  1. Okay so it looks like I need a focul reducer of around 0.5. What does the seeing part mean? Is that for sky conditions? I am near a town centre bortle 6.
  2. Hi, I have been thinking of moving on from taking snaps with my smartphone. I am not rushing into a purchase. I know next to nothing about imaging but from the bits of advice I have tried to piece together it seems it would be easiest to start with a colour camera? I would like as easy to use as possible for a beginner. My scope is a 12” F5.3 dob. 1600mm focul length. I know it’s not ideal for imaging but I just would like to improve on my smartphone images of planets and some of the brighter DSO’s such as Orions Nebula. Looking at the prices as well it seems to be between the ASI 120MC-S, 224MC, 290MC, 178MC or the 385MC. What is the difference between them? I have had a look at the field of view images but I’m struggling to tell the difference. It seems I would need a Barlow as well. The cameras I mentioned are all here https://www.firstlightoptics.com/zwo-summer-sale.html let me know if there are any essential accessories too please. Any advice would be greatly appreciated, Thanks.
  3. Interesting. You may get an email from me before this offer ends.
  4. Wow. Looks like I picked a good one for my "finder piece" which is the ES 82 degree's 30mm. It's clearly more than just that.
  5. Stu, I know I’ve already replied to this but I can’t work out how you knew my name was Mike? I need to change my username I didn’t realise how annoying my abbreviation would be. Prefer to be addressed as Mike!
  6. When do you use the 14mm Delos over the 13mm Ethos?
  7. I’ve learned a bit there about the focul positions thank you. I heard about the field curvature on the larger XW’s too. I’ve done a lot of searching and reading back some great old discussions on here.
  8. What Delos do you have? I don’t plan on buying more Pentax. Not that I’ve got a problem with them but if I feel I wanted to try get a sharper view then I would be tempted to try Delos next just to see, first in some of the sizes I don’t have at the moment. It seems a coin toss or slight personal preference between XW’s and Delos under 14mm.
  9. Yes I got my Cheshire now and haven’t thought about collimation since because it’s been cloudy. I’ve deleted fancy collimation stuff from my wish list and went back to sorting my eyepieces and filters. I’m alright for filters for now too so getting there.
  10. Yes I use my Myriads most. I can’t see a downside to them over my 5mm Pentax XW apart from comfort but I don’t have the most trained eye yet. I see no colour problems. Contrast seems spot on. I ordered a 7mm Pentax to fill a gap with my longer focul length scope but if I fill any more gaps I think it will be Delos. Hopefully I stop getting tempted but feel good for narrowing this down now. Going to a darker sky site with my brother when he is over for a couple of weeks in August so can’t wait. Will just try get that 13mm APM Lunt before then.
  11. I’ve decided to go for the APM Lunt XWA 13mm for now as I want a wide field. This would complete my eyepiece collection for now until I add some Delos in the long term. I can’t see a problem with my Myriads visually apart from the eye relief and awkward eyecup not being great but it’s okay, optically they seem spot on. Considered an ES 100 degrees 14mm but the weight put me off as it would need more balancing I think. Not worth it for one eyepiece. I think I’m parting with the idea of any Naglers too as I would end up with too many eyepieces that would be wasteful.

    APM Lunt XWA 13mm

    I know there probably isn’t many around but if anybody has one they would part with then let me know please
  13. Sorry guys meant to post this in the “getting started with observing” section. Although perhaps not so much a “getting started question”. I mentioned Naglers because they have a very broad range and field of view at the moment is important to me as I’m learning my way around the sky star hopping. Although I’m thinking of getting the next I see some up second hand between APM Lunt 13mm, ES 100 degrees 14mm and Nagler 13mm. Sorry for all the posts just thinking too much.
  14. Just DSO’s in general, I’m still getting the hang of all this. The easiest ones for now! I also have a 30mm eyepiece that gives me 5.66mm. Just trying to plan my set which is quite difficult. I’m sorted with planetary with Pentax XW and possibly Delos. Also have a 3.5 and 5mm XWA. The 5 could be used for cores as you say as that’s around 1mm. Thought I would experiment with exit pupil to get the brightness right and filters too. I think I’ll get a 13 or or 14mm 82-100 degree next as that seems to be what i’m missing most. it’s a real mix and match. Drives you mad. I’m going to end up with a full set of Naglers on top before I decide what to keep it’s all fun anyway.
  15. I hear a lot of around 2mm being ideal. Which in my scope would be an 11mm eyepiece. I currently have 9 and 20mm eyepieces that give 1.7mm and 3.78mm. Will probably get a 13 or 14mm next which would be exit pupil of 2.45mm or 2.64mm a 16mm eyepiece would give me 3.02mm. 17mm would give me 3.21mm. What do you use? Answers in exit pupil please for now.
