I managed a couple of hours on M45 the other night while very clear. Took the opportunity to do some visual with my 200p dob. Luckily the below freezing temperature inhibited dewing on the 130's secondary.

Does anyone store their 130PDS in a padded bag? If so what do you use? I've got a geoptik one for my 200PDS, need something similar but a bit cheaper! :) Cheers.

I hang mine off a hook on the roof of my workshop.

My scope finally arrived. But there is something strange- a piece of cork washer under the mirror. Is that normal? I send back scope to the seller...

cork is commonly used as a cushion for the mirror. if you look carefully there will be at least 3 cork pads. The one you can see might be a little out of position but the gap between the mirror bottom and the white aluminium cell should be even all round if they are in place.

search "cork in mirror cell" if you need more reassurance

If you want to see what a mirror cell looks like when the mirror is removed there is a 8 inch cell for sale on Ebay with pictures showing the three cork pads next to the collimation screws. Ebay number

Hi

Does the black shower cap work OK then ? Could be just what I am looking for !

Thanks.

Hi. yes. Note, there's an elastic band to hold it in place.

These design types seem to have made the diameter of the cap stretch to the size of an average human head, with little regard for preventing light entering the mirror cell of a 130pds. Ridiculous.

A dreamy rosette, but unfortunately running out of frame. The nebula extends further than suggested by kstars. Or -far more likely- I entered the focal length incorrectly in the first place. Maybe a two frame mosaic?

Comments for improvement always appreciated.

Thanks for looking.

It's a wonderful render of the rosette and the star colour is good.

I'll reluctantly give you the bin bag. However your elastic band  looks positively professional. 

Call it quits?

Just the standard one that came with the scope.

At a guess, and after carefully studying the photo for several seconds, I'd guess it's the same length as the standard one that came with the scope 🙂

What guide scope will be better- 50/190 or 60/240? My camera is asi120mm mini (3.75 pixel size).

The smaller one will be fine, I use a 50/183 with a 120MC and guide to ~0.6" when the sky is nice and clear.

Last question- can i put this tube to celestron avx? Will handle it for ap well?

Yes, it's possible.

With careful balance, I've done 600s guided subs with that combination and a MILC/DSLR.

YMMV

Posted this elsewhere, but after some serious rework I'm happy to add this to the thread, despite a few disasters on data collection. Binned 50%, Ha Sii Oiii, ASI1600 mono.

I can't believe that this thread is still going strong after 111 pages of discussion and pictures.

Looking to get back into the astrophotography, anybody got any tips for keeping bright stars from blowing out? Especially in areas such as the Horse Head Nebula.

Welcome home Galen!

I've found that 99% of the time its really a case of being careful with stretches. Use curves not gamma and keep the upper part of the curve from levelling off.

That way I've always managed to keep Alnitak separate from its companion, even with 5 minute exposures.

Of course it's easy with a Ha filter...

      I'm tempted to go down the route of getting myself a brand new reflector...  My friend's old Meade 114/900 is a good telescope, but I want something of my own and with a bit more light gathering power.  To this end, I've been looking at a couple of different models and manufactures.

      I must admit, the Skywatcher Explorer 130M floats my boat, as it's motorised with a speed controller.
      Any thoughts or observations?🤔

      Celestron C8 XLT + extras and SkyWatcher Star Travel 80 (ST80)
      I have a Celestron C8 with XLT Starbrite coatings. Will include the full length base plate, both visual and imaging backs, scope rings, front 8" end cap and the finder scope with it. No box I'm afraid. Optics are good and clean, focal length is huge - 2300mm from memory. This lot would cost close to £1300 new and one with less spec went for £750 on fleabay recently. Might be interested in a part exchange or will let it go for £450 collection only.
      Also, I have a SkyWatcher Star Traveler 80 - good optics, used as a guide scope - just the scope itself (does not include the barlow in the photo) - now including dovetail bar and scope rings looking at around £50 for it.
      I have decided to save up for another refractor, WO, Equinox or even toward an Esprit. However, I would also consider p/ex for an Intel NUC and/or Pegasus Astro Pocket Powerbox.
      Please excuse some of the colours - I used my astro modded 6D which was in the observatory so the "nice" purple is actually black !!
      Both these are collection only.

      I am going to buy Skywatcher EQ5 Pro Go-To mount. But, unfortunately, I am low on budget.
      So, does someone know where can I buy the cheapest EQ5 pro mount?
      Yesterday there was a low price for it (350 €), but they changed it.
      Thank you for your time!

      I found this setup in internet and make me think, with AZEQ6 GT and 2 scopes, different weights and size, without counterweight in AZ mode! 
      - I can put a MAK100mm 3kg +- and a OO VX10l  12kg +- without counterweight?
       
      Does anyone have this setup mount and already used without counterweight with two telescopes of different weights? Is it really necessary to have a balance using in AZ mode?
      The problem to centralize the object with both scopes is true? With the SW AZEQ6 GT?
      Follow the images
      a TSA-120 with 6.5 kg i think and the other with 22kg i forgot the brand hehe you can help me?

      Selling a nice portable wide telescope with great glass and a great field of view
      I have two telescopes and I'm using the 80ED more currently and so this Telescope just isn't getting used anymore
      It has a longer dovetail (originally from the 80ED) so declination balance can be reached.
      Great performer for the price
      Collection only as P&P is like £40 (Northamptonshire - UK)
      Selling to fund a scope or mount upgrade.🤔
      Selling
