGB and just repeat this over and over again ....no need to capture Lum one night Red another etc. Not the most technical post but these were some of my initial concerns before I made the decision to go mono and I’m more than happy with my choice.
