I've been imaging for a couple of years so have a great deal to learn. I have an Askar FMA180 scope and although I'm quite happy with the few images I've taken there is the problem of blue star bloat. I know that the Astronomik L3 filter will address this problem and I have bought one but I'd also like to capture the colours of emission nebulae. Is it feasible to use an EFW with the L3 filter and also my Optolong L-Enhance? I will be using my ASI533mc pro camera.

I am sure you noted we weren't talking EQ mode ?

I've apologized for the confusion already, is that ok?

As you can see when in alt az mode the levelling base is not visible so the mounts bubble must be used but when in eq mode the bases bubble is visible, sorry for the confusion.

Yes but as I asked does it easily attach to the gti mount / tripod if one decided to buy one and use it as you mention its better performance ? Can you attach a photo or two ?

Yes indeed you did. It does attach easily but you can't then have sight of the bubble on the levelling base as it's smaller than the mount so then have to rely on the mounts bubble. It's only when used when the mount is in eq mode that the based bubble is visible. I'll try and provide some photos later.

I've realised that I use it with the bubble on the mount as reference but it seems more accurate and much easier than levelling with the tripod legs, apologies🙄.

I found when I relied on the mount levelling bubble I had persistent errors so I used a levelling base that I already had from my landscape photography, that seemed to clear up the problems for me.

As has been said the Classified section here is the first choice but I have extensively used Facebook marketplace. There are 2 groups that are exclusively UK based and you can find them easily enough, both seem well moderated.

Of course if you don't/won't use Facebook which is perfectly understandable then the other options can be explored. eBay is a dogs dinner and IMHO best avoided.

The BBC weather app shows a completely clear night, no clouds at all, however the ClearOutside app shows heavy cloud cover.

Bit of a dilemma so what to do? Simples, I deleted ClearOutside and kept the BBC app so it's going to be clear. Just set up to do a whole nights astrophotography, what could go wrong?

I've wanted one of these for some time to avoid the snaking cables across the lawn when using my larger rig or the collection of power bricks when using my Az GTi when visiting family but I could never justify the expense to my Domestic Financial Supervisor. Of course I could easily justify it! Quite randomly I hit upon the Jackery website a couple of days ago while researching something else and was intrigued by the 40% Summer Sale price reduction. Because of the cut off date being the next day I hastily arranged a meeting with the DFS and received approval. The normal price is £260 and I got it for £158. It's the baby of their range but quite adequate for my needs.

Sad to see about the Narrowband channel presenter. He does a great show. I was thinking he looked a bit gaunt recently.

Wishing him all the best. He'll of a position to be in, with three kids at that age. 

It's awful news especially for such a young man with a young family but he has a wonderful attitude.

Well done Lee.

Really excellent image.

Cheers Fozzy. I think I'll just purchase the SVBony 80ED version at £45.99. As the guy said, it works perfectly well.

Where have you seen that one?

It will be my 50th birthday on Sunday so I couldn't resist purchasing another az gti along with a pillar for myself. Purely for use on my visual setup with my ST80 and SM90. Also to use on some planetary and lunar imaging, all in az mode. 

Just love this little mount so much.

I had two AzGti some time ago and used them in exactly the way you intend. I sold one thinking it was superfluous and have regretted it ever since.

PS you don't look 50, must be the air in Cornwall, happy birthday.

How did you fit the Skywatcher electric focuser? I had to buy a 3D printed kit for the focuser motor. I’ve since sold the telescope. It does make a considerable difference in focusing though.

I bought a 3d printed kit from a chap in Portugal, works very well and possibly the same as yours.

My upgrades for that kit:

Skywatcher electronic focuser, zoom eyepiece, in my case the Baader but cheaper ones will do the job. A dew shield, a Telrad with heater element and a Trifibre case, it weighs a ton but it holds everything. Last but not least is the battery pack/brick mentioned by @AstroNebulee, I use the smaller Talentcell from Amazon and it lasts for ages.

We're going to France next week in our motorhome for 4 weeks and I'm looking to travel to dark(ish) sites in the Western half of France ie to the west of the River Rhone. Be grateful for any recommendations.

@LaurenceT did you save any of the images you got?  I'd be interested to see what you are getting with your setup.

Haven't been able to do much recently but spent the last week struggling to get anything using my Startravel 102/ASI224mc combination with the Stellarmate. Can't seem to get any image but it works with Sharpcap. Anyway, last night reverted to the original Evoguide 50ED setup and got a simple screen grab of the Globular Cluster.

It seems that I've finally almost tamed the very unruly Stellarmate app. The first few times it was extremely slow to show the different targets available, so slow in fact that I'd thought it had frozen but it hadn't. Someone had suggested that I tried a USB SSD for the Stellarmate OS so I bought one but that was just as buggy. Reverting to the micro SD card as if by magic the bugginess had gone and it worked almost perfectly.

Last night I had about 45 minutes of clear skies and I was able to observe the Iris nebula, Bodes Galaxy, both very small and faint, but spent a long time looking at the Hercules Globular cluster. The Hercules seems to be the best target from my garden at the moment and it's beautiful. At the moment I'm not taking images for processing, the observing is satisfying enough but I will perhaps try and get a screen grab on my Ipad.

I think he is talking about the filter thickness changing the back focus slightly. At least that’s what I read into it.

Yep, that's it.

I'll have a look later.

I'm not sure what you mean by using spacers with filters. I don't use spacers with my filter wheel. The only time I use spacers is to set the correct back focus when using a x0.6 reducer.

Could you explain what you do with filters and spacers for AP?

 

 

The question came up when I was having some problems with my Askar FM180 and spacers were discussed, I don't use a filter wheel. I then did some research and saw this YT video which explained things more clearly for me.

One thing that simply didn't occur to me when I recently started astrophotography was the use of spacers when including filters in the optical train. Would the use of such a spacer improve the visual quality of EEA observation or is this not so critical?

One of the advantages of EAA is that you can still observe with light pollution, and when the Moon is bright. Observing close to the Moon isn't great (bright patches around the edges of the image) but since you don't need to be dark adapted you can still observe objects further away from the Moon.

All of your scopes, except the Dob and perhaps the Mak, would be good for EAA.

 

Being an absolute novice at astronomy and an elderly one at that I think that this will revolutionise my observing and learning where stuff is in the sky. I'll now be able to observe distant objects that normally could only be viewed with large, heavy and in some cases very expensive telescopes and eyepieces.

I was struck how easy it was last night to get going, levelling the mount and scope and pointing north took a couple of minutes and the Stellarmate app was taking me to targets within another couple of minutes. The app can be a bit flaky and getting the app to control the mount by WiFi was an exercise in futility.

I've got no plans to use EEVA as a crossover to astrophotography, I already have gear for that but it's interesting to see how controversial that can be.

I decided to follow the YT video on a simple home made so-called "smart telescope" by Cuiv and after faffing about for a few days with wifi I abandoned that and last night finally got to test the rig using stacking in Stellarmate. I already had most of the gear, all I needed was a Raspberry Pi and some cables. The setup consisted of an Evoguide 50ED, a ZWO ASI224mc camera mounted on an Az GTi controlled by the Pi.

Although the moon was already washing out my light polluted skies I saw the Whale galaxy, Bodes galaxy and the Beehive cluster. I also saw various globular clusters. I'm pleased with this so far and I will use some different scopes and a different camera soon.
