It'd be more secure to pack the OTA OD rather than the rings ID, you've got more surface area to play with.

Your right...never actually thought of that.

What size do you actually need and how much gap needs to be taken up if you use the 10" rings?

30mm...so something like 15mm of a gap all round.

Hello all I have an ota that is really difficult to find tube rings that fit,for example SW rings to fit an 8" ota are you small...rings to fit a10" ota are you big.

I thought I would buy the 10" rings and someway try and pack the inside with something to make them fit,maybe 15mm hard rubber strip...any ideas what could work.

Thanks Paul.

When the bright star is centered there is no spike and when off centre the spike is there...what do you think,loose filter.

Bit of thin cloud in first image.

Hello all,any ideas what is causing the spikes on Alnitak,using a frac with l-enhance, efw and reducer/flattener.

Few images over the year with what rare clear skies we had.

Raw 120 sec pic with a Gail blowing.

Could be a nice comet.

Yea,was curious how you got back focus.

My granda told me about it..🤥🤥

"We choose to process......not because it is easy...we choose to process because it is hard".

Swear I heard something along those lines said before.🤔🤔😁.

Panic over. I had a friend who helped me carry the boxes off the pallet and into the house. He also cut the straps and opened the boxes for me while I was in the toilet. He said that he only threw a piece of packing in the bin outside. When he told me that on the phone I immediately went to the bin and retrieved it. Lo and behold nestled inside what indeed does look like packing were the missing parts. I asked him “ didn’t the suspected packing seem heavy to you?”. He simply shrugged his shoulders. Now to assembly. Thanks.

With friends like that..who needs enemies...😁😁

Around 100x30 sec subs, uv-ir filter, 102ed 533mc pro.

If you want to locate the comet visually now's the chance, right beside Vega.

Hello all, thinking about maybe buying the essential version of this scope.

I currently own a 102ed doublet  with 3" focuser, which I have been and still am very pleased with, would it be a good idea to change to the ES triplet...any advice greatly appreciated.

Quick 180 sec raw shot of the comet,actually looks like it could be good...not the pic,the comet.

Do your 8 second subs give you a non-blown out core and separation of Trapezium stars when un-stretched? If so, maybe HDR compression would still work. Not sure what post-processing tools you use and whether this is an option?

Yes a bit blown out,I use APP...actually just came across 2,4,6,8 and 10 sec subs I must have done earlier in the month and the 2 sec clearly shows the Trapezium so will give it one last try with shorter subs.

Can never get this right,always burning out the core so I tried 8 sec subs around 450 of them still the same....🥴 Any way probably won't give it another go.

Hope there is a nice ZWO related prize.....😁

Thanks Paul I used 120s from a bortle 4/5 site. Do you reckon still 135gain is to high?

Sorry mate,just re read your post..for some reason only known to my brain...I thought you used a 533 mc...🥴,still a great image...I'll get my coat.

Thanks Paul Will try lower gain next time, What exposure did you use for your subs?

I did a redo Hope this looks better?

 

That's much better...I used 180 sec subs from bortel 8.

MiYou should keep your gain to 100 or 101, you should have a lot more detail with the time spent on this object.  This was under 7 hours using same equipment 

Bit of Planetary.......

Not ideal conditions with storm Debi just passed, but ok.
